Description:
The A-C Line Phase ABC bit is equal to one when the A-C line is phased ABC (181,
182, 183). If needed, the application program may test this bit to determine the A-C line phasing. This
bit is equal to zero when the A-C line is phased ACB. Bit 11 is set equal to one when the phasing has
been detected. The system automatically adapts to either ABC or ACB phasing without user pro-
gramming. This bit is checked by the armature and field algorithms, alpha tests, and identification
tests.

Description:
The Phase Synchronization Ready bit is set equal to one when the A-C line phasing
has been detected. If the A-C line phasing has not been detected, check the incoming A-C power
lines. When this bit is set, the status of bit 10 is valid.

UDC Error Code:

LED:
N/A
Description:
The PMI Processor sets the CCLK Synchronized bit when CCLK in the UDC module is
synchronized with CCLK in the PMI Processor. This bit will be equal to zero when CCLK is not turned
on in the AutoMax rack or if there have been two consecutive instances when CCLK is not synchro-
nized after you have turned CCLK on. In this case, the feedback data from the PMI is not current.
This bit should normally be used only in the start permissive logic for the drive (which must be true
only once to start the drive). It does not have to be used in the run permissive logic for the drive
(which must be true during the entire execution of the task).
Note that applications that require very tight synchronization between the UDC module and the PMI
(e.g., positioning applications) may require the use of this bit in the run permissive logic.
Refer also to the Communication Lost fault bit description (register 202/1 202, bit 15).

Description:
The PMI Processor sets the PMI Operating System Loaded bit when the operating sys-
tem has been successfully downloaded from the UDC module to the PMI Processor after power up.
