General Mach Discussion / Re: Lots of Questions- ac servo spindle, macros, and tool changing

Hi,
depending on the details of the servos then you will need a analogue controller. There are not many choices.

Kanalog
CSMIO/A
HiCon Integra
Gallil- various models.

All of these work with Mach3. The Gallil and Hicon work with Mach4 and the CSMIO/A is supposed to but their Mach4 plugin is buggy.
My advice is consider Mach4.....all development ceased on Mach3 five years ago and eventually it will tip over...so...'go mad now and beat the rush'

Thanks Craig. How do I determine whether it's running digital or analog? DC servos are yellow cap, a 5M and a 10M.

General Mach Discussion / Lots of Questions- ac servo spindle, macros, and tool changing

« on: December 05, 2018, 09:19:44 PM »

The forum search is currently down so I don't know if these topics have been covered (I'm sure they have).

I have a Daewoo Puma 6 that was built in 1984. It was working well up to a few days ago, there is a EPROM issue and I'm trying to track down a way to have new chips burned. Fanuc is telling me that I need to get the chips from the manufacturer of the machine, not the controller. I am thinking I would like to change the system over to Mach. I currently run Mach3 on my CNC router and have been very happy with it.

Current setup on the lathe-
Fanuc 6T Control
12 position tool turret (hydraulic driven with encoder)
Foot operated drawbar and tailstock

My concerns:

The spindle is a 15hp ac servo. There is nothing wrong with the servo drive but I am not sure how to go about controlling it. I do a fair amount of threading so this is important.

X and Z are both Fanuc dc servos, same as my router. I feel I can look at them as a reference for the lathe.

Tool changer and macros...

I need to be able to run a program start to finish with the ability for the machine to change tools. How is this accomplished?

I'm hoping there are a couple individuals out there that can give me some guidance on this or point me to someone that can.

Thanks,

Erik

General Mach Discussion / Kinda lost on servo setup- how can I control?

« on: June 08, 2017, 09:32:29 PM »

I'm pretty new to CNC and need some help on getting a machine running.

I recently bought a CNC router and I use Mach3 to run my programs. Works great.

I ended up with a CNC lathe last week, it's in need of an overhaul. Being new to CNC, I assumed that since the lathe was running servos I could just order a set of what the router has and be golden. Wrong. I ordered two gecko320X drives, smoothstepper, c25 terminalboard, and a 1200w power supply. Get into the lathe today and upon further inspection the servos are AC and at .9kw each, I would probably be under powered anyway.

I'm not sure how to proceed. The servos are Fanuc b6/2000 and require:

1)
2) 0V Reference voltage
3) IRC Note) Phase R motor current signal
4) ISC Note) Phase S motor current signal
5)
6)
7)

9) 0V Reference voltage
10) 0V Reference voltage
11) 24VC +24V power
(with tolerance of ±10%)
12) 15VC +15V power
(with tolerance of ±10%)
13) -15VC -15V power
(with tolerance of ±10%)
14) 5VC +5V power
(with tolerance of ±5%)

Can I even use the smooth stepper to get these voltages and how do you get negative voltage??

I'm thinking I may be better off to sell the AC servos and swap out for DC?

Any help is appreciated.
