Article available in these languages: Spanish

Issue:
Would like to add an external 24Vdc supply to maintain communications when line voltage is missing, since this can be done with other Schneider Electric VFD's.

Product line:
ATV212, Altivar 212

Environment:
all models

Cause:
Line power loss

Resolution:
The ATV212 drive control section cannot be powered via external 24Vdc.  It requires line voltage to power the control section.
