Motor Overcurrent

What does 1 mean?

This fault signifies that the output current to either drive 1 (monitored by P300/P301) or drive 2 (monitored by P310/P311) has exceeded its configured cut-off limit for the parameterized delay time. This protective shutdown is often caused by excessive mechanical load on the motor, a short circuit in the motor windings or cables, or improperly set overcurrent parameters. Persistent overcurrent can lead to motor winding damage, thermal stress on cables, and potential failure of the MOVIFIT unit's output stage. If left unaddressed, this could result in costly motor replacement or unit downtime.

Complete Troubleshooting Guide

1. 1

   Check and adjust the overcurrent cut-off parameters (P300 for drive 1, P310 for drive 2) and their corresponding delay times (P301, P311) to ensure they are appropriate for the connected motors and application.

2. 2

   Reduce the mechanical load on the affected motor(s) to bring their operating current within safe limits.

3. 3

   Inspect the motor cables for the affected drive(s) and the motor windings for any signs of damage, short circuits, or insulation faults.

4. 4

   Verify that the mechanical system connected to the motor is not binding, experiencing excessive friction, or operating beyond its design capacity.
