Configuring the UDC Module’s Registers 3-29
Drive Status Register (Continued) 200/1200
Fault Detected Bit 8
The PMI Regulator sets the Fault Detected
status bit if any fault is detected. This bit is
reset by bit 8 of register 100/1100. Hex Value: 0100H
Sug. Var. Name: FLT@
Access: Read only
UDC Error Code: N/A
LED: N/A
See the description of the Drive Fault register (202/1202) for more information.
Warning Detected Bit 9
The Warning Detected status bit is set if any
warning is detected. This bit is reset by bit 9
of register 100/1100. Hex Value: 0200H
Sug. Var. Name: WRN@
Access: Read only
UDC Error Code: N/A
LED: N/A
See the description of the Drive Warning register (203/1203) for more information.
CCLK Synchronized Bit 14
The PMI Regulator sets the CCLK
Synchronized status bit when CCLK in the
UDC module is synchronized with CCLK in
the PMI Regulator. Hex Value: 4000H
Sug. Var. Name: CCLK_OK@
Access: Read only
UDC Error Code: N/A
LED: N/A
This bit is set to zero if CCLK is not turned on in the AutoMax rack or if there have
been two consecutive instances when CCLK is not synchronized after the
application task has 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 normally have to be
used in the run permissive logic for the drive (which must be true during the entire
execution of the task. Note, however, that applications requiring 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 to the Communication Lost Fault bit description (register 202/1202, bit 15) for
more information.
PMI Operating System Loaded Bit 15
The PMI Regulator sets the PMI Operating
System Loaded status bit when the
operating system has been successfully
downloaded from the UDC module to the
PMI Regulator after power-up. Hex Value: 8000H
Sug. Var. Name: PMI_OK@
Access: Read only
UDC Error Code: N/A
LED: N/A
