ID1 (Error during motor data identification)

What does 0140 mean?

An error occurred during the motor data identification process. This can be caused by a disconnected motor, excessively high stator resistance, or the controller being externally inhibited during the identification sequence.

• Motor not connected to the drive output terminals (U, V, W) or poor connection.
• Motor cable broken, shorted, or high resistance due to aging or damage.
• Motor's stator resistance is excessively high, indicating internal winding damage or a motor mismatch.
• External enable signal (e.g., P2-01 parameter) is de-activated during the identification process.
• Motor is mechanically inhibited (e.g., brake engaged, shaft seized) preventing rotation during identification.

Click steps to track your progress.

1. 1

   Verify the motor is securely connected to the drive's U, V, W output terminals, checking for loose wires or corrosion.

2. 2

   Measure the resistance between each motor phase (U-V, V-W, W-U) at the drive terminals; values should be balanced and within motor datasheet specifications.

3. 3

   Check the insulation resistance of the motor windings to ground and between phases using a megohmmeter (e.g., 500VDC).

4. 4

   Ensure the drive's enable input (e.g., terminal X3/1 if configured for run) is active (HIGH) and not inhibited during the ID run.

5. 5

   Confirm the motor shaft is free to rotate and not mechanically locked by a brake or seized bearing.
