Appendix A: Wiring

This section describes how to wire the following RMC modules to feedback

transducers and drives:

• Analog

• MDT

• SSI

• Quadrature

• Quadrature (with stepper output)

General Wiring Information.

For CE compliance and to minimize electrical interference:

• Use twisted pairs for all wiring where possible.

• Use shielded cables for all wiring.

• Keep RMC wiring separate from AC mains or conductors carrying high

currents. Especially high frequency switching power such as conductors

between servo drives and motors or amplifiers and proportional valves.

For UL and C-UL compliance:

• Power supply must be Class 2.

• All RMC inputs and outputs must be connected to Class 2 circuits only.

RMC Drive Outputs

Four-Pin Plug-in Terminal Block

Pin Function

1 Axis 0 Drive

2 Drive Common

3 Axis 1 Drive

4 Case

When positive voltage is sent to an axis’s drive, the axis must extend. The extend

direction is defined as the direction that causes the transducer to return increasing

counts. The extend direction of a magnetostrictive transducer is away from the

head.

CAUTION: If the outputs from the RMC are reversed, the axis will be

uncontrollable when power is connected. Confirm that your wiring is correct!
