Non-Isolated Process Outputs
The drive supplies four non isolated -10/0/+10V outputs for customer use. These
outputs can drive loads with impedances as low as 600 . These outputs are all
referenced to the Drive AGND and therefore should be isolated if they are required
to drive outside the PowerFlex ‘A’ frame enclosure.

Auxiliary +24V Power Supply
An Isolated 24V Power Supply is built into the DC/DC converter (Connector
P3). This supply may be used for any customer supplied equipment requiring up
to 24 W at 24V. This supply may also be used to power any custom drive options,
such as isolation modules for additional Process Control Outputs. The health of
this power supply is monitored in the drive.
The ACB is common for both the line and motor side current feedbacks.
Different scaling resistors are mounted on the terminal block for line side and
machine side
There are two LEDs on the ACB labeled D7 and D9. D9 is the ±15V DC
voltage-OK signal, and D7 is the +5V DC voltage-OK signal.
