[etherlab-users] Yaskawa servo drives SII

[Ravi Chemudugunta]

I am in the process of setting up and playing with the Yaskawa servo
drive (sigma five), I plugged it into the master, good news is that it
shows up as a slave, but I can't get it to do much more else.

Doing some goggling on the topic, I came across this thread

http://lists.etherlab.org/pipermail/etherlab-users/2010/000939.html

I get more or less the the exact error, as mentioned, being:

"
EtherCAT ERROR 0-0: Error on last command while reading from SII word
0x0080.
"

The post also mentions that with the newer firmware, this error does go away.

"
2.) In addition, I just received another drive from Yaskawa and they
have updated their firmware(3.01 now) and the SII content size error no
longer occurs. This one is visible without the latest version.
Hopefully now I can get this drive to servo motors with the etherlab
master.  I will keep you posted.
"

Will the drive work without the 3.01 upgrade? or is the error purely
an annoyance?

Generally speaking, if the slave configuration fails, is it possible
to still use reg_pdo etc. to manually setup the pdo's or make sdo
requests against the object dictionary (since those address are known
through a paper specification)?


cheers,
