7.5 Torque control

Goodrive310-UL 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 focuses 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.
