Torque Control - INVT Goodrive200A Series Operation Manual

GD200A series VFD

7.4 Torque control

Goodrive200A series VFDs support two kinds of control mode: torque control and rotation speed
control. The core of rotation speed is that the whole control focuses on the stable speed and
ensures the setting speed is the same as the actual running speed. The max. load should be in the
range of the torque limit. The core of torque control is that the whole control focus on the stable
torque and ensures the setting torque is the same as the actual output torque. At the same time, the
output frequency is among the upper limit or the lower limit.
