Connecting the Main Power Supply to the Servo Module for
+5V dc Encoders on 9/260 and 9/290 Systems
The servo modules gets power directly from the motherboard. However,
5V dc encoder power, which runs through the servo module, must come
directly from the main power supply.
Important: Some applications may not require the use of the servo
module’s 5V dc encoder power (i.e., servo modules 15V dc encoder power
or an external power supply is used). For these applications, this
connection is not necessary.
The main power supply provides 3 wires (with connectors) for 5V dc
encoder power supply. These wires are shown in Figure 4D.2.
Connect any of the 5V dc encoder power wires to connector on your servo
module that is shown here:
