Afterwards, you have to call the control block cyclically in a cyclic interrupt OB (OB 30 to
OB 38). The cycle time of the cyclic interrupt OB has to be made known to the FB 41 using
the parameter CYCLE, in the above example 5 ms. When the controller is called, the
measured value of the current and the PWM setpoint of the 2PULSE are interconnected
directly with the controller. Other cyclic calls are not necessary.
