Current controller

Properties
S PI controller for current control
S Four identical current setpoint filters
S Current and torque limitation
S Current controller adaptation
S Flux control
Closed-loop current control
No settings are required for operating the current controller. The controller can be
optimized for special applications (see Section 3.1.12).
Current and torque limitation
The current and torque limitations are initialized when the system is commissioned
for the first time and should be adjusted according to the application.
