Chapter 1 Detailed Drive Operation
Parameter 895 [SL CRC Error] displays the number of CRC errors that occurred
during the last test (last 8 ms). This data is visible on the SynchLink diagnostics
tab of the Peer Communication window.
Parameter 896 [SL BOF Err Accum] displays the total accumulated number of
BOF (Beginning of Frame) errors. Clearing a fault resets this accumulator. This
data is visible on the SynchLink diagnostics tab of the Peer Communication
window.
Parameter 897 [SL BOF Error] displays the number of BOF errors that occurred
during the last test (last 8 ms). This data is visible on the SynchLink diagnostics
tab of the Peer Communication window.
Parameter 898 [SL CRC Err Limit] identifies the number of CRC 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.
Parameter 899 [SL BOF Err Limit] identifies the number of BOF errors per test
(per 8 ms) allowed before the drive declares a SynchLink BOF Error exception
event. Set this limit on the SynchLink diagnostics tab of the Peer
Communication window.
Parameter 900 [SynchLink Rev] indicates the current revision of the local
SynchLink Programmable Logic firmware.
Parameter 901 [SL System Rev] indicates the system revision of the SynchLink
network. To be compatible on the network, all nodes must have the same major
revision.
Parameter 902 [SL Error Status] and parameter 903 [SL Error History] indicates
the presence of SynchLink™ faults. This data is visible on the SynchLink
diagnostics tab of the Peer Communication window.
• Bit 0 “Sync Loss” indicates SynchLink communication has failed, after it
had been established
• Bit 1 “Rx Loss” indicates the receive port is not receiving data, and the
receive port configuration is set to receive data
• Bit 2 “Many BOF Err” indicates the number of Beginning Of Frame
(BOF) errors exceeds limit set by Par 899 [SL BOF Err Limit]
• Bit 3 “Many CRC Err” indicates the number of Cyclic Redundancy Check
(CRC) errors exceeds limit set by Par 898 [SL CRC Err Limit]
• Bit 4 “Pckg Msg Err” indicates the received package sequence number has
not matched for 1.0 second
