Regenerative torque limit level 2

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.
Set the torque limit values for the power running and regenerative torques at <F441: Power running torque limit level 1> and <F443: Regenerative torque limit level 1>.
Set limit treatment of the constant output zone (weak magnetic field) at <F454: Torque limit in field weakening>. You can select either constant output limit <F454> = "0" (default setting) or constant torque limit <F454> ="1".

2) When torque limits are applied by external signals
Torque limit value can be changed by external signals.
• When setting with input of 0 to 10 Vdc to terminal [RR]
Set "1" for <F440: Power running torque limit input select 1> and <F442: Regenerative torque limit input select 1>.
• When setting with input of -10 to 10 Vdc to terminal [RX]
Set "2" for <F440: Power running torque limit input select 1> and <F442: Regenerative torque limit input select 1>.
• When setting with input of 4 to 20 mAdc to terminal [II]
Set "3" for <F440: Power running torque limit input select 1> and <F442: Regenerative torque limit input select 1>.
