SJ300 Inverter 1–13 The Purpose of Motor Speed Control for Industry Hitachi inverters provide accurate speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor.
Geting Started 1–14 Introduction to Variable-Frequency Drives vector is related to motor flux current, and the other to motor torque current. The ability to separately control these two vectors is what allows the SJ300 to deliver extraordinary lowspeed performance and speed control accuracy. Inverter Input and The Hitachi SJ300 Series of inverters includes two sub-groups: the 200V class and the 400V class inverters.
1–15 SJ300 Inverter Much of this manual is devoted to describing how to use inverter functions and how to configure inverter parameters. The inverter is microprocessor-controlled, and has many independent functions. The microprocessor has an on-board EEPROM for parameter storage. The inverter’s front panel keypad provides access to all functions and parameters, which you can access through other devices as well. The general name for all these devices is the digital operator, or digital operator panel.
Geting Started 1–16 Introduction to Variable-Frequency Drives Acceleration and deceleration settings specify the time required to go from a stop to maximum frequency (or visa versa). The Speed resulting slope (speed change divided by time) is the acceleration or deceleration. An increase in output frequency uses the acceleration slope, while a decrease uses the deceleration slope. The accel or decel time a particular speed change depends on the starting and ending frequencies.
SJ300 Inverter 1–17 Q. What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? A. Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier” to describe the electronic unit that controls a motor. What does “inverter” mean? A. Q. A specific inverter model is set at the factory to work across a voltage range particular to the destination country for that model.
1–18 Frequently Asked Questions Q. What type of motor is compatible with the Hitachi inverters? Geting Started A. Motor type – It must be a three phase AC induction motor. Use an inverter-grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class. Motor size – In practice, it’s better to find the right size motor for your application; then look for the inverter to match the motor.

2–18 Step-by-Step Basic Installation 6 Inverter Mounting and Installation Wire the Inverter Input to a Supply Step 6: In this step, you will connect wiring to the input of the inverter. All models have the same power connector terminals [R(L1)], [S(L2)], and [T(L3)] for three-phase input. The three phases may be connected in any order, as they are isolated from chassis ground and do not determine motor direction of rotation.
SJ300 Inverter 2–19 NOTE: An inverter powered by a portable or emergency diesel power generator may result in a distorted power waveform, overheating the generator. In general, the generator capacity should be at least five times that of the inverter (kVA). CAUTION: Be sure that the input voltage matches the inverter specifications: • Three phase 200 to 240V 50/60Hz • Three phase 380 to 480V 50/60Hz CAUTION: Be sure not to connect an AC power supply to the output terminals.
2–20 Step-by-Step Basic Installation 7 Wire the Inverter Output to Motor Step 7: The process of motor selection is beyond the scope of this manual. However, it must be a three-phase AC induction motor. It should also come with a chassis ground lug. If the motor does not have three power input leads, stop the installation and verify the motor type. Other guidelines for wiring the motor include: • Use an inverter-grade motor for maximum motor life (1600V insulation).

3–2 Choosing a Programming Device Choosing a Programming Device Introduction Hitachi variable frequency drives (inverters) use the latest electronics technology for getting the right AC waveform to the motor at the right time. The benefits are many, including energy savings and higher machine output or productivity. The flexibility required to handle a broad range of applications has required ever more configurable options and parameters—inverters are now a complex industrial automation component.

3–5 SJ300 Inverter Operational Modes The RUN and PGM LEDs tell just part of the story; Run Mode and Program Modes are independent modes, not opposite modes. In the state diagram to the right, Run alternates with Stop, and Program Mode alternates with Monitor Mode. This is a very important ability, for it shows that a technician can approach a running machine and change some parameters without shutting down the machine.

3–9 SJ300 Inverter “A” Group: Standard Functions Basic Parameter Settings These settings affect the most fundamental behavior of the inverter—the outputs to the motor. The frequency of the inverter’s AC output determines the motor speed. You may select from three different sources for the reference speed.

