Sets whether to execute Auto restart and the number of attempts to perform within a set time. Drive output is shut
off and operation stops if the number of Auto Restart attempts exceeds the set value during the set time. In such
cases, resolve the cause of the fault and manually restart the drive.
DANGER! Sudden Movement Hazard. Never use the fault restart function so that the drive restarts the application after a fault
occurs in hoist or lifting applications. Failure to comply may result in death or serious injury.
The drive can execute the Auto Restart function when the following faults occur.
