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".
