Overcurrent in power section

What does E8028 mean?

The current flowing through the drive's power section has exceeded its maximum safe limit. This is a critical warning that indicates an immediate risk of damage to the drive or motor.

• Short circuit in the motor windings or motor power cables.
• Motor or mechanical system experiencing a severe overload or mechanical blockage.
• Incorrect drive parameters (e.g., motor current limits, control gains) leading to instability.
• Faulty current measurement circuitry within the drive.

Click steps to track your progress.

1. 1

   Check motor windings and power cables for short circuits or ground faults using appropriate continuity and insulation tests.

2. 2

   Inspect the mechanical system for any binding, blockage, or excessive friction that could cause high motor current.

3. 3

   Verify all drive parameters related to motor control, current limits, and load conditions against the motor nameplate and application requirements.

4. 4

   Monitor the actual motor current during operation to identify when the overcurrent condition occurs.