SJ300 Inverter Multi-speed and Jog Frequency Settings 3–13 The SJ300 inverter has the capability to store and output up to 16 preset frequencies to the motor (A020 to A035). As in traditional motion terminology, we call this multi-speed profile capability. These preset frequencies are selected by means of digital inputs to the inverter. The inverter applies the current acceleration or deceleration setting to change from the current output frequency to the new one.
3–14 “A” Group: Standard Functions Torque Control Algorithms The inverter generates the motor output according to the V/f algorithm or the sensorless vector control algorithm. Parameter A044 selects the inverter torque control algorithm for generating the frequency output, as shown in the diagram to the right (A244 and A344 for 2nd and 3rd motors, respectively). The factory default is 00 (constant torque V/f control).
SJ300 Inverter 3–15 c. After reaching the base frequency, the characteristic maintains a constant output voltage for higher frequencies. Using parameter A045 you can modify the voltage gain of the inverter. This is specified as a percentage of the full-scale setting AVR (Automatic Voltage Regulation) in parameter A082. The gain can be set from 20% to 100%. It must be adjusted in accordance with the motor specifications.
3–16 “A” Group: Standard Functions The V/f free-setting endpoint f7/V7 parameters must stay within the more basic inverter limits in order for the specified free-setting characteristic curve to be achieved. For example, the inverter cannot output a higher voltage than the input voltage or the AVR setting voltage (Automatic Voltage Regulation), set by parameter A082. The graph to the right shows how the inverter input voltage would clip (limit) the characteristic curve if exceeded.

The current frequency command serves as the SP. The PID loop algorithm will read the analog input for the process variable (you specify either current or voltage input) and calculate the output.
SJ300 Inverter Automatic Voltage Regulation (AVR) Function The automatic voltage regulation (AVR) feature keeps the inverter output voltage at a relatively constant amplitude during power input fluctuations. This can be useful if the installation is subject to input voltage disturbances. However, the inverter cannot boost its motor output to a voltage higher than the power input voltage. If you enable this feature, be sure to select the proper voltage class setting for your motor. “A” Function Func.

The inverter CPU can also calculate other curves shown in the graphs below. The sigmoid, U-shape, and reverse U-shape curves are useful for favoring the load characteristics in particular applications. Curve settings for acceleration and deceleration are independently selected via parameters A097 and A098, respectively.
SJ300 Inverter 3–27 The acceleration and deceleration curves can deviate from a straight line to a varying degree. Parameters A131 and A132 control the amount of deviation for the acceleration and deceleration curves respectively.

If under-voltage exists longer than this time, the inverter trips, even if the restart mode is selected. If it exists less than this time retry will be attempted.
3–31 SJ300 Inverter The torque developed in a motor is directly proportional to the current in the windings, which is also proportional to the heat generated (and temperature, over time). Therefore, you must set the thermal overload threshold in terms of current (amperes) with parameter B012. The range is 50% to 120% of the rated current for each inverter model. If the current exceeds the level you specify, the inverter will trip and log an event (error E5) in the history table.

This feature provides quick access for the most-used functions needed for your application. Each U Group function can serve as a pointer to any of the other parameters.
3–68 Programming Error Codes Programming Error Codes The SJ300 inverter operator keypad displays a special code (begins with the character) to indicate a programming error. Programming errors exist when one parameter conflicts with the meaningful range permitted by related parameter(s). Note that particular real-time frequency (speed) input levels can cause a conflict in some situations. After a conflict exists, the error code will appear on the display, or you can view it later with D090 in Monitor Mode.

4–2 Introduction Introduction The previous material in Chapter 3 gave a reference listing of all the programmable functions of the inverter. We suggest that you first scan through the listing of inverter functions to gain a general familiarity. This chapter will build on that knowledge in the following ways: 1. Related functions – Some parameters interact with or depend on the settings in other functions.
SJ300 Inverter Warnings for Operating Procedures 4–3 Before continuing, please read the following Warning messages. WARNING: Be sure to turn ON the input power supply only after closing the front case. While the inverter is energized, be sure not to open the front case. Otherwise, there is the danger of electric shock. WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise, there is the danger of electric shock.
