Defines the time for the motor to stay ON.
After the ON cycle is over, drive will automatically shut
down and switch to 74.52 Off time
On time.
Defines the time for the motor to stay OFF.
After the OFF cycle is over, drive will automatically shut
down and switch to 74.51 On time
Off time.
Defines the source for the Fly start check enable signal.
The function will check the actual motor speed before
making decision on starting procedure.
If the speed is outside safe-to-restart speed region,
then the control program logic will skip starting
routines and get in to production state from the current
motor speed.
Note: This parameter setting has no effect in case
parameter 74.30 Speed observer enable
the Fly-start speed check employs backspin observer
function to check the speed. Also, by activating this
parameter will delay normal start of the drive for the
time necessary to perform measurement defined in
