Inovance 2-1 fault code meaning

Series: MD580

AC drive

Meaning: Fault category: Overcurrent; Default level: Coast to stop; Reset method: Manual reset

Ground fault or short circuit in the output circuit of drive UVW, or short circuit in the braking resistor
The motor is started in FVC or SVC control mode without performing auto-tuning.

AC drive

Meaning:

Ground fault or short circuit in the output circuit of drive UVW, or short circuit in the braking resistor
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
Direct start while the motor is still rotating
The control mode is V/f; oscillation causes overcurrent.
The control mode is V/f, and the overcurrent suppression parameter settings are inappropriate.
Overvoltage suppression or undervoltage suppression parameter settings 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 software overcurrent detection threshold A4-18 is set incorrectly.
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
