Hi to everyone.

This machine is new to me and its my first CNC.

I bought it as is where is and was able to get everything moving after a couple of weeks. Research I did before the purchase led me to Masso and I would consider changing out the controller if possible.

It has Indramat A/C servo drives and 3ph servo motors and the Z axis appears to have a holding brake.

If I was to go this way I would use a single router spindle, (maybe an ATC upgrade later) and remove the boring head as it is no use to me. I would also like to add a 4th axis at some stage.

Of course none of this is set concrete but I would like to know if Masso would be able to connect to these servos.

I'm located north of Newcastle AU.



Regards Peter

Provide a link to a pdf copy of the driver manual so that we can check out the input and parameter requirements.

Regards,

Arie.

Looking at the top photo, they seem to be model number DKC11.1-040-7-FW

Manual here: https://www.indramat-usa.com/wp-content/uploads/2018/01/DKC01.1-DKC11.1-Project-Planning-Manual.pdf

Section 1.2 of the manual says:
The drive controller DKC11.1 represents a particularly cost-effective solution. It is used as a servodrive with analog speed interface and integrated actual position detection

From my (very) limited knowledge, I think that means Masso won't be able to control it but I'll let the more experienced members confirm that.

Thanks Derek.

You beat me to it.

I believe that is controlled through the (X1) socket which are not utilized on these servos.(section 4.3)

The (X2) function on these servos are not optioned at all.

(X3) is where I need help with. At least this is what I think!

All advice appreciated.

Here is another angle.

Page 4-25 of the manual says X3 is analog input +-10V on Pins E1 and E2. Again, I m not in any way saying these will definitely not work, but from what the manual says, it s model DKC01.1 that accepts digital step/direction signals which is what Masso needs. Manual says on X2 is the positioning or stepper interface , which as you say is missing on these drives.
I think this is one where LinuxCNC and a Mesa board will work. I would post these images and the link to the manual over at the LinuxCNC forum to see what the guys there say.

Peter,

From a quick read of the PDF

Figures 4-30 & 4-32 provide the information for S&D control.

But looking at the Contents list I can't see any info on parameter settings required to put it into S&D mode. Maybe another manual?

Regards,

Arie.

Hi Derek

I believe those inputs (terminals 1,2 and 8) are from the potentiometer used to slow down the feed rate manually through the controller to the AC servos and the VFD.

Hi Arie

Those figures relate to X2 functions which do not apply to the DKC11.1 that I have.

Fig. 4-37 I think is what I have to work out and if and how they can be connected to a MASSO.

Peter,

Had a closer look at the PDF and sad to say that your drives won't work with MASSO as it doesn't have the stepper interface module, that is only available in the DKC01.1 version.
The drive controller DKC01.1 is used as a:
servodrive with integrated position control
servodrive with analog speed interface and integrated actual position detection
servodrive with stepper interface.
servodrive with electronic gearbox function
The drive controller DKC11.1 represents a particularly cost-effective solution. It is used as a:
servodrive with analog speed interface and integrated actual position detection

Regards,

Arie.

I might look into the Linux/Messa Convertion but I will probably use it the may she is.
