7.3Torquecontroller
The torque controller is executed as a PI controller. The gain (P-component) and the
integral-action time (I-component) of the individual controllers are programmable. In
order to optimize the current control loop, two rectangular reference steps are preset.
The object of the optimization is a current controller with moderate dynamism and
the following values:
l Currentcontroltime:<1ms
l Overshoot:<5%

7.3.1Currentcontrolleroptimization
The faster the actual value approaches the setpoint, the more dynamically the
controller is set. The overshoot of the actual value should not be more than 5-10 %
of the setpoint (general figure) during the settling process.
