Current controller
No settings are required for operating the current controller. Tuning measures can be taken
in certain circumstances.
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.
Current controller adaptation
The P gain of the current controller can be reduced (depending on the current) by means of
current controller adaptation. Current controller adaptation can be deactivated with the
setting p1402.2 = 0.
