linuxcnc mill closed loop control with Chinese vfd and fanuc spindle

just a bit of linuxcnc fun

closed loop control of a spindle just shows how easy it can be

the Chinese vfds auto tune these fanuc motors in about 3 secs and are so easy to set up.

best I have ever seen.

a yaskawa vfd failed with this motor and schiender altivar 71 was twice as hard to set up.

highly recommend this option for your retrofits.

this was bought from

At20 series 11kw
cost me just over 200usd

encoder cost about 70usd

Basically you did that mount because the fanuc proprietary encoder was only working with their drive? Nice idea, I like it! Congrats!

wow, what are your voltages at 50hz and at maximum?? what model is the fanuc motor???

[philiplydin]

what specifications does the vfd need for this type of linuxcnc pid loop to function, what signals are sent to the vfd when its orienting? maybe you can send your email so we can discuss.(:

Any recommendations on parts / setup for a compact linux cnc 3 axis mill build in AU / NZ?

Hi, are you able to do spindle orientation with that setup?
