4.1.4 Wiring Methods for P1 Power Supply Connector
Power for the M2DC servo drives comes from 2 different sources

Input Power
Main power supply
V+, V-
Drive’s main power input
20 - 70VDC
Control circuitry power/
auxiliary power
AUX, V-
When the main power supply is off,
the AUX power will keep the logic
circuitry alive, allowing the drive
to remember its current state data
(motor position, etc.) The motor is
then able to resume operation without
running a homing routine while the
main power is switch-on again.
