Controller cycle time
The internal controller cycle time depends on the configured automation system and on the
PWM period. The controller cannot control the current faster than the parametrized PWM
period, as the measured current is averaged over an entire PWM period.
If Dithering is active simultaneously with current control, the PID controller uses the Dither
period duration as the internal controller cycle time.
Resetting the PID current controller
The internal data of the current controller are reset in the following cases:
● SW_ENABLE (see control interface) is low.
● A new parametrization record is sent to the module.
