Can an external 24Vdc power supply be used on the ATV212 or ATV312 to power the control board for programming?

Published date: 24 June 2020

Issue: 
Attempting to program the VFD without applying main power to L1L2L3.

Product Line
ATV212 ATV312

Environment:
All models

Cause:
Need to power-up the display to program the drive

Resolution:
Neither the ATV212 nor ATV312 has the capability to power the control board from an external 24Vdc power supply.  To program the VFD on the integral keypad, power needs to be applied to the line terminals.  Single phase or three phase power can be used; however, use the appropriate voltage, 230Vac or 480Vac, based on the drive's voltage rating.
