PWM Frq
In this operating mode, the frequency can vary from 0… 20 kHz via the process
image. The duty cycle can be preset in the Parameterization dialog. The default
value is “50 %”.
All four available channels can be used independently of each other. To double
the output current, it is possible to connect a channel pair (DO 1 and DO 2 or DO
3 and DO 4) in parallel. “Bridge mode” must be enabled in the settings. The
operating mode and the values of the first channel (DO 1 or DO 3) are also
applied to the respective parallel channel (DO 2 or DO 4). The output data of the
parallel channel in the process image is irrelevant in bridge mode.
The corresponding channel pair is now synchronized. The load must be wired
accordingly at both outputs of the channel pair.
