n
Ratio Factor > 1
The pulse duration at the positive pulse output calculated from the input variable mul-
tiplied by the period time is reduced by the ratio factor.
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 being used, the two-
step controller has a bipolar or a monopolar manipulated value range.
n
Two-Step Control with Bipolar Manipulated Variable Range (-100 % to 100 %)
n
Two-Step Control with Monopolar Manipulated Variable Range (0 % to 100 %)
The negated output signal is available at
QNEG_P
if the connection of the two-step con-
troller in the control loop requires a logically inverted binary signal for the actuating
pulses.

In the manual mode (

= TRUE), the binary outputs of the three-step or two-step
controller can be set using the signals
POS_P_ON
and
NEG_P_ON
