CN25M +5V dc Power Supply Connector
Use connector CN25M on the optional feedback module to connect a +5V
dc power supply to the optional feedback module. Typically the optional
feedback module receives +5V dc power from the main power supply
through connector CN25M. This +5V dc power supply powers the
encoders of the digital servo module and the non-motor mounted feedback
devices of the optional feedback module.
When the sum of the power requirements of the servo module and the
optional feedback module exceed the +5V dc output of the main power
supply, use an external power source to supply the +5V dc power.
Figure 4B.19 shows an end view of connector CN25M and lists the pin
assignments.

2 GND Ground System Common
Use jumper JP1 on the optional feedback module to select whether the
+15V dc power supply for the non-motor mounted feedback devices is :
supplied from the main power supply
supplied from an external power source
removed from the feedback connectors
Non-motor mounted feedback devices receive +15V dc power through pins
3 and 4 of connectors CN14F, CN15F, and CN16F on the optional
feedback module. Figure 4B.20 shows the jumper selections of jumper
JP1.
