■ Function
When the motor-generated torque reaches a certain level, the inverter reduce the torque by lowering
the output frequency.
You can select a constant output limit or a constant torque limit in the constant output zone.
■ Selecting a setting value
1) When torque limits are applied by the parameter setting values
Select from where to input a torque limit value at <F440: Power running torque limit input select
1> and <F442: Regenerative torque limit input select 1>.
As default setting, torque limits are applied by the parameter setting values.
