How about sending some of us those cash who can help solve your problems :)

Kidding aside, you can post your problems and I believe some of us can help along the way.

Hi mactec54,

Do you think a standard SGDA Sigma I drive (servopack) can run this 750W AC servo motor?

Mactec54,

I agree it is not the best choice of a servopack or servodrive, it being a special oem drive. I have the option to return it or make it work. I prefer to try to make it work as it comes...

Hi Grubma,

Ok, I tried the SVMon v2.1 and I was able to read the registers of the servopack using what you advised. As you said, aside from the registers, I was not able to do such things as jog...

Hi Mactec54,

Thanks for the advise re SigmaWin+. I'll try to find the DOS version.

Actually, it is Yaskawa Tech Support who advised me that this particular servopack is an OEM network driver...

Thanks for the advise. The hand held digital operator may work but I still doubt as the 1CN connector 20 pins is not published anywhere in Yaskawa manual. Also, this servopack being an oem version...

Hi Grubma,

Thanks for the 1CN and 2CN pinouts drawing.

Can you tell me where you were able to get these pinouts drawing and maybe I can download the more complete manual for that?

Were you...

Carlos,

Thanks for trying to help. I have been to that site already and downloaded all relevant files.

However, as I have said already, the Yaskawa technical service support group had advised...

Can you provide some websites or links on how to drive ac servo motors with VFD?

I want to read up more on this before actually hooking up a VFD to ac servo motor as I have read somewhere in other...

I cannot get any drawings for the machine as it was scrapped by the semiconductor company that closed down. I did went thru all station numbers but still not recognized by the SigmaWin+.

You are...

I tested the servopack with the PC using both SigmaWin+ and SVMon but still no luck. Double checked all the connections and the result is still the same.

I guess this servopack really works...

Ah, thanks for info. It is utterly stupid of me to commit that mistake :)

In my frustration, I cut off the temporary soldered wire between motor encoder and 2CN. Got to resolder and try it again....

Yes, the communication protocol is:
9600 bps
1 start bit
7 data bits
1 stop bit
Though I made the mistake of turning on XON/XOFF control.

Do you think this will make a difference?

If the comm cable is disconnected, and if I try to connect online, then it says servopack not found.

My cable is working on Com1 RS232.

Thanks for the info. I have the same DR2 servopack manual and it is for the standard Yaskawa DR2 servopack.

Unluckily, Yaskawa technical support has confirmed that the DR2-08AC-NY41 series...

Hi Grubma,

Were you able to solve your DR2 servopack problems?

I also have some DR2-08AC-NY41 servopack and Yaskawa tech advised that these are special OEM servopacks that are network drives...

Hi Jubee,

Thanks for the answers. It is much appreciated.

Regards,

Interesting CNC Bender build.

The 500 lines limit is for the GCodes. Mach3 can be used in multiple computers and controllers with just one license in a DIY or hobby shop though if used in...

Just to illustrate and let you know the pitfalls of using Chinese characters without understanding its meanings. :)

Below are 3 very similar Chinese characters that sounds and pronounce almost...

Looking at your attached picture, I can tell you that there is no correlation at all between the alphabets and the Chinese characters. Web translation may help at times but we all know that it is not...

You will have to let us know what file format you are using in your CAM program as well as the drawing program of your daughter. Most will use a DXF.

If you want, you can PM me and let me know the...

Word of caution:

Based on the discussion I have with someone in UK who had recently imported a CNC Router with Mach3 cnc control from China, the implementation is not that good. The China Mach3...

The recent discussions about various CNC controllers are very interesting.

Personally, I have not used the other cnc controllers except Mach3. I am no expert of Mach3 but I will try to make some...

Hi Jim,

Thanks a lot for the offer to send me the Type3 dongle. I greatly appreciate that.

I have googled and d/l the sentinel sw and will let my friend try it. Hope it works out.

I will let...

Hi,

I know many of you have the Type3 sw with dongle from China and I need a favor for a friend.

The friend imported a CNC router from a China manufacturer (not Excitech) and it comes with a...

Hi Kent,

Thanks for the info on USBCNC. Casual glance at the specs shows some concerns:
75 KHz max. frequency
Pulse width 5 uS
Limited inputs and outputs (?)
Extends of supports and new...

Hi Jubee,

Can you tell me the specs of the eeePC? What model? Is the Touch Screen an addon?

Am I correct that the eeePC doesn't come with a parallel port, and thus you are using the Smooth...

Troy,

Here is the terminal assignment of the YKA2811MA:

Based on the spec sheet of the YKA2811MA, I believe I said the Power Supply of 60 to 130v AC is for the Stepper Driver. I didn't say it was for the Stepper Motor.

Anyhow, you are correct that he...

If you are referring to the Yako Stepper Driver, I believe there are 2 YKA2811 models. The YKA2811MA is a stepper driver with microstepping while YKA2811S is with full and half stepping only. Both...
