HF-Hardware fault trip codes
HF trips are internal hardware faults within the Drive. Powering the Drive down and re-
applying power could clear the fault.
For full list of hardware fault trip codes, refer to the Commander SE Advanced User
Guide.
If a HF trip occurs, the Drive Healthy relay will open to indicate this. The serial
communications will not function during a HF trip.
