Chapter 4 Explanation of Functions 4.2.18 Torque boost setting Related code The torque boost setting function allows you to compensate for the voltage drop due to wiring and the primary resistance of the motor so as to improve the motor torque at low speeds. When you select automatic torque boost by the torque boost selection (A041/A241), adjust the settings of the motor capacity selection (H003/H203) and motor pole selection (H004/H204) based on the motor to be driven.
Chapter 4 Explanation of Functions (2) Automatic torque boost When automatic torque boost (data "01") is selected by the torque boost selection (A041/A241), the inverter automatically adjusts the output frequency and voltage according to the load on the motor. (During actual operation, the automatic torque boost is usually combined with the manual torque boost.
Chapter 4 Explanation of Functions 4.2.19 DC braking (DB) setting Related code The DC braking function allows you to apply DC braking to the motor according to the load on the motor. You can control DC braking in two ways: the external control through signal input to intelligent input terminals and the internal control to be performed automatically when the motor is started and stopped. Note that the motor cannot be stopped by DC braking if the load on the motor produces a large moment of inertia.
Chapter 4 Explanation of Functions (2) External DC braking Assign function "07" (DB) to terminal function (C001 to C008). Turn the DB terminal on and off to control the direct braking, regardless of the setting of DC braking enable (A051). Adjust the braking force by adjusting the DC braking force setting (A054). When you set the DC braking wait time (A053), the inverter output will be shut off for the set period of delay, and the motor will run freely during the period.
Chapter 4 Explanation of Functions (3) Internal DC braking (A051: 01) You can apply DC braking to the motor even without entering braking signals via the DB terminal when the inverter starts and stops. To use the internal DC braking function, specify "01" for the DC braking enable (A051).

Chapter 4 Explanation of Functions 4.3.16 Zero-return function (ORG, ORL) - One of three types of zero-return operations can be selected by zero-return mode selection (P068). When a zero-return operation ends, the current position counter is cleared (to 0). - Use zero-return direction selection (P069) to select the direction of zero-return operation. - If zero-return operation is not performed, position control is performed based on the assumption that the motor position detected at power-on is the origin.

Chapter 4 Explanation of Functions 4.4.
Chapter 4 Explanation of Functions The formats of the query and response frames are described below. Message configuration: Query Header (silent interval) Slave address Function code Data Error check code Trailer (silent interval) (i) Slave address The slave address is a number 1 to 32 that is assigned to the inverter (slave) beforehand. (A query is received by the inverter having the same slave address as that specified in the query.
Chapter 4 Explanation of Functions (iv) Error check code The Modbus-RTU protocol uses the cyclic redundancy check (CRC) as the error check method. The CRC code is the 16-bit data generated for a data block that has an arbitrary data length (in units of 8 bits). A generative polynomial for CRC-16 (X16 + X15 + X2 + 1) is used to generate the CRC code.
Chapter 4 Explanation of Functions Message configuration: Response (i) Time required for communication After the inverter receives a query, the inverter waits for the sum of the silent interval (corresponding to the transmission of 3.5 characters) and the communication wait time (C078) before sending a response. After receiving a response from the inverter, the master system must wait for the silent interval (corresponding to the transmission of 3.
Chapter 4 Explanation of Functions (4) Explanation of function codes (i) Reading the coil status [01h] This function reads the coil status (on or off). (Example) When reading the status of the intelligent input terminals [1] to [6] of the inverter at slave address "8": Assume that the intelligent input terminals are in the status as shown below.
Chapter 4 Explanation of Functions (ii) Reading registers [03h] This function reads a specified number of registers beginning at a specified register address.
Chapter 4 Explanation of Functions (iii) Writing data to a specified coil [05h] This function writes data to a specified coil The following table shows the updating of the coil status. Updating data (upper digit) Updating data (lower digit) Coil status OFF→ON ON→OFF FFh 00h 00h 00h (Example) When sending an operation command to the inverter at slave address "10": To start the inverter operation, "03" must be set in parameter "A002". Coil 1 is used to turn on an operation command.
Chapter 4 Explanation of Functions (v) Performing a loopback test [08h] The loopback test function is used to check the communication between the external control system (master) and the inverter (slave).
Chapter 4 Explanation of Functions (vii) Writing data to multiple registers [10h] This function writes data to sequential registers. (Example) When setting "3,000 Hz" as the Acceleration (1) time (F002) in the inverter at slave address "1": Since register "1103h" and "1104h" to store the Acceleration (1) time (F002) have a data resolution of 0.01 seconds, specify "300000" (493E0h) as the updating data to set "3,000 seconds".
Chapter 4 Explanation of Functions (5) Enter command (storing the updates of register data) Neither the command (06h) to write data to a register nor the command (10h) to write data to multiple registers can store the updates they made in the internal memory of the inverter. Turning the inverter power off without storing the updates deletes them and restores the original register settings.

Appendix Upgrading from the SJ300 Series The SJ300 series inverter is upwardly compatible with the SJ700 series inverter. Therefore, you can: - mount the control circuit terminal block board of the SJ300 series in the SJ700 series without removing the connected cables, - copy the parameter settings from the SJ300 series into the SJ700 series, and - use the option boards mounted in the SJ300 series for the SJ700 series without removing the connected cables.
Appendix (2) Copying the parameter settings If you use an optional remote operator (SRW-OJ or SRW-OEX), you can copy (import) the parameter settings from the SJ300 series into the SJ700 series. Note, however, that you cannot copy the parameter settings from the SJ700 series to the SJ300 series because the SJ700 series has many new functions and additional parameters.