4–4 Optional Controlled Decel and Alarm at Power Loss Optional Controlled Decel and Alarm at Power Loss With the default SJ300 inverter configuration, a sudden power loss will cause the inverter to shut down immediately. If running at the time, the motor and load will coast to a stop. And without power, the inverter’s alarm output will not activate. This default performance may be fine for applications with loads such as fans and pumps.
SJ300 Inverter 4–5 Follow the steps to implement the wiring change shown in the previous diagram. 1. Remove the 2-wire jumper J51 (terminals [R0] and [T0] to connector J51). 2. Procure several inches of multi-strand 20 AWG (0.5mm2) or slightly heavier wire. 3. Connect a wire to terminal [R0] that is long enough to connect to terminal [P] (do not connect to [P] yet). 4. Connect a wire to terminal [T0] that is long enough to connect to terminal [N] (do not connect to [N] yet). 5.
4–6 Optional Controlled Decel and Alarm at Power Loss The timing diagram below shows a power loss scenario and the related parameter settings. During the controlled deceleration the inverter itself acts as a load to decelerate the motor. With either a high-inertia load or a short deceleration time (or both), it is possible that the inverter impedance will not be low enough to continue linear deceleration and avoid an over-voltage condition on the DC bus.
4–7 SJ300 Inverter Connecting to PLCs and Other Devices Hitachi inverters (drives) are useful in many types of applications. During installation, the inverter keypad (or other programming device) will facilitate the initial configuration. After installation, the inverter will generally receive its control commands through the control logic terminals or serial interface from another controlling device.
4–8 Connecting to PLCs and Other Devices Example Wiring Diagram The schematic diagram below provides a general example of logic connector wiring, in addition to basic power and motor wiring covered in Chapter 2. The goal of this chapter is to help you determine the proper connections for the various terminals shown below for your specific application needs.
SJ300 Inverter 4–9 Specifications of The control logic connector board is removable for wiring convenience as shown below (first, Control and Logic remove two retaining screws). The small connector to the left is for serial communications.
4–10 Connecting to PLCs and Other Devices Terminal Listing Use the following table to locate pages for intelligent input and output material in this chapter. Operations and Monitoring Intelligent INPUTS Symbol Code Name Intelligent OUTPUTS Page Symbol Code Name Page RV 01 Reverse Run/Stop 4–12 RUN 00 Run signal 4–43 CF1 02 Multi-speed select, Bit 0 (LSB) 4–13 FA1 01 4–44 CF2 03 Multi-speed select, Bit 1 4–13 Freq.
4–11 SJ300 Inverter Using Intelligent Input Terminals Intelligent terminals [1], [2], [3], [4], [5], [6], [7], and [8] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply (P24) to power the inputs. The input circuits connect internally to [PLC] as a common point. To use the internal supply to power the inputs, use the jumper as shown.
4–12 Using Intelligent Input Terminals Wiring Diagram Conventions The input wiring diagrams in this chapter are examples only. Default and non-default input terminal assignments are noted throughout; your particular assignments may be different. The wiring diagrams show the –xFU/–xFR model default [P24]–[PLC] jumper position (U.S./Jpn versions), as shown below on the left. The common (return) for inputs is [CM1] in this case.
4–13 SJ300 Inverter Multi-Speed Select The inverter can store up to 16 different fixed target frequencies (speeds) in parameters A020 to A035. Binary inputs select the speed through four of the intelligent terminals configured as binary-encoded inputs CF1 to CF4 per the table. These can be any of the eight inputs, and in any order. You can use fewer inputs if you need eight or fewer speeds.
4–14 Using Intelligent Input Terminals Opt.
SJ300 Inverter 4–15 The Bit Operation method of speed control uses up to seven intelligent inputs to select from up to eight speeds. Since the all-switches-OFF combination selects the first speed, you only need N-1 switches to select N speeds. With Bit Operation speed control, only one input is normally active at a time. If multiple switches are ON, the lower numbered input takes precedence (determines the speed). The table and figure below show how the input combinations work.
