Elumatec SBZ 130/01 retrofit

Well that was uneventful !!! Just did a bench test of the 7i76e and it took me all of the 25 minutes to have it up and running. I already had the kernel installed on one of my laptops using Linux Mint.
Used the Pncconfig to make a usable config, strange that it asks for parallel port, so i had to manually remove the lines pertaining to paraport and it worked. checked the outputs with a multimeter and they do work properly.
This was on a Lenovo T420S, and i am getting some really bad latency on it, 11300000 to be exact on the servo thread so the card would error after a while. (yop that is over 11 milion). I have some computers that can do 3 to 5000 so i will be using those on the machine.
Now, PCW if you read this, thank you for great products and support, and i have a question: can i connect a 7i92 directly to a 7i77 without a cable? As far as i gathered from reading, the 7i77 should be connected on the other port, not the DB25, or am i wrong?
I am off to watch the Grand Tour (car show) and get some zzzzzzzzzz.

Yes, you can connect a 7I92M ( M for Male DB25 ) directly to a 7I77

Thank you Peter.

Finally started working on this machine, got rid of the old controls and computer and mounted the Mesa cards. Getting familiar with all the inner workings as much as possible on a non functioning machine, and planing everything humanly possible upfront, so here is a short burst of info:
-motors have brakes, tacho and serial absolute encoders
-long axis has a separate absolute encoder with separate rack and pinion, brake on the motor and pneumatic brake on the rails, had separate control
-spindle looks like having 1to1 ratio on tool 1 so good for rigid tapping, can not check other tools for now
-tool changer has another brake and a clutch inside
-a lot of pneumatic valves, relays, end switches, pressure sensors, clamps etc

After a detailed check, found out that the long axis encoder has "direction" wire, others do not.
So it looks like the serial absolute encoders on 3 normal axis and spindle are usual "clock +-" and "data+-" type, so hopefully they can be made to work with 7i74, and this is the first thing i have to check.
The setup is: 6i25=>7i77&7i74=>7i70&7i71, already flashed with 5i25_7i77_7i74.bit file
---how do i go about using the 7i74 as half SSI and half SSerial? I need 4 encoders and 7i70 and 7i71, nothing more

Attaching some pictures of the old and the new.

Tom
P.S.
Attached pictures of the encoders, the one on the long X axis is not the same as the other 4, it has a wire labelled "richtung" meaning direction???

Thank you very much Peter.

Nice nice NICE !!!!
Thank you very much Peter, will give that a try tomorrow, now if only i had a simmilar config to test encoder reading.......ah wishful thinking!
I forsee a lot of reading.........of a thread here about serial encoders and 7i74, over 10 forum pages long. Oh joy.
Today i wired the 3 phase AC servo drive that drives the spindle to the analog output 4 of 7i77 and made it run on both directions, speed control working properly and working enable. Will move it to Aout5 tomorow as it has separate enable.

Wiring advice:
When connecting enable signals to 7i77, before connecting the enable wires, use a 1Kohm ( i used a 470 ohm ) resistor acros them, it should enable the drive and the motor should start turning slowly. If that works, connect those 2 wires to the 7i77 enable, but wire the resistor in series with one of the wires. That way even if the polarity is wrong, it will not destroy the 7i77 optocoupler.
PCW correct me if i am wrong on the above.
Again thank you all.
