Possible causes
- The selected drive is undersized.
- There is a ground fault or short circuit in the drive output circuit.
- The motor is started in FVC or SVC control mode without performing auto-tuning.
- Acceleration/deceleration time is set too short for rapid acceleration and deceleration.
- The manual torque boost setting is unsuitable; the V/f curve is unsuitable.
- The motor is started while it is rotating.
- FVC encoder feedback signal error during run.
- The motor cable is too long.
- The DC bus voltage is low.
- The motor parameter settings are incorrect.
