General Function of Field-Oriented Closed-Loop Current

Control

In contrast to the functional principle used in the "torque/force control"

mode, this is actually is current control, as the actual current value is

measured and not the force or the motor torque. This means that open-

loop control of torque/force takes place, the torque or the force being

directly connected with the torque-/force-generating current via the

torque/force constant.

In the case of asynchronous motors, the torque constant is corrected

according to the active rotor flux.

With the firmware, it is possible to operate asynchronous and

synchronous motors in the entire speed range (including field weakening

range).

As a basic principle, we distinguish three working ranges that are

illustrated and described below:
