Meaning
output of a single pulse with defined On delay and variable pulse dura-
tion (e.g. for dosing using a switch valve)
Closed-loop current control, e.g. for controlling the temperature in a
•
heating resistor
Output of a frequency with defined period duration and variable duty
•
cycle (e.g. for controlling a proportional valve)
Optional dithering: superimposition of a dither signal on the PWM
•
signal for improving proportional valve control
output of a train of pulses with defined period duration and variable pulse
count
pulse output follows the signal at digital input DI0 after a defined switch-
ing delay (e.g. for delayed output with higher output current)
output of pulses with variable frequency and fixed mark-to-space ratio of
1:1
Output of a bipolar PWM signal with variable duty cycle for controlling a
brushed DC motor in both directions of rotation
