What does 38 mean?

An unspecified internal error has occurred within the MOVIMOT® inverter. This type of error usually requires specialized diagnostic tools and expertise.

• Unspecified internal system malfunction.

Click steps to track your progress.

1. 1

   Verify input supply voltage (L1, L2, L3) at the MOVIMOT® inverter's main power terminals against the rated nominal voltage.

2. 2

   Inspect the motor cable for any visible damage, chafing, or signs of stress, and check all motor connections (U, V, W, PE) for tightness and proper termination.

3. 3

   Check all operational and motor-specific parameter settings within the MOVIMOT® inverter using SEW diagnostic software (e.g., MOVITOOLS® MotionStudio) for correctness and compare with the last known good configuration.

4. 4

   Measure the insulation resistance of the motor windings to ground and phase-to-phase with the MOVIMOT® inverter disconnected, ensuring it meets manufacturer specifications.

5. 5

   Perform a complete power cycle of the MOVIMOT® inverter by disconnecting and reconnecting the main power supply, then monitor for fault reoccurrence.
