To verify that communication between the UDC module and the PMI is resulting in up-to-date
feedback data, it is recommended that the drive’s run permissive logic include the CCLK
synchronized status bit (register
200/1200,
bit 14,
CCLK_OK@)
and the communication lost fault bit
(register
202/1202,
bit 15,
COM_FLT@)
as shown below:
