[etherlab-users] Yaskawa Sigma-5 no Vendor ID or Product Code

[Henry Bausley]

I am attempting to use a Yaskawa (SGDV-R90FE1A) Sigma-5 amplifier motor
combination. It appears as if there is no EEPROM which seems strange to
me.  I generated a binary file and attempted to write it into the EEPROM
with the ethercat sii_write -p 8 -f Yaskawa.bin command but afterwards
there still no Vendor ID or Product code.  The ethercat -p 8 -v sii_read
command returns nothing.

The Yaskawa app engineer told me that they have had problems with
masters that need information from the EEPROM and he would have to
convince the engineers in Japan to change this.

My question are. 

1.) Is it possible for a device to not have EEPROM data and be ethercat
spec compliant?  

2.) I was also told that this device has passed the Ethercat Conformance
test.  Is this possible without anything in the EEPROM?

3.) Has anyone used this drive with the etherlab master? I suspect no
one has.




Below is a printout of the ethercat slaves command.
