Connecting the 4-axis Servo Module
4C-10
Servo Module Interface Connector - P1
The servo module is interfaced with the motherboard through connector
P1. The control transmits and receives various signals to and from the
servo module through this connector.
Servo Connectors - J1, J2, J3, and J4
The servo module sends drive signals to the servo amplifier through the
connectors labeled J1, J2, J3, and J4. Figure 4C.7, Figure 4C.8, and
Figure 4C.9 show an end views of one of these connectors and lists the pin
assignments for the different versions of 4-axis modules.
