Y – Display Fault History
The last 8 errors from the fault history buffer are displayed. If a fault occurs while the drive is enabled, the fault
is saved into the fault history buffer. The last 8 errors are saved in NVM and recalled for display when this
command is issued. Only errors that occur while the drive is enabled are stored. This prevents nuisance errors
that commonly occur during startup/shutdown to be ignored.
YC – Clear Fault History
This command clears the fault history buffer in NVM. This command is useful after setting up a new system in
production to be sure any setup errors are cleared.
YS – Display SOA Fault History
This command displays the last saved SOA trip information from NVM. In the event of an SOA trip, all the
system parameters related to the trip are stored. This information is useful to the factory for troubleshooting SOA
events.
