But looks like producing something with EtherCAT requires licensing. Well, EtherCAT and CANopen support might be secondary because of really expensive hardware. But support for serial absolute encoders looks very reasonable. No complicated gantry homing, no rotor homing for BLDC component with 7i39 or similar hardware. 2013/5/30 Eric Keller <[email protected]<https://mail.google.com/mail/u/0/?view=cm&fs=1&tf=1&[email protected]> > > I am a somewhat disgruntled consumer of so-called "modern servo > drives."

We have a very precise machine that uses that interface. Can not but agree here. 2013/5/30 Peter C.

I guess 7i43 is useless for BiSS?
