Stall prevention function

6.26.1 Power running stall continuous trip detection time

 : Power running stall continuous trip detection time
• Function
A function for preventing lifting gear from failing accidentally. If the stall prevention function is activated in
succession, the inverter judges that the motor has stalled and trips.

6.26.2 Regenerative braking stall prevention mode selection

 : Regenerative braking stall prevention mode selection
• Function
A function for preventing lifting gear from stopping in the wrong position. Only the function of preventing a
stall by maintaining the current constant during regenerative braking (deceleration stop) is deactivated.

6.26.3 Stall prevention control switching

 : Stall prevention control switching
• Function
The operation of the stall prevention control can be switched. Set
are displayed when acceleration and the deceleration are switched.
This parameter is effective at only V/f control mode(=,,).
