Software overcurrent
AC drive
Meaning:
Possible causes
- The software overcurrent detection threshold A4-18 is set incorrectly.
- The control mode is FVC or SVC, and the speed loop parameter settings are too aggressive.
- Control mode is FVC or SVC, and the synchronous motor is demagnetized
- Control mode is FVC or SVC, and motor parameters have not been identified
- Carrier frequency setting too low for high-speed operation
- Starting directly before the motor has completely stopped rotating
- The control mode is V/f; oscillation causes overcurrent.
- The control mode is V/f, and the overcurrent suppression parameter settings are inappropriate.
- The control mode is V/f, and the overvoltage suppression or undervoltage suppression parameters are inappropriate.
- The control mode is V/f, and the torque boost parameter setting is too large.
- Acceleration/deceleration time too short in V/f control
- Model parameter setting error
- Motor parameter setting error
- V/f curve reference voltage too large in V/f control
- Unstable operation near 0Hz in SVC control
- The custom software overcurrent detection threshold [A4-38] is low.
- Control mode is FVC, and encoder parameter settings are inappropriate
- Control mode is FVC, and encoder wiring has an error
- Control mode is FVC, and the encoder-related parameters have not been identified
- Control mode is FVC, and there is a problem with encoder installation
- Control mode is FVC, and the synchronous motor position changes after stop
- External equipment error
