7000A-RM001A-EN-P – January 2011 7000 “A” Frame
Non Isolated Process Outputs
The drive supplies four non isolated -10/0/+10 V outputs for customer use.
These outputs can drive loads with impedances as low as 600 ohms. 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 watts at +24 volts. 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.