4–16 Using Intelligent Input Terminals Jogging Command The Jog input [JG] is used to command the motor to rotate slowly in small increments for manual operation. The speed is limited to 10 Hz. The frequency for the jogging operation is set by parameter A038. Jogging does not use an acceleration ramp. Therefore setting the jogging frequency A038 too high will cause inverter tripping. [JG] [FW] [RV] A038 A jog command may arrive while the motor Output t is running.
SJ300 Inverter External Signal for DC Injection Braking When the terminal [DB] is turned ON, the DC braking [DB] feature is enabled. Set the following parameters when the external DC braking terminal is to be used: Scenario 1 [FW, RV] • A053 – DC braking delay time setting. The range 0.0 to 5.0 seconds. [DB] • A054 – DC braking force setting. The range is 0 to 100%. Output frequency t The scenarios to the right help show how DC braking works in various situations. Scenario 2 1.
4–18 Using Intelligent Input Terminals Set Second or Third Motors If you assign the [SET] or [SET3] functions to an intelligent input terminal, you can select between two or three sets of motor parameters. You may assign one or both of these functions. These second and third parameters store alternate sets of motor characteristics. When terminal [SET] or [SET3] is turned ON, the inverter will use the second or third set of parameters accordingly, generating the frequency output to the motor.
4–19 SJ300 Inverter Two-stage When terminal [2CH] is turned ON, the Acceleration and inverter changes the rate of acceleration and deceleration from the initial settings (F002 Deceleration Output frequency and F003) to use the second set of acceleration/deceleration values. When the terminal is turned OFF, the inverter is returned to the original acceleration and deceleration time (F002 acceleration time 1, and F003 deceleration time 1).
4–20 Using Intelligent Input Terminals Free-run Stop When the terminal [FRS] is turned ON, the inverter turns OFF the output and the motor enters the free-run state (coasting). If terminal [FRS] is turned OFF, the output resumes sending power to the motor if the Run command is still active. The free-run stop feature works with other parameters to provide flexibility in stopping and starting motor rotation.
SJ300 Inverter External Trip 4–21 When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output. This is a general purpose interrupt type feature, and the meaning of the error depends on what you connect to the [EXT] terminal. Even if [EXT] is turned OFF, the inverter remains in the trip state. You must reset the inverter or cycle power to clear the error, returning the inverter to the Stop Mode.
4–22 Using Intelligent Input Terminals Unattended Start If the Run command is already present when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that Protection automatic startup, so that the inverter will not run without outside intervention. When USP is active, there are two ways to reset an alarm and resume running: 1. Turn the Run command OFF, or 2.
SJ300 Inverter Commercial Power Source Switching 4–23 The commercial power source switching function is useful in systems with excessive starting torque requirements. This feature permits the motor to be started “across the line,” sometimes called a bypass configuration. After the motor is running, the inverter takes over to control the speed. This feature can eliminate the need to oversize the inverter, reducing cost.
4–24 Using Intelligent Input Terminals In the previous timing diagram, when the motor has been started across the line, Mg2 is switched OFF and Mg3 is switched ON. With the Forward command to the inverter already ON, the [CS] terminal is switched ON and relay Mg1 contacts close. The inverter will then read the motor RPM (frequency matching). When the [CS] terminal is switched OFF, the inverter applies the Retry wait time before motor restart parameter (B003).
SJ300 Inverter Software Lock 4–25 When the terminal [SFT] is turned ON, the data of all the parameters and functions (except the output frequency, depending on the setting of B031) is locked (prohibited from editing). When the data is locked, the keypad keys cannot edit inverter parameters. To edit parameters again, turn OFF the [SFT] terminal input. Use parameter B031 to select whether the output frequency is excluded from the lock state or is locked as well. Opt.
4–26 Using Intelligent Input Terminals Operations and Monitoring Analog Input Current/Voltage Select The [AT] terminal operates in conjunction with parameter setting A005 to determine the analog input terminals that are enabled for current or voltage input. Setting A006 determines whether the signal will be bipolar, allowing for a reverse direction range. Note that current input signal cannot be bipolar and cannot reverse direction (must use [FW] and [RV] command with current input operation).
