Inovance E043.1 fault code meaning
Inovance / E043.1
Series: MD520
Motor overspeed fault
AC drive
Meaning: A motor overspeed fault is reported when the deviation between the estimated frequency and the actual output frequency exceeds 15% rated frequency for longer than the detection time threshold (default: 1.0s; adjustable via parameter F9-68).
Possible causes
- Incorrect encoder parameter settings
- Auto-tuning has not been performed
- Incorrect synchronous motor encoder zero point angle causes runaway.
- Motor overspeed detection parameters F9-67 and F9-68 are set inappropriately.
