Need to power-up the display to program the drive

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.
