Earth Fault

Was bedeutet 3 ?

The drive's current measurement system has detected that the sum of the motor phase currents is not zero, indicating a leakage current to earth. This is typically caused by an insulation malfunction in the motor cables or within the motor windings itself, posing a risk of electrical shock or further equipment damage.

• Current leakage to chassis or ground detected.
• Insulation failure in motor windings or power circuitry.
• Faulty grounding connection.

1. 1

   Inspect the motor cables for any signs of damage, compromised insulation, or moisture ingress.

2. 2

   Perform an insulation resistance test (megger test) on the motor windings and cables to earth, and between phases, to identify insulation breakdowns.
