Parameter Identification Fault

What does id1 mean?

The motor parameter identification process has failed, most likely because the motor is not properly connected to the drive. Incorrect parameter identification can lead to suboptimal motor control, instability, and potential damage to both the motor and the drive if not resolved.

• Motor not connected to the drive output terminals (U, V, W) or poor contact at these terminals.
• Motor phase cable discontinuity (e.g., broken wire, loose connection) preventing proper current flow.
• Motor parameters (e.g., P0-01, P0-02, P0-03) incorrectly entered or not matching the connected motor's nameplate.
• Mechanical load connected to the motor shaft during the identification run (Parameter C0003 enabled for identification).

Click steps to track your progress.

1. 1

   1. Verify secure connection and continuity of all three motor phases (U, V, W) at both the drive output terminals and the motor terminal box.

2. 2

   2. Measure the resistance between motor phases (U-V, V-W, W-U) with a multimeter; readings should be balanced.

3. 3

   3. Ensure motor nameplate data (Voltage, Current, RPM, kW/HP) is accurately entered into drive parameters (e.g., P0-01 to P0-05).

4. 4

   4. Confirm that the motor shaft is free of any mechanical load or restraint before initiating the identification run (C0003=1 or 2).
