In two-step control, only the positive pulse output QPOS_P of PULSEGEN is connected to
the on/off actuator. Depending on the manipulated value range used, the two-step controller
has a bipolar or a unipolar manipulated value range.
Two-step control with bipolar manipulated variable range (-100% to 100%)
Two-step control with unipolar manipulated variable range (0% to 100%)
The negated output signal is available at QNEG_P if the connection of the two-step controller
in the control loop requires a logically inverted binary signal for the actuating pulses.
