4.7.8.3 Testing Feedback Registers and Bits
This section describes how to test the feedback registers and bits listed in table 4.4.
Fault, warning, and interlock registers are described in Appendices A, B, and C. Use
the AutoMax Programming Executive I/O Monitor function to display the registers and
bits in the format listed in table 4.4.
Step 1. Verify that register 200/1200, bit 15 is on. This bit is on when PMI operating
system has been successfully downloaded from the UDC module to the PMI
Regulator.
Step 2. Check each of the inputs identified by bits 1 through 5 of register 201/1201
by applying 115V to the appropriate pins on the Drive I/O connector on the
Resolver and Drive I/O board and verifying that the appropriate bit is on.
Refer to instruction manual S-3057, PMI Regulator, for the pinout
description.
