ethercat-conf.xml pdoentry limits?

i have the attached ethercat-conf.xml (for stepperonline A6 servos).
Each time i add more than 10 pdoentry tags, i get the following error in /var/log/messages:

If i remove / comment out any one pdoentry, the error goes away.
master idx="0" has no error, idx="1" - idx="3" have the error.  
There seems to be a limit of max 10 entries?
How can i work around this?

 

It is not uncommon for devices to have a limit on how much data they can exchange.
But do you need all of those PDOs? I guess not.
So just delete the ones you do not use from ethercat-conf.xml

These servos have so many functions and parameters, that 10 is a really small limit.
Is there a way to split the pdoentry tags into multiple pdos?
Or change them during operation, e.g. have a different ethercat-conf.xml during homing vs. normal operation?

I don't know that, but if you have static data you can set that using the SDO instead.

is this the <initcmd> tag?

Like this place before all syncmanagers in ethercat-conf.xml
Only thing to say here is that the byte order is reversed. Least significant byte comes first.

You can try to read out and set manually using
