Message Operation
The specified fault command function sends a fault handling request
to the device.
A Clear Fault request clears the last fault that occurred.
A Clear Fault Queue clears the entire fault buffer. Certain devices
may store more than one fault.
A Drive Reset is used with the 1336 FORCE drive product only.
This function resets the drive; it clears the fault queue and writes
the parameter information stored in NVS Storage to RAM.
