Alternative Servodrive for Indramat Servos

Dear Folks,
this is my first post but not the last
I´m planning on retrofitting my MAHO Mh600E ´89
It´s my main working machine in the shop and doing quite a good job. But the Ballscrews are little worn out and i´d like to run some better paths on it. It´s kinda time consuming to upload a 150kb file...like 5 hours.

I´d like to renew the ballscrews and use the old servos, because they are still working and fit.
If someone knows how to hook up the Indramat drives i´d keep them even too. When i look at the wiring of the drives in the cabinet there are like 10 wires each axis and some of them are crossed over and it´s not clear what each wire does. If someone would have a clear Pinout that would be great.
Or is it possible to use a modern driver with the old servos ?

hi
you can use simply cheep servo systems
BUT does the Maho from 89 not got liniar scales
a real good and cheep retrofit is to go for 12Nm Hybrid this will lead in a good machine also and takes the cost down to 25%

Are they easy to tune ? i´m scared they are not that good and i´ll waste money on the 7i77
If i can get some help i´d love to use them.
The Maho has glass scales and this omnious "exe board" can i use that with the mesa cards ?

Yes the "EXE" board converts the sine/consine signals from the scale to
quadrature signals that a 7I77 (or any standard quadrature input device)
can read.

Velocity mode drives are usually fairly easy to tune

Okay that´s great.

I´ve bought this:
1x MESA 5i25 Superport FPGA based PCI Anything I/O card
1x MESA 7i77 Analog servo interface plus I/O daughtercard
1x cable

Now i need a computer running linuxcnc and some magic.

Is there knowledge about wich "Achse" Axis is wich ?
Achse 1 == X-Achse ?

Here is a copy of the indramat 3trm2 manual. This is what in running in my Maho MH 600c.
The drive tuning should be good as is. So you only need to tune the position loop on linuxcnc.

Thank you very much Henk,
those are drives that i have on my machine.
Does anyone have a clue how to salvage the relais board ? I mean something like a pinout ? There are cables with numbers like 325 or 311.

Do you have the machine electrical documents/wiring diagrams?