4–27 SJ300 Inverter Reset Inverter The [RS] terminal causes the inverter to execute the reset operation. If the inverter is in Trip Mode, the reset cancels the Trip state. When the signal [RS] is turned ON and OFF, the inverter executes the reset operation. The minimum pulse width for [RS] must be 12 ms or greater. The alarm output will be cleared within 30 ms after the onset of the Reset command. 12 ms minimum [RS] approx.
4–28 Using Intelligent Input Terminals Thermistor Thermal Protection Motors that are equipped with a thermistor can be protected from overheating. Input terminal [TH] is dedicated to sense a thermistor resistance. The input can be set up (via B098 and B099) to accept a wide variety of NTC or PTC type thermistors. Use this function to protect the motor from overheating. Opt.
SJ300 Inverter Three-wire Interface Operation 4–29 The 3-wire interface is an industry standard motor control interface. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21 [STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals. Use momentary contact for Start and Stop.
4–30 Using Intelligent Input Terminals PID ON/OFF and PID Clear The PID loop function is useful for controlling motor speed to achieve constant flow, pressure, temperature, etc. in many process applications. The PID Disable function temporarily suspends PID loop execution via an intelligent input terminal. It overrides the parameter A071 (PID Enable) to stop PID execution and return to normal motor frequency output characteristics. the use of PID Disable on an intelligent input terminal is optional.
SJ300 Inverter Internal Speed Loop Gain Settings 4–31 When sensorless vector control, 0Hz sensorless vector control, or vector control with sensor is selected for the control method, the Control Gain Switching function selects between two sets of gains in the internal speed loop. These gains are used in proportional and integral compensation. Use option code 26 to assign the [CAS] function to an intelligent input terminal. Use option code 43 to select between P and PI control. Opt.
4–32 Using Intelligent Input Terminals The speed control mode is normally proportionalintegral compensation (PI), which attempts to keep the deviation between the actual speed and speed command equal to zero. You can also select proportional (P) control function, which can be used for droop control (i.e. several inverters driving one load). Droop is the speed difference resulting from P control versus PI control at 100% output torque as shown in the graph.
4–33 SJ300 Inverter Remote Control Up and Down Functions The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time used with this function is the same as for normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate as follows: • Acceleration - When the [UP] contact is turned ON, the output frequency accelerates from the current value.
4–34 Using Intelligent Input Terminals Operations and Monitoring Force Operation from Digital Operator This function permits a digital operator interface to override the Run command source setting (A002) when it is configured for a source other than the operator interface. When the [OPE] terminal is ON and the operator interface gives a Run command, the inverter uses the standard output frequency settings to operate the motor. Opt.
SJ300 Inverter Overload Restriction 4–35 The inverter constantly monitors the motor current during acceleration, deceleration, and constant speed. If the inverter reaches the overload restriction level, it adjusts the output frequency automatically to limit the amount of overload. This function prevents an over-current trip by inertia during rapid acceleration or large changes in load at constant speed. It also attempts to prevent an over-voltage trip on deceleration due to regeneration.
4–36 Using Intelligent Input Terminals The figure below shows the operation during an overload restriction event. The overload restriction level is set by B022 and B025. The overload restriction constant is the time to decelerate to 0Hz from maximum frequency. When this function operates, the acceleration time will be longer than the normal acceleration time.
SJ300 Inverter Torque Limit 4–37 The Torque Limit function limits the motor output torque for sensorless vector control, sensorless vector control 0Hz domain, or vector control with feedback. In the torque limit function, the following operational modes are available (selected by B040): 1. Four-quadrant individual setting mode – This mode sets torque limit in 4 zones, forward driving and regenerating, reverse driving and regenerating. Limits for each quadrant are set with B041 – B044 individually. 2.
4–38 Using Intelligent Input Terminals The 4-quadrant operation mode for torque limiting (B040=00) is illustrated in the figure to the right. The instantaneous torque depends on inverter activity (acceleration, constant speed, or deceleration), as well as the load. These factors determine the operating quadrant at any particular time. The parameters in B041, B042, B043 and B044 determine the amount of torque limiting that the inverter applies.
