Auxiliary Logic/Alternate Power Wiring Supply
Auxiliary Power Supply (APS) allows the drive to retain motor position information and
serial communications when the main AC power supply is disconnected. You must reset the
drive, either using the reset button or a reset input, after AC power is re-applied if the backup
supplies have been active.
Epsilon Only
If the low DC bus fault is disabled with PowerTools software on the Advanced tab,
resetting the drive is not necessary.

Auxiliary Logic Power Usage (E
The auxiliary logic power connector is accessed through a plastic punch-out tab located on
top of the drive that reads "BUS/AUX". The auxiliary logic power for each EN drive must be
individually transformer isolated from the AC supply. The voltage range is 127 to 373 VDC,
at 21 watts. This can be accomplished by isolating, rectifying and filtering 90 to 264 VAC.
EMERSON Motion Control offers Auxiliary Logic Power Supplies (models ALP-130 and -
430) that supply enough power for one E Series drive with an FM-P module and four E Series
drives with FM-P's respectively. See the "Options and Accessories" section for more
information.
Warning
Do not connect AC power directly into the auxiliary logic connector. You must wire this
connection correctly with transformer isolated 127 to 373 VDC power. Failure to do so
can cause death, serious injury or equipment damage. Also, use caution when removing
the plastic punch-out tab. AC power must be disconnected for at least 30 seconds before
removing the tab.
