Ground Fault

What does F13 mean?

This fault indicates that the drive has detected a leakage current path from one or more of its output terminals to earth ground. This typically points to a compromised insulation in the motor windings or the motor wiring, creating an unintended electrical path to ground. A ground fault is a serious safety concern, posing a risk of electric shock and potential damage to the motor or drive if not promptly addressed.
