• Function
This function is to decrease or increase the output frequency according to the loading condition when the
motor torque reaches the limit level. Setting a torque limit parameter at 250% means “Invalid.”
■ Setting methods
(1) When setting limits to torque, use internal parameters (Torque limits can also be set with an external control
device.)

Torque limits can be set with the parameters H and H.
[Setting of power running torque]
H (Power running torque limit 1 selection) : Set at (H)
H (Power running torque limit 1) : Set a desirable torque limit level.
[Setting of regenerative torque]
H (Regenerative braking torque limit 1 selection) : Set at (H)
H (Regenerative braking torque limit 1) : Set a desirable torque limit level.
