This machine has a Contour 3 controller.
At first i want to move all axis. Then the spindle and at last the toolchanger.
I want to keep the old simens servos with the bosch servocontrolls. I also want to keep the linear Heidenhein encorder. They are still in a good shape and still work.

A list of all the components on the machine i want to keep to move the table:

Heidenhein LS904

Bosch tr15-xa-140-230V
Simens 1HU3071-0AC01-Z

The original contoller (in the control cabinet) has 56 Inputs and 92 Outputs.
I am going to ned an analog Output for the servos and a sin/cos (1 Vpp)u Input for the linear encoders. The servos also have some encoders on them, but these are only for the velocity.
Later i am going to need another analog Output for the spindle.

In my mind i am going to use a mesa 7i80HDT as a base for the daugthercards. For the spindle and the servos a 7i77 and for the linear encoders a 7i85, because that one can read the 1 Vss signal.
For the other I/Os i would use some 7i70‘s and 7i71‘s.

Please correct me, if i am going to make a mistake?

No, Mesa 7i80 does not go with 7i77 and 7i85, the Mesa 7i92TM goes with those. 7i80 is 50 pin, 7i92 is 25/26pin.
There are other options also, the 7i77 is hard to find so a bit more searching is needed, on the 50 pin stuff i can not help, but for 25 pin stuff i used a lot, here are some options:
-7i97T it is roughly the same as 7i92TM with 7i77, with 7i85 or even better with 7i74 as this needs plain LAN cables to wire the 7i70 (48 inputs) and/or 7i71/7i72 (48 outputs sinking or sourcing), or 7i84 (32 in and 16 out)
-7i92TM (notice the M, makes it directly plugable into 7i77 so no need for IDC26 to DB25 cable and adapter), with 7i85 OR 7i74
-7i96S (step/dir and spindle) with 7i83 (analog outputs) and 7i85 (encoder and SSerial) for 7i70/7i71/7i72/7i84
-
I think there is also 7i93 IRC should have 3 of IDC26 headers, but not sure, should be same as 7i92 with more IO. Again, do double check this.

Thank you for your help. I will look in to the availability of these cards and then i am going to decide. But the 7i97T looks promising.

Next week i will recive the electrical manual and then I can determin the exact number of I/Os and wich signal they need.

Hello again!
I finally received the drawings of the electrical, hydraulic and air circuits. Now I will count the exact number of I/Os. Then I will make a list with the exact signal of each I and O needs. It would be nice, if someone could correct me on my choice of mesa cards.

Here they are (lower resolution), maybe I can help someone with this:

Hi Mbrandt,

I am using the Mesa 7i97T for 4 seperate axes with Heidenhain encoders and Tacho DC servo motors on my milling machine.
My servo amplifiers get the setpoint +- 10V and the Enable signal from the Mesa card. Very simple and straightforward. The inputs from the Heidenhain EXE ( I would assume, that your machine has the Heidenhain EXE card/units on board) are also easy to connect. The read-out of the positions worked immediately.
I bought the MESA card from EUSurplus in Portugal - the only source, where it was available in Europe, Highly recommended dealer.

Best regards

Hartwig

Hello Hartwig,
Thank you for your reply. I think my machine has some sort of EXE, its a board and the name is NCP59. But i dont know where to intercept the TTL signal from it. There is a version of this board with an extra digital output, but i dont have it on my machine. And buying 3 Heidenhein EXE is a step back. I would like to use a modern version of that. Maybe a 7i85S or someting like that?

And the Suplier you sent seams good and I will buy der 7i97T from him.

Here is a picture of the NCP 59:

Hello Mbrandt.
I have used the following type of "HDH Exe Platine" with 3 channels.
www.ebay.de/itm/204779209363?srsltid=Afm...Gj67v4RUzT0PLvOgckrB
Very simple and very small. It fits between the glas scales and to the MESA directly. For mine I have paid less than 200 Euro.
