Over-current

What does 11 mean?

This critical error indicates that the current drawn by the motor has exceeded a predefined maximum limit, protecting both the drive and motor from damage. It is often triggered by short circuits, sudden heavy loads, or excessively rapid acceleration.

• Short circuit in the motor windings or the motor cable.
• Sudden heavy mechanical load or a physical jam on the motor.
• Rapid acceleration ramp settings that demand excessive current from the drive.
• Faulty drive output stage or an issue with the current sensing circuit.

Click steps to track your progress.

1. 1

   Measure the insulation resistance of the motor windings to ground and phase-to-phase using a megger to check for short circuits.

2. 2

   Inspect the mechanical load for any obstructions, binding, or conditions that could cause excessive current draw.

3. 3

   Verify the acceleration ramp time in the drive parameters; increase it if it is set too aggressively for the load.

4. 4

   Check the motor cables for any signs of damage or short circuits between phases or to ground.
