MMI

The MMI Multi-Axes Motion Controllers provide control of up to eight step motors. Each motor controller is independent. Each supports a home sensor, limit safety loop, and six bits of general purpose I/O (input/output). In addition, up to eight MMI motion controllers can be "daisy-chained" together with simple pin-to-pin DB9 serial cables for a total of 64 motors per serial port.

The MMI system consists of three major sub-assemblies: two SR4s (Serial Repeater 4-channel) network communication controller cards; up to eight SMCs (Step Motion Controller) cards; and the power supplies. The MMI system is packaged in a 19" format enclosure suitable for 19" rack mount or free standing (bench-top) applications.

During operation, the SR4 net controllers send and receive commands from the host CPU using the RS-232 communication port. There are 2 command sets; one for the Cybernetics CY233 net controllers and the other for the Cybernetics CY545 (550) SMC motor controllers. The CY233 uses only 4 commands. The CY545 has 26 commands; refer to the CY545 Motion Controller manual for details. The CY number refers to the model of microprocessor used in this system.
