6.7 Pulse width modulation - PWM
6.7.1 Overview
With the pulse width modulation (PWM) by presetting of time parame-
ters the CPU evaluates a pulse sequence with according pulse/break
ratio and issues it via the according output channel.
1 Period duration
2 ON delay
3 Pulse duration
4 Pulse pause
During pulse width modulation the count function at the
same channel is deactivated.
For pulse width modulation connect your actuators to the following
pins:
Channel 0: Pin 22
Channel 1: Pin 23
Connect the common ground to pin 30.
