Brother TC-225 / TC-229 adventure!

the axis motors definitely have model numbers. they are not brother specific. sanyo 25bm... the drive also has a number. that one IS brother specific. but, remember, the people buying these will likely be repairing a brother, sooo, just list them as tc225 parts with whatever numbers you find on them.

fasttobuy2012 is a good source for delta. they i think are on holidays (all china is) right now though.

the spindle drive and motor work perfectly with linuxcnc as is. dont need to change them. dont think i posted a vid for it here, but i had a "simulated" tapping cycle going and it was happy right up to 6000rpm.

you keep repeating this over and over... yet offer no actual advice on how to actually tune it better..

the general conclusion here is that with a velocity loop in the 50-100hz range, without jerk control linuxcnc cant tune out the resonance.

"tolerance" was fine. it would track better than a thou at any speed or acceleration. this was never the problem. harsh vibration was the problem on acceleration.

its a total waste of time and money to attempt to make them work, when you can sell them and buy new high end servos for a small amount of money.

The drives where not properly tuned with the original control, Y had some weird overshoot and resonance, i will try to tune that on the drives with the original control.
The thing is with the original drives and a mesa 7i97 i have laying around i can have a go at trying to tuning them pretty inexpensive, and i can always trash that idea and buy new motors and drives. Hopefully with the help of the knowledge on this forum we can get it to perform a bit better.

oh, you should definitely given them a try is everything is operational. just expect to have resonance issues.

Hello. I bought a spindle servo from brother 225. I can't figure out how to connect it to 220v. Or is it necessary to connect 3 phases of 200 volts to the transformer? This is necessary for my cnc project. If I connect the servo driver to 3/380 volts or so it might break?

My brother 225 has a transformer, it can be wired for 3 phase 380V (400V) input, that should be a Y configuration if I'm not mistaken. (Delta config for 220V input)

Unfortunately I don't have a three-phase transformer. I want to figure out how to connect one phase of 220 volts to the terminal blocks of the servo driver. And I read earlier that one of the forum participants was able to start it from a single-phase voltage.
Which terminal blocks R S T and r s. Connect phase and neutral?
