Ground Fault

What does F013 mean?

This fault signifies an unintended current path from the motor or drive output system to ground. It typically occurs during motor acceleration or deceleration and can pose a significant safety risk, lead to equipment damage, or cause electrical interference if not promptly addressed. This indicates a breakdown in insulation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect motor windings, motor cables, and drive output connections for any signs of insulation breakdown, chafing, or short circuits to ground.

2. 4

   Measure insulation resistance between motor phases and earth using a megger; expect values greater than 1 MΩ.
