Wiring Power for your Feedback Device (Analog Systems Only)
The control supports feedback devices with 5v compatible output signals.
The voltage that these feedback devices require may vary. The processor
module is equipped to supply 5V dc power to feedback devices. These
voltages may be accessed directly from the encoder termination panel
If your feedback device requires an external power supply, it may be easily
incorporated through the EXT. POWER connector on the termination
panel. Power is then output through the ENC POWER connector terminal
labeled EX PWR OUT. The following figure shows the termination panel
connection for EXT. POWER. Refer to page 7A-1 for details on wiring to
ENC POWER.
