I've not used that exact module, but having had a couple of surprises
like this, check your Startup List in TwinCAT. You might find TwinCAT
has set a non-default value for 0x8000:29/0x8000:2A which define the
steady state window. You might need to set these parameters to sensible
values with e.g. ecrt_slave_config_sdo().
There are a few Beckhoff slaves (e.g. AX5805, EP8309) where the list of
these startup parameters are so vast and intricate that it made sense to
write a TwinCAT XML startup list parser to do this automatically, rather
than have endless config knobs in our software.
