Connecting the 3-axis Servo Module
4B-7
The functions of the digital servo module are designed to make the axes
run with optimum performance. Generally, the maximum feedrates are
limited by the mechanical abilities of the machine. System gain and the
maximum allowable following error will also limit the feedrates. These
limits are entered as AMP parameters. Refer to the 9/Series CNC 9/230,
9/260, and 9/290 AMP Reference Manual, publication 8520-6.4, for more
information.
Table 4C.A lists the connectors that are used to integrate the digital servo
module with other modules of the control.

Important:
When 1 servo module is used, it must be connected to P4 of the motherboard. When 2
servo modules are used, the first servo module must be connected to P4 and the second to connector P6.
9/290 only, when three modules are used, connect the first to P4, the second to P6 and the third to P5.

If a spindle incorporates an encoder to supply position feedback to the servo module, the spindle
encoder must be interfaced with the last open connector of these 3 connectors. Refer to the
9/260-9/290 AMP Reference Manual, publication 8520-6.4, for more information.
CN1 Servo Module Interface Connector
The servo module is interfaced with the motherboard through connector
CN1. The control transmits and receives various signals to and from the
servo module through this connector.
