The assignment of a function-no. to a certain channel happens during
parameterization. The function-no. 00h does not influence the function-no.
stored in the permanent parameterization data.
By entering FFh you may deactivate the concerning channel.
The following tables list all functions that are supported by the depending
channel.
You may find the connection type mentioned under "connection" at the
"circuit diagram" above.
Note!
When exceeding the overdrive region, the value 7FFFh (32767) is thrown,
at underrun of the underdrive region the value is 8000h (-32768).
