: If the drive is stuck and the alarm won't clear, try a factory reset and re-enter basic motor settings before attempting the "Run" command again.
: The motor will typically emit a whistling sound for a few seconds as it measures winding resistance and inductance. Completion
During commissioning, the inverter needs to measure the motor's electrical characteristics to ensure it runs efficiently and safely. Until it finishes this "handshake," it won't let the motor start. How to Resolve It
: After the alarm disappears, ensure you perform a Copy RAM to ROM (e.g., set p0971 = 1 ) to permanently save the new motor data, otherwise, the alarm may return after a power cycle. Common Troubleshooting Steps
The drive is receiving an active "OFF" command while you are trying to start the identification process.
