General Mach Discussion / Re: Servo Motor question

« on: March 11, 2011, 03:30:36 AM »

Hi again Hood et al; I have attached some specs for ADTECH servos, I don't know much about the manufacturer, but they seem quite price competitive. I was wondering if you could let me know your thoughts as to what you would select for the VM760. I am thinking of these:
ACH-13100CC Servo motor,1000W,2500RPM,4NM,4A
or
ACH-13100CC Servo motor,1000W,2500RPM,4NM,4A(Withbrake)
With this driver
QS6AA030M Servo Driver single phase or three phase 220V

Is 2500rpm fast enough? the servo will be direct coupled to the ballscrew

BTW Hood, I saw your latest post on the SS forum, I saw exactly those symptoms this arvo

Cheers

Dave

I have pretty well decided to go with the VM760 machine frame below. I wont be buying the servos vfd or spindle from the manufacturer, since I think I can do better elsewhere. They have been pretty good to deal with so far, they are happy to provide couplers and make the motor mounts etc to suit the servos and spindle motor that I choose.

This is to import the machine from Taiwan, so there will be another $3000.00 in freight and port charges etc.

The VM760 is what I am leaning towards too, It is quite modular in that you can buy anything from the base machine without motors ATC etc upwards.

Thanks for that Hood, It's been a while! Sorry for being lazy and asking, I should have done my homework, but I needed to get back to the guy quickly.

Thanks again

General Mach Discussion / Servo Motor question

« on: March 01, 2011, 03:19:28 AM »

Hi I am looking at buying a mill which is already a cnc mill, it had the option of a built in Chinese CNC controller, but I asked them to quote the mill with just the servos and drives.

The Servos are AC servos, and I am wondering if there would be any difficulty interfacing them with Mach3.
Here is a link to the manual for the servo drives

I have had a lot of experience in the past with steppers, but servos are a whole new ball game to me.

Thanks
Dave

I have about 6 versions of this manual, most are missing the last section with the diagnostic error codes, this one is the most recent, and is the only one that is actually from Huanyang
