Overcurrent in output stage

What does 01 mean?

An excessive current has been detected in the output stage of the MOVIMOT inverter. This typically indicates a short circuit, ground fault, or severe mechanical motor overload, causing the output current to exceed safe limits.

• Short circuit in the motor cable
• Ground fault in the motor winding or cable
• Severe mechanical overload on the motor

Click steps to track your progress.

1. 1

   Inspect connected machinery and motor for any mechanical obstructions, jams, or signs of excessive load.

2. 2

   Inspect the motor cable and terminal connections at both the MOVIMOT unit and the motor for physical damage, chafing, or loose terminations.

3. 3

   Measure the insulation resistance of the motor windings and motor cable to ground using an appropriate insulation tester (Megger).

4. 4

   Measure the phase-to-phase resistance of the motor windings (U-V, V-W, W-U) and compare readings for consistency.

5. 5

   Verify MOVIMOT inverter parameters, specifically motor nominal current, overload factor, and acceleration/deceleration ramps, are correctly configured against motor nameplate data and application requirements.
