Hi,
You should enable the debug mode to understand that happened just before
the error
--------------------------------
$ ethercat debug --help
ethercat debug <LEVEL>
Set the master's debug level.
Debug messages are printed to syslog.
Arguments:
LEVEL can have one of the following values:
0 for no debugging output,
1 for some debug messages, or
2 for printing all frame contents (use with caution!).
Numerical values can be specified either with decimal (no
prefix), octal (prefix '0') or hexadecimal (prefix '0x') base.
-------------------------------
Level 2 of debugging is very (very) verbose, so you should begin with
level 1
$ ethercat debug 1
Concerning "DefaultSize=0" for SM2 and SM3, I think that is normal,
because I have also such a value on my Kollmorgen AKD drive in torque mode.
