Message Operation
The Fault Clear/Reset function specified in the PMW sends a fault
handling request to the drive.
•
A Clear Fault Request clears the last fault that occurred and
makes the drive available to run.
•
A Clear Fault Queue clears the entire fault buffer.
•
A Drive Reset resets the drive and clears any parameters or links
not saved. Parameter information stored in EEPROM is written to
RAM.
If an error has occurred in the block transfer, word 2 of the PMR
returns a value of -30976.