SJ300 Inverter 4–39 External Brake The External Brake Control function enables the inverter to control external electromechanical Control Function brake systems with a particular safety characteristic. For example, elevator control systems maintain the brake on the load until the drive motor has reached a releasing frequency (point at which the external mechanical brake is released). This ensures that the load does not have an opportunity to begin coasting before the inverter begins driving the motor.
4–40 Using Intelligent Input Terminals Code Function Data or Range Description B123 Brake wait time for stopping 0.00 to 5.00 sec. Sets the time delay after brake confirmation signal [BOK] turns OFF (after [BRK] turns OFF) until decelerating the inverter to 0 Hz B124 Brake wait time for confirmation 0.00 to 5.00 sec. Sets the wait time for [BOK] signal after turn ON/ OFF of [BRK] signal.
SJ300 Inverter Expansion Card Input Signals 4–41 Other inputs listed below require the expansion card SJ-FB Encoder Feedback. Please see the SJ-FB manual for more information. Opt.
4–42 Using Intelligent Output Terminals Using Intelligent Output Terminals The intelligent output terminals are programmable in a similar way to the intelligent input terminals. The inverter has several output functions that you can assign individually to five physical logic outputs. Along with these solid-state outputs, the alarm relay output has type Form C (normally open and normally closed) contacts.
4–43 SJ300 Inverter Run Signal When the [RUN] signal is selected as an intelligent output terminal, the inverter outputs a signal on that terminal when it is in Run Mode. The output logic is active low, and is the open collector type (switch to common). [FW, RV] Motor speed start freq. B82 Run Signal ON t Opt.
4–44 Using Intelligent Output Terminals Frequency Arrival The Frequency Arrival group of outputs help coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output Signals frequency arrives at the standard set frequency (parameter F001). Outputs [FA2] through [FA5] provide variations on this function for increased flexibility, relying on two programmable accel/ decel thresholds.
SJ300 Inverter Frequency arrival output [FA1] uses the standard output frequency (parameter F001) as the threshold for switching. In the figure to the right, the inverter accelerates to the set output frequency, which serves as the threshold for [FA1]. Parameters Fon and Foff illustrate the hysteresis that prevents output chatter near the threshold value. Output frequency Hz Foff Fon Threshold F001 • Fon is 1% of the max. output frequency 0 t • Foff is 2% of the max.
4–46 Using Intelligent Output Terminals Overload Advance Notice Signal When the output current exceeds a preset value, the [OL] or [OL2] terminal signal turns ON. The parameter C041 (or C111, respectively) sets the overload threshold. The overload detection circuit operates during powered motor operation and during regenerative braking. The output circuits use open-collector transistors, and are active low.
4–47 SJ300 Inverter Output Deviation The PID loop error is defined as the magnitude (absolute value) of the differfor PID Control ence between the Setpoint (target value) and the Process Variable (actual value). When the error magnitude exceeds the preset value for C044, the [OD] terminal signal turns ON. Refer to “PID Loop Operation” on page 4–71. Error (SP-PV) Set value Process variable Setpoint C044 C044 [OD] Signal ON ON t Opt.
4–48 Using Intelligent Output Terminals Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactive. Run STOP RESET Stop RUN Operations and Monitoring We must make a distinction between the alarm STOP RESET signal AL and the alarm relay contacts [AL0], Fault [AL1] and [AL2].
SJ300 Inverter 4–49 The alarm output terminals operate as shown below (left) by default. The contact logic can be inverted as shown (below right) by using the parameter setting C036. The relay contacts normally open (N.O.) and normally closed (N.O.) convention uses “normal” to mean the inverter has power and is in Run or Stop Mode. The relay contacts switch to the opposite position when it is in Trip Mode or when input power is OFF.
4–50 Using Intelligent Output Terminals Over-torque Signal The Over-torque function [OTQ] turns ON when the estimated value of output torque of motor increases more than the arbitrary level set for the output. Recall that the torque limit function, covered in “Torque Limit” on page 4–37, actually limits the torque during certain operating conditions. Instead, the over-torque output feature only monitors the torque, turning ON output [OTQ] if the torque is above programmable thresholds you set.
