What does 7 mean?

This fault indicates an internal issue such as a defective component or a short-circuit/overload in the brake resistor circuit. If accompanied by Fault 1 (Overcurrent), it suggests a problem with the motor cable or the motor itself, leading to saturation conditions within the drive's output stage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    If Fault 7 occurs concurrently with Fault 1, inspect the motor for insulation issues or internal damage.
