Message Operation
The specified fault Clear/Reset 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 EEPROM to RAM.
