Warranty Summary
No warranty information found in the manual.
This quick start manual provides essential information for the installation and operation of CG Emotron VS Series DC Drives. Key steps include safety precautions (Chapter 1), product information and features (Chapter 2), and detailed installation and wiring instructions (Chapter 3). The manual covers keypad operation (Chapter 4), parameter lists (Chapter 5), and parameter specifications (Chapter 6). Commissioning guides for solar and elevator applications are included in Chapters 7 and 8 respectively, followed by maintenance and troubleshooting guidelines in Chapter 9. Appendices provide MODBUS communication protocol and braking resistor details.
Troubleshooting and error codes
| Display | Fault Name | Possible Causes | Solutions |
|---|---|---|---|
| Err01 | Accel overcurrent | 1: The output circuit is grounded or short circuited. 2: The acceleration time is too short. 3: Manual torque boost or V/F curve is not appropriate. 4: The voltage is too low. 5: The startup operation is performed on the rotating motor. 6: A sudden load is added during acceleration. 7: The AC drive model is of too small power class. | 1: Eliminate external faults. 2: Increase the acceleration time. 3: Adjust the manual torque boost or V/F curve. 4: Adjust the voltage to normal range. 5: Select rotational speed tracking restart or start the motor after it stops. 6: Remove the added load. 7: Select an AC drive of higher power class |
| Err02 | Decel overcurrent | 1: The output circuit is grounded or short circuited. 2: The deceleration time is too short. 3: The voltage is too low. 4: A sudden load is added during deceleration. 5: The braking unit and braking resistor are not installed. | 1: Eliminate external faults. 2: Increase the deceleration time. 3: Adjust the voltage to normal range. 4: Remove the added load. 5: Install the braking unit and braking resistor. |
| Err03 | Constant-speed overcurrent | 1: The output circuit is grounded or short circuited. 2: The voltage is too low. 3: A sudden load is added during operation. 4: The AC drive model is of too small power class. | 1: Eliminate external faults 2: Adjust the voltage to normal range. 3: Remove the added load 4: Select an AC drive of higher power class. |
| Err04 | Accel overvoltage | 1: The input voltage is too high. 2: An external force drives the motor during acceleration. 3: The acceleration time is too short. 4: The braking unit and braking resistor are not installed. | 1: Adjust the voltage to normal range. 2: Cancel the external force or install a braking resistor. 3: Increase the acceleration time. 4: Install the braking unit and braking resistor. |
