SL BOF Error
Displays the number of BOF (Beginning Of Frame) errors that
occurred during the last test (last 8 mS). This data is visable
on the SynchLink diagnostics tab of the Peer Communication
window.

SL CRC Err Limit
The number of CRC (Cycling Ring Checksum) errors per test
(per 8 mS) allowed before the drive declares a SynchLink CRC
Error exception event. Set this limit on the SynchLink
diagnostics tab of the Peer Communication window.

DM Com Prt Stat
Indicates faults or warnings related to the Drive Module’s
Drive Communication ports.
• Bit 0 [Bad Rcv Int] indicates the interrupt generated by
the Universal Serial Controller (USC) is not properly
marked
• Bit 1 [No EOF] indicates the USC did not report an End
of Frame condition when the recieve interrupt was
generated
• Bit 2 [CRC Error] indicates the USC has reported a
Cyclic Redundancy Check (CRC) error on the last frame
(message) received
• Bit 3 [Overrun Err] indicates the USC has reported a
receive firs-in, first out error
• Bit 4 [DMA Error] indicates the length of a received
message did not match the length encoded in the
message itself
• Bit 5 [Xmit Underun] indicates the USC has reported a
transmit first-in, first-out underrun
• Bit 6 [Sync Error] indicates two or more CCLK counter
ticks occurred and no message was recieved
• Bit 7 [LoopBack Err] indicates failure in the loopback
test (the transmit message did not match the receive
message). The Drive Module performs this test on
power-up and reset.
• Bit 8 [Missed Gains] indicates gain data could not be
written because memory was being written to when
the gain values were received
• Bit 9 [Multplx Err] indicates data which is multiplexed
into a command/feedback message has not verified
correctly

DPS/PMI
• Bit 10 [No PMI OS] indicates the correct PMI operating
system is not present in the Drive Module and the PMI
is requesting an operating system
• Bit 11 [Bad OS Hdr] indicates the Drive Module cannot
locate a valid PMI operating system header when
attempting to load an operating system to a PMI
• Bit 12 [Bad PMI HW] indicates PMI hardware is not
compatible with the PMI operating systems in the
Drive Module
