[etherlab-users] EL2502 problem

[Michael Sagner]

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

Hello Michael,

the documentation makes a note about different Hardware Versions.

Changing the period via pdo mapping is only supported for version higher or
equal than 01.

Please show following outputs
-ethercat slaves -px -v
-ethercat pdos -px
