SECTION 4: MMI

Mechanical Assembly

The MMI assembly consists of the SR4 network controllers, the SMC (CY 5.4 controller & MS 2.0) motor drivers, all DC power supplies, and an AC power entry. The DC power supplies provide +5 vdc TTL computer (VCC) and +40 vdc motor (VMM). The VCC supply is over-current protected. In addition, A 1 amp AC fuse protects the entire assembly.

NOTE: NEVER REPLACE THE FUSE.

FUSE FAILURE INDICATES DRIVER FAILURE.

The green chassis lamp indicates VMM (motor) power on. The neon lamp in the power switch indicates that AC power is present to the MMI. The MMI has six pin motor connectors (see Appendix D), IEC power connector, network serial connectors (refer to serial cable section), and LED status indicators. The 20 pin CI cable connectors provides access to the spare I/O lines, limit loop, home sensor and VCC power/ground. Refer to Appendix A.
