Axis Modules Overview

An axis module is the part of the RMC75 motion controller that interfaces to the transducers and drives. The axis module is mounted on the front of the RMC75 Control Module (see the RMC75 Modules Overview topic for an image). It has status LEDs and connectors for the axis wiring.

An axis module can have one or two axes. Each axis has one transducer interface, one ±10 Control Output, one Fault Input, and one Enable Output.

For other module types without a Control Output, such as analog input, digital I/O, and quadrature input, see the Expansion Modules. For a description of the various module types that make up the RMC75, see the RMC75 Modules Overview topic.

Available Axis Modules

The following axis modules are available for the RMC75:

(the number indicates the number of axes)

Module	Transducer Input Type	Control Output
MA1	MDT or SSI	±10V
MA2	MDT or SSI	±10V
AA1	Analog (±10V or 4-20 mA)	±10V
AA2	Analog (±10V or 4-20 mA)	±10V
QA1	Quadrature (5V RS-422)	±10V
QA2	Quadrature (5V RS-422)	±10V
