What can cause an (FrF) line frequency fault on the ATS48 Soft Starters?

Populaire vragen (FAQ's) zoeken

Change Parameter FrC from AUt to 60. This changes the tolerance to plus/minus 20%.

Remove and inspect the green terminal strips at the bottom of the softstart. Securely reinstall the strips.

Confirm that control power is present on CL1-CL2 terminals before a Run command is given. Delay the Run command until nLP or rdY codes appear on the display.

Is the power supply from a generator?. If so, check the frequency of the line to see if it is out of tolerance. Upgrade the generator if necessary. The FrC setting accommodates Class 1, 2 or 3 generators as defined by the Electrical Generating Systems Association.

Contact the Drives Product Support Group if the fault continues after corrective action.
