The DC servo motors are not interesting now. Maybe I can play later with. Here in Hungary there is one company who produce DC motor drivers. Check it on CNCdrive - motion controls
The ISTECH is one...

I just ask you, becouse as I told the Wasino wich I want to retrofit has 2 yellow cap servo motors with good drives, and we also used 1 Kiwa excelcenter milling machine with exact the same 3M Fanuc...

The Wasino is built to reach up to 4000 RPM but we dont use more than 2000 RPM. Maybe I try to limit the speed up to 2000 RPM, and with this becomes easyer to have torque on 300 RPM like a minimum...

The method of the retrofit was that I purchased(already tested with servo motors, on table) an SZGH 1000 Tdb controller wich was working with step/dir for axes, and 0-10V for spindle control, and...

If you have an experience with sensorless mode it is great. I only use the VFD in to moove rollformer machines(for our own production)but it is far more simple then a lathe or mill. Becouse of...

You think that a sensorless control without feedback is a right think to use a Fanuc lathe spindle, and have a good torque on lower RPM?

Thanks Jim

In a meantime I was seaching more about spindle drives, and the best thing is to have a drive with encoder feedback connection as the Fanuc has. There are a few chinese product like...

Dear Jim

I was study the VFD controllers and lookin arround youtube, but everyone told a different. I realize that it not can be as with original Fanuc driver. I think that ACI Zhufeng has no...

Dear All

I am newbie in this field with Frequency drives. We have one Wasino cnc lathe wich has a bad Fanuc controller, and I decided to renew it with Chinese cnc controller and with VFD spindle...

Dear all

I have bought the Stama MC-010 machining center(same as Fanuc Tapedrill Mate) and I have some problems with tool change. Let me summarize the symptoms:

Hi Heavy Metal

I have machined before with simple F100 ,but of course I try F100. and F0,1 too,but when he coming to execute first line G01 he stopped.

Hi Mike

I used to be machining before with this lathe,and there are no possibility to work with feed per revolution,only feed per time.(the feddrate override was inactive also)
I try to put M48...

Hi All

We have a lathe wasino with Fanuc 3T.Be able to start up,go to zero,start machining,execute G00 but when hes coming to G01 he stopped and not move.
I checked parameter and the feedrate is...
