Earth leakage

What does 2330 mean?

An earth (ground) fault or significant current unbalance has been detected in the motor circuit, specifically within the motor itself or its connecting cables. This is a critical safety hazard and can cause severe damage to equipment or pose a risk of electric shock.

Complete Troubleshooting Guide

1. 1

   De-energize the system and perform an insulation resistance test (megger) on the motor and motor cables to ground.

2. 2

   Inspect the motor cable for any signs of insulation damage, chafing, or moisture ingress.

3. 3

   Verify proper grounding of the motor frame and the drive's protective earth connection.

4. 4

   Disconnect the motor from the drive and test the drive's output for earth fault detection if the motor and cables are clear.
