74.51 On time 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 counter.
0.0
0.0...90000.0 min On time. 1 = 1min
74.52 Off 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 counter.
0.00
0.0...90000.0 min Off time. 1 = 1min
74.79 Fly-start speed
check
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 is ON. Since 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 parameter 74.39 Measurement
delay.
