Issue:

Motor circuit is open. Running the VFD at 10Hz output does not result in an expected OPF2 fault.

Product Line:

ATV630

Environment:

All models

Cause:

Controls qualification testing requires a fault scenario.

Resolution:

The ATV630 Motor control type is factory set to UFVC Quad. Due to the control algorithm, the output phase loss fault may not be triggered at low speeds on smaller HP drives.

To test the fault status controls, temporarily set Motor control type = UFVC 5pts.
