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 (9/290 only), connect the first to P4, connect the second to P6, and connect
the third to P5.

Analog drives attached to TB2 that incorporate an encoder to supply position feedback to the servo
module must be interfaced with one of the regular AXIS ”D shell”connections (J1, J2, or J3).
The ANALOG OUT (TB2) has no feedback capabilities.
J1, J2, and J3 D-Shell AXIS Connectors
The analog servo module sends drive signals to the servo amplifier through
connectors labeled J1, J2, and J3. Figure 4B.30 shows an end view of
connector J1, J2, and J3 and lists the pin assignments of these connectors.
