time
Setting range: 0~3600.0s
When the drive sleeps and decelerates to
the lower limit frequency, it will run at
the lower limit frequency for the time
defined by F8.35 and then go to zero
frequency operation.

1: Stop after a single cycle: The drive will
stop automatically after completing one
cycle. You need to give a run command
again to start.
2: Keep the final value after a single
cycle: The drive will automatically keep
