Rockwell Automation SA3100 Power Module Interface (PMI) Regulator - Manual (Page 19)

PMI Regulator Motherboard 2-3
2.1.5 Synchronous Transfer Port Connector
The Synchronous Transfer Port connector is reserved for future use of the
synchronous transfer function. However, connections may be made to three of its pins
in order to measure real-time current feedback. See section 2.2.4.

PMI Regulator status is indicated by an
LED board mounted above the
motherboard. Five of the LEDs indicate
the status of the PMI processor and the
connected drive. The other nine LEDs
indicate the status of the Resolver & Drive
I/O board.
The LEDs are defined in the following
descriptions. See the SA3100 Drive
Configuration and Programming
instruction manual (S-3056) for a complete
description of the registers and status bits
referred to in these descriptions.
