Frequently asked questions

Please note that, the drives do not require external 24VDC as the electronics get supplied internally when the input line voltage is on.
However, if you use an external 24VDC, then this can supply the control board with power when input line voltage is off. 

P24 terminal is the +24Vdc external input supply.
Power the drive control using P24 and 0V terminal to keep the control ON when the main supply is off.
