CHAPTER 6 Using the Keypad Factory-default parameter values allow the drive to be controlled from the integral keypad. No programming is required to start, stop, change direction, or control speed directly from the integral keypad. This chapter provides an overview of the integrated keypad and how to use it to program the VS1MD drive. 6.1 Keypad Components 1 2 3 4 Refer to table 6.1 for the LED descriptions noted by ➊ through ➍ and table 6.2 for key definitions. 6.1.
6.2 LED Descriptions Refer to figure 6.1 for the location of the LEDs described in table 6.1. Table 6.1 – LED Descriptions No. 6.3 LED ➊ PROG ➋ RUN ➌ FWD ➍ STP/FLT LED State Description Steady Red (On) Indicates the drive is in programming mode. (Off) Indicates the drive is in operational Mode. Steady Red (On) Indicates the drive is running at commanded speed. Flashing Red Indicates drive is accelerating or decelerating to new speed setting. (Off) Drive is not running.
Table 6.2 – Key Descriptions (Continued) Key Name Speed Reference Keys Description Operation Mode: • • Changes the commanded speed reference. • The Up-Arrow increases the speed reference at a controlled rate. • The Down-Arrow decreases the speed reference at a controlled rate. • Holding either arrow for a set period of time will increase the reference ramp rate. Only active when the input mode is programmed for keypad control.
Tunable parameters can be adjusted or changed while the drive is running or stopped. Read-only parameters cannot be adjusted. 6.5 How Parameters are Organized Parameters are organized into five Parameter Groups: • The Display Parameter Group (dnn) contains parameters for the display of basic drive information. • The Programming Parameter Group (Pnn) contains the most commonly used parameters for startup and operation.
Table 6.3 – Moving Between Parameter Groups Procedure Sample Display Step 5. Press the right arrow key to change to “Function Group 1”. Step 6. Press the right arrow key to change to “Function Group 2”. Step 7. Press the right arrow key to change to “Display” group. Step 8. Press and hold down the ENTER key for at least two seconds to change the drive from the programming mode back to operation mode.The “PROG” LED will go out indicating that the drive is in operation mode.
The below example indicates the steps needed to move from parameter F35 to Function Group 2. Table 6.4 – Moving from F35 to Function Group 2 Procedure Sample Display Step 1. When a parameter other than the first in a group is displayed, you must initially go to the first parameter of the group prior to going to the next group. For this example, parameter F35 of Function Group 1 is currently displayed and you want to go to Function Group 2 (H Parameters). Step 2.
The first parameter of each group, with the exception of the “Display Group”, is a special parameter called a “Jump Code”. The parameter can be used to jump to a specific parameter within a group without having to scroll through the parameters using the up and down arrows. Once the Jump Code is programmed, the drive will save the setting for future use, but this can always be reprogrammed to jump to a different parameter. The following example illustrates the use of a Jump Code to jump to parameter P38.
The following example shows how to use a previously stored Jump Code. Table 6.7 – Using a Previously Stored Jump Code Procedure Sample Display Step 1. From the operation mode, press and hold down the ENTER key for at least two seconds to change the drive to the programming mode. The “PROG” LED will illuminate indicating that the drive is in programming mode. The drive will display the first parameter of the “Display” group. Step 2. Press the right arrow to change to the “Parameters” group. Step 3.
The following example shows how to modify the acceleration time located in parameter P41. Table 6.8 – Modifying Parameter Values Program Group Step 1. From the operation mode, press and hold down the ENTER key for at least two seconds to change the drive to the programming mode. The “PROG” LED will illuminate indicating that the drive is in programming mode. The drive will display the first parameter of the “Display” group. Step 2. Press the right arrow key to change to the “Parameters” group. Step 3.
Table 6.8 – Modifying Parameter Values Step 9. Press the ENTER key to accept the value and the display will begin to flash so that you can confirm the entry. Step 10. Press the ENTER key a second time to acknowledge the entry. The display will revert to showing the parameter number. 6.9 Monitoring Display Parameters The Display group is a group that consists of read only values that can be monitored by the user to diagnose the operation of the drive and motor.
6.10 Reviewing the Fault Status in the Display Group When a fault is active, this is annunciated on the drive by flashing the STOP/FAULT LED. This procedure is used to review the active fault as well as certain conditions at the time the fault occurred. Table 6.10 – Reviewing Fault Status in the Display Group During Accel Overcurrent trip Current Frequency Display Group STOP RESET Step 1.
6.11 Resetting the Parameters to Factory Default Follow the below procedure to reset the parameters to the factory default values: Table 6.11 – Resetting Parameters to Factory Default Function Group 2 Step 1. Navigate to the Function Group 2 (H Group). Step 2. Press the ENTER key to edit the jump code. Modify the jump code to be equal to 93. Step 3. Press the ENTER key to jump to parameter H93. Step 4.

CHAPTER 9 Troubleshooting ! ATTENTION: This drive contains high voltage capacitors that take time to discharge after removal of mains supply. Before working on the drive, ensure isolation of mains supply from line inputs. Wait ten (10) minutes for capacitors to discharge to safe voltage levels. Failure to observe this precaution could result in severe bodily injury or loss of life.
9.2 Determining Drive Status Using the STP/FLT LED The STP/FLT LED can be used to determine at a quick glance the status of the drive. If the drive is stopped, but not faulted, this LED will be illuminated solid. If the drive is running, this LED will be off. If this LED is flashing, then this indicates that the drive is faulted thus requiring attention. Please refer to figure 9.1. 9.
If the application is using digital outputs to reflect the internal status of the drive, these can be monitored using parameter d8. The below describes the details of understanding the status of each of the digital outputs (labeled MO for the open collector output and 3A/3B/3C for the relay output on the control board terminal strip).
9.5.1 Manually Clearing Faults Step 1. Note the code of the fault condition on the display. Step 2. Address the condition that caused the fault. Refer to table 9.1 for a description of the fault and corrective actions. The cause must be corrected before the fault can be cleared. Step 3.
