Auxiliary Power Supply You may use an auxiliary power supply to keep the 700S control assembly
energized, when input power is de-energized. This allows the main control board,
DriveLogix controller and any feedback option cards to continue operation.
Connect auxiliary power to J15 on the fiber optic interface board. You must set
parameter 153 [Control Options], bit 17 “Aux Pwr Sply” to enable this feature.

IMPORTANT For drives manufactured prior to June 2006, the voltage feedback board
provides the bulk 24 volts for the fiber optic interface board. If the auxiliary
power supply (24 volts) is greater than the voltage feedback board (24 volts)
then the switch mode power supply on the voltage feedback board will shut
down. If the auxiliary power supply has an adjustable voltage, then the voltage
should be lowered (23.75). This will allow the voltage feedback board power
supply to supply the 24 volts. If the auxiliary power supply cannot be adjusted,
then a 500 W resistor needs to be added to the voltage feedback board. In this
case, please contact Drives Technical Support for details.
