6. 24. 3 Detecting the stall time during power running to trip
<F452: Stall detection time during power running>
<F441: Power running torque limit level 1>
<F601: Stall prevention level 1>
■ Function
This function is one of the functions to prevent lifting gear from falling. If stall prevention operation
occurs in succession, this function judges that the motor has stalled to trip it.
■ Parameter setting
■ Setting method
1) In case of overcurrent stall
If, during power running, the output current reaches the value for <F601: Stall prevention level
1> or more, and continues for the period of time set for <F452: Stall detection time during
power running>, the trip "Ot2" will occur.
