Section 4C
Connecting the 4-axis Servo Module
4C-9
Axes are connected to the D-shell connectors marked J1, J2, J3 and J4.
Axes can be connected in any order on the servo module. However, if a
spindle with feedback is configured the spindle must be connected to the
first available D-Shell connector after the last connector used by a linear or
rotary axis.
ATTENTION: With analog systems, do not insert the
plug-type ANALOG OUT terminal block (TB2) into an encoder
termination panel DRIVE terminal block or vice versa.
Although these plugs will fit together, pin assignments are
different. Switching these connections without rewiring the
plug-type terminal block may cause damage to equipment.
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. 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.
