help with ethercat and omron drives

The best thing to do is to sit back and wait for a reply that he has fixed it

you shush

Not sure what P value in the ini.would do regarding servo drive tuning. this is position control ethercat.

I don't see any P value.

You are right. There is no pid control loop for the axis in ini or hal.
It's all in the servo drive.

It can help to lower P in the servo drive for the noise. But you said you tuned them, so

Yeah, later today I'm gonna reconnect the omron software and see what's up. its possible they got wiped somehow, but seems unlikely.

I don't really thing there's anything on the linuxcnc side that could be at fault though, its not even commanding a movement yet, just enabling the drives.

You can go into halshow and look at some of the cia402.x.stat pins like if stat_op_enabled is set.
The drive needs to be in op_enabled to start moving. It should be just to jog and it should move.
You have the position commanded and actual and more there to get the state of the drive.

Adjusted motor tuning, its fine now. moves and is happy. Still need to tweak the y a little.

It does seem that tuning in the omron software is not *quite* the same as running under position control. Didn't lose anything, just small tweaks. X was the howling one and it still tracks within 3 microns during acceleration. The Y has 2 microns lad in straight motion and 6 during accel. Bigger motor and MUCH more mass. Just trying to keep it "stiff" as possible. Anything under 10 microns during accel is a win. (this machine does high speed surfacing).

Anyhow, break time, I'm very happy. thanks for all the uh.. moral support? hahah. I get frustrated a lot when the instructions are missing big blocks of important information. I think I need to write a "ethercat setup for dummies" post so other people can follow something a bit more straight forward. The "implied prior knowledge" is what really turns people away from linuxcnc in general.

Told you, was just to sit back and wait
That milling machine looks and sounds great.

Can you share the ecat-conf.xml file you ended up with? Can help the next guy out.

And don't forget that "ethercat for dummies" post, greatly needed.
