Issue:

Disabling OPF on an ATV630/930 drive.

Product Line:

ATV630/930 drives

Environment:

All

Cause:

Customer wanted to know how to test drive in open circuit.

Resolution:

Keep in mind that this will disable the output phase loss protection. It may be advisable to provide external phase loss protection for the motor by using overloads.

Go to Complete Settings, and press enter, then scroll down to Error/Warning Handling and press enter, then scroll down to Output Phase Loss and press enter and set to Function Inactive.

** Note: While this will allow you to run with an output disconnect or contactor that may cause nuisance tripping, there are other parameters which also have to be changed in order to run

the drive with no motor or no load on the motor.
