Why would the ATV21 and ATV212 drives be showing OFF on the display?

Issue:
Why would the ATV21 and ATV212 drives be showing OFF on the display?

Product Line:
Altivar ATV21 and ATV212

Environment:
All

Cause:
Run permissive is programmed and the logic input is open (off).

Resolution:
Check F110 in the F------ codes.
If F110 is 0 then F111, F112 or F113 will be 1 or 56 which is your run permissive input.
Change F110 back to 1 to turn if off or turn on the input that is assigned as your run permissive.
If you have an SFlex enclosed drive put the AFC off Bypass switch in AFC mode.
