FAQ and Troubleshooting

Q: Can this drive run a standard induction motor without an encoder?

• A: Yes. You can use it in V/F or Sensorless Vector control mode without a PG (encoder).

Q: Is an external braking resistor required?

• A: The drive has a built-in brake chopper, but you must connect an external braking resistor to it for energy dissipation during rapid stops.

Q: What is the first step after installing the drive?

• A: Always perform motor parameter auto-tuning (with the motor disconnected from the load) for best performance in vector control modes.