SJ300 Inverter Instantaneous Power Failure / Under-voltage Signal 4–51 An instantaneous power failure (complete loss) or under-voltage condition (partial loss) of inverter input voltage can occur without warning. SJ300 Series inverters can be configured to respond to these conditions in different ways. You can select whether the inverter trips or retries (restart attempt) when an instantaneous power failure or under-voltage condition occurs. You can select the retry function with parameter B001.
4–52 Using Intelligent Output Terminals Opt.
SJ300 Inverter 4–53 Examples 3 and 4 relate to configuring the inverter to retry upon power failure. Frequency matching is possible if the inverter frequency is greater than the B007 value.
4–54 Using Intelligent Output Terminals Torque Limit Signal The Torque Limit output [TRQ] works in conjunction with the torque limit function covered in the intelligent input section. The torque limit function limits the motor torque according to the criteria selected by parameter B040. When torque limiting occurs, the [TRQ] output turns ON, then going OFF automatically when the output torque falls below the specified limits. See “Torque Limit” on page 4–37 in the intelligent input section. Opt.

Code Symbol Function Name Valid for outputs: 11, 12, 13, 14, 15, AL0 – AL2 Required settings: B034 Output State Description Example: (Requires output configuration— see page 3–53.) Inverter output terminal circuit Notes: • The two outputs [RNT] and [ONT] share the same time threshold parameter, B040. Typically, you will use either the [RNT] or the [ONT] output only—not both at once.

4–58 Using Intelligent Output Terminals Brake Control Signals The Brake Control function enables the inverter to control external braking systems with a particular safety characteristic. A complete discussion of the operation of brake control is in “External Brake Control Function” on page 4–39. The block diagram and table that follow describe the configuration of the outputs [BRK] Brake Release and [BER] Brake Error.
SJ300 Inverter 4–59 Analog Input Operation Input Terminal Signals The SJ300 inverters provide for an external analog input to command the inverter frequency output value. The analog input terminal group includes the [L], [OI], [O], [O2], and [H] terminals on the control connector, which provide for Voltage [O] and [O2] or Current [OI] input. All analog input signals must use the analog ground [L]. H O2 AM FM L O OI AMI A GND +V Ref.
4–60 Analog Input Operation The following tables show the available analog input settings. Parameters A006, A005, and input terminal [AT] determine the External Frequency Command input terminals that are available and how they function. The Trim Frequency input [O2]—[L] is available (when check marked) for some settings. Other settings make the reverse direction (in addition to forward) available for bipolar input settings (when check marked).
SJ300 Inverter 4–61 The examples below show how the use of the [AT] input during operation enables/disables the Trim Frequency Command input [O2]—[L]. The [O2]—[L] input may be used alone, or as an offset control for the primary analog input.
4–62 Analog Output Operation Analog Output Operation In the system design for inverter applications it is sometimes useful to monitor inverter operation from a remote location. In some cases, this requires only a panel-mounted analog meter (moving-coil type). In other cases, a controller device such as a PLC may monitor and command the inverter frequency and other functions.
4–63 SJ300 Inverter To calibrate the meter reading, generate a full-scale output (always ON) at terminal [FM]. Then use parameter B081(gain setting from 0 to 255) to adjust the corresponding full-scale reading of the meter. For example, when the inverter output frequency is 60 Hz, change the value of B081 so that the meter reads 60 Hz. TIP: When using the analog meter for monitoring, adjust the meter so it has a zero reading when the [FM] output is zero.
4–64 Analog Output Operation [AM] and [AMI] Terminals The [AM] and [AMI] terminals provide signals to monitor various inverter parameters such as output frequency, output current, and torque. The terminals provide these analog signal types: L O OI AMI • [AM] terminal: 0–10V analog output signal A GND • [AMI] terminal: 4–20mA analog output signal 0–10V analog output These signals both use the [L] terminal for signal return.
SJ300 Inverter 4–65 Setting Motor Constants for Vector Control Introduction These advanced torque control algorithms improve performance, particularly at low speeds: • Sensorless Vector Control – improved torque control at output frequencies down to 0.5 Hz. Use A044=03 (1st motor) or A244=03 (2nd motor) to select sensorless vector control. • Sensorless Vector Control, 0Hz Domain – improved torque control at output frequencies from 0 to 2.5 Hz.
