please check the realtime capabilities of your system.
Taskmonitor - you should see jitter times <100us (if you do a reset by rightclick in the Ethercat Task)
On realtime capable plc's ( ->Control Win is not possible to use!!) the Sanyo drive will work with 20% Offset (Default)
and no matter 1000us,2000us,3000us,4000us Taskcycle(Ethercat) and DC clock should the be the same setting -> use the same sync time than the ethercat master Task is.
our system is ok about realtime... unfortunately it isn't very fast, infact for us and our applications it's ok a jitter <=300us
It's ok about Task Etchercat cycle and DC too.
In these days we have done another test:
Our board has an Ethernet switch (MICREL) and two eth port, the first one is connected to the lan (then from codesys i can choose it through scanning devices), and the last one goes to Ethercat devices.
Now i'm doing tests using board and Sanyo driver.
If i send positions (sanyo is in csp), for example at 2ms ETC Task and 2ms DC, drive loses some steps, but if i remove the cable which connects board to lan, it loses less steps!
Maybe is there some particular config to use? Is it possible that Ethercat comes into conflict with other packets in the Ethernet line? Probably this is a part of the problem...
but i cant understand why if i set 6ms on ETC Task and 6ms on DC, driver goes instantly in fault...
Thank you for your patience,
