Hello -<br />
This problem is still unsolved.<br />
What do I have to do to adjust the PWM frequency?<br />
Any hints appreciated.<br />

<br />
Hello Michael,<br />
<br />
the documentation makes a note about different Hardware Versions.<br />
<br />
Changing the period via pdo mapping is only supported for version higher or<br />
equal than 01.<br />
<br />
Please show following outputs<br />
-ethercat slaves -px -v<br />
-ethercat pdos -px<br />
<br />
<br />
