Inovance 10-3 fault code meaning

Series: MD880

Component overload

AC drive

Meaning:

Possible causes

• The load is too large.
• The selected drive is undersized.
• The model parameter settings are incorrect.
• The motor parameter settings are incorrect.
• The torque boost setting is inappropriate when the control mode is V/f.
• Motor locked rotor.
• The overload mode [A4-51] selection is inappropriate.
• The carrier frequency setting is too high, causing derating.
• Prolonged operation at low frequency causes derating.
• Operation becomes unstable near 0Hz when the control mode is SVC.
• The synchronous motor is demagnetized when the control mode is FVC or SVC.
• The motor parameters have not been identified when the control mode is FVC or SVC.
• The acceleration/deceleration time is too short when the control mode is V/f.
• The reference voltage of the V/f curve is too high when the control mode is V/f.
• The motor is started directly while it is still rotating.
• Oscillation causes overload when the control mode is V/f.
• The synchronous motor -603- magnetic pole angle identification is incorrect when the control mode is FVC or SVC.
• The encoder parameter settings are inappropriate when the control mode is FVC.
• There is an encoder wiring error when the control mode is FVC.
• The encoder-related parameters have not been identified when the control mode is FVC.
• There is a problem with the encoder installation when the control mode is FVC.
• The synchronous motor position changes after stopping when the control mode is FVC.
• Other causes.
