Manipulated value pulse controller

Pulse generator
The analog manipulated value (LmnN) can be emitted through pulse-duration modulation on
the output parameter QPULSE as an impulse sequence.
To use the pulse generator, proceed as follows:
1. Activate the "Activate" option check box in the "pulse generator" group.
2. Enter the "sampling time pulse generator", the "minimum impulse/break duration" and the
"period duration".
The following graphics clarify the connection between the "sampling pulse generator"
(CYCLE_P), the "minimum impulse/break duration" (P_B_TM) and the "period duration"
(PER_TM):
