Use static control procedures when handling the jumper inside
the drive case.
The APS input is isolated from all other circuits on the Epsilon
drive including the DC bus, logic and I/O. This permits you to
use one common 24 VDC power supply for multiple drives
without concern for ground loops and noise coupling between
drives. The APS connection will generate some high frequency
ripple (.25 Amps at 80 khz) on the APS power lines. This may
disturb sensitive equipment that shares the same power
supply.
APS Input Specification
Using the APS supply input to power the drive logic and motor
encoder allows the drive bus to operate at DC voltages below 42
VAC (60 VDC bus). The drive will operate down to 12 VDC on
the bus (10 VAC on L1 and L2). However the low DC bus
monitoring must be disabled to prevent faults at these low DC
bus voltage levels. This can be done with PowerTools software
on the Advanced tab in Detailed Setup mode.
Caution
Do not wire AC line into the APS input. Doing so will
damage the drive.