4–66 Setting Motor Constants for Vector Control Func. Name Data Notes H031 Auto-tuned constant R2, 1st motor 0.000–65.53 Units: ohms H032 Auto-tuned constant L, 1st motor 0.00–655.3 Units: mH H033 Auto-tuned constant Io, 1st motor 0.00–655.3 Units: A H034 Auto-tuned constant J, 1st motor 0.001–9999 Units: kgm2 The inverter has three separate motor constant sets named 1st, 2nd, and 3rd.
SJ300 Inverter Auto-tuning of Motor Constants 4–67 The SJ300 inverter features auto-tuning, which detects and records the motor characteristic parameters to use in all vector control modes. Auto-tuning determines the resistance and inductance of motor windings. Therefore, the motor must be connected to the inverter for this procedure. Note that the auto-tuning feature is not associated with PID loop operation, which is common on some control devices.
4–68 Setting Motor Constants for Vector Control Preparation for Auto-tuning Procedure – Be sure to study the preparation items and verify the related inverter configuration before going further in this procedure. 1. Adjust the motor base frequency (A003) and the motor voltage selection (A082) to match the specifications of the motor used in the auto-tuning procedure. 2. Verify that the motor is not more than one frame size smaller than the rated size for he inverter.
SJ300 Inverter 4–69 If the auto-tuning procedure is successful, the inverter updates the motor characteristic parameters and indicates normal termination of the procedure as shown. Pressing any key on the keypad will clear the result from the display. • Trip during auto-tuning – A trip event will cause the autotuning sequence to quit. The display will show the error code for the trip rather than the abnormal termination indication.
4–70 Setting Motor Constants for Vector Control Manual Setting of With vector control, the inverter uses the output current, output voltage, and motor constants to Motor Constants estimate the motor torque and speed. It is possible to achieve a high starting torque and accurate speed control at low frequency • Sensorless Vector Control – improved torque control at output frequencies down to 0.5 Hz. Use A044=03 (1st motor) or A244=03 (2nd motor) to select sensorless vector control.
SJ300 Inverter 4–71 PID Loop Operation In standard operation, the inverter uses a reference source selected by parameter A001 for the output frequency, which may be a fixed value (F001), a variable set by the front panel potentiometer, or value from an analog input (voltage or current). To enable PID operation, set A071 = 01. This causes the inverter to calculate the target frequency, or setpoint.
4–72 Configuring the Inverter for Multiple Motors Configuring the Inverter for Multiple Motors Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single inverter’s output. For example, this is common in conveyor applications where two separate conveyors need to have approximately the same speed. The use of two motors may be less expensive than making the mechanical link for one motor to drive multiple conveyors.
SJ300 Inverter 4–73 Parameters for the second motor and third motors have function codes of the form x2xx and x3xx respectively. They appear immediately after the first motor’s parameter in the menu listing order. The following table lists the parameters that have the second/third parameter registers for programming.

5–2 Introduction Introduction A motor speed control system will obviously include a motor and inverter, as well as fuses for safety. If you are connecting a motor to the inverter on a test bench just to get started, that’s all you may need for now. But a fully developed system can also have a variety of additional components. Some can be for noise suppression, while others may enhance the inverter’s braking performance.
SJ300 Inverter 5–3 Component Descriptions AC Reactors, Input Side This is useful in suppressing harmonics induced on the power supply lines, or when the main power voltage imbalance exceeds 3% (and power source capacity is more than 500 kVA), or to smooth out line fluctuations. It also improves the power factor.
5–4 Component Descriptions Zero-phase Reactor (RF Noise Filter) EMI Filter Electrical noise interference may occur on nearby equipment such as a radio receiver. The zero-phase reactor helps reduce radiated noise from the inverter wiring. It can be used on the input or output side of the inverter. The example zero-phase reactor shown to the right comes with a mounting bracket. The wiring must go through the opening to reduce the RF component of the electrical noise.
SJ300 Inverter Expansion Cards The SJ–FB Encoder Feedback Board installs in the inverter’s expansion bay, which can accept up to two expansion cards.
