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:
