Hello everyone,
I figured everything out. I will list all the connections I made in this topic so that others can benefit from this.
The setup is for an IRT SA CH-2005 Neuchatel servo amplifier with the 5i25/7i77, one servo motor and one mpg.

TB3 ENC 0

QA0 ---> A (from servo amplifier)
/QA0 ---> /A
GND ---> GND
QB0 ---> B
/QB0 ---> /B
+5v ---> nothing (has its own power)
IDX0 ---> Z
/IDX0 ---> /Z

TB2 Field:

1,2,3,4 ---> 12v power supply (W1 in default left hand position).
GROUND ---> GND and END SWITCH 1 & 2 (from servo amplifier), MPG 0V (from MPG)

TB5 DRIVE 0:

ENA0- ---> Torque Ref
ENA0+ ---> Torque Enable
GND ---> +Speed
AOUT0 ---> -Speed

I/O TB7

16 ---> MPG A
17 ---> MPG B

The mpg was installed by enabling mode 3 in PNCconf.

Everything works but there is one thing that bothers me.
I can't select the jog increments in the axis GUI.
Any ideas on how I can achieve this? (maybe I should start a new topic in the GUI section?)

Thanks a lot to everyone who replied in this topic

Do you mean that jog increment selection in Axis is disabled, ineffective or unaware of external changes?

First a big thank to PCW! I wish you a happy new year... Not as sure with the Drive Control and the reference switch as these are to be connected to the 7I77 properly.

Hi, now I have a problem with the servomotors. I have connected the servos according to scheme. If I move the Y-axis, it works too. If I now close the Z-axis, the Z-axis moves totally uncontrolled. When I move the Y-axis by hand, the position in the terminal changes. If I close the Z-axis and move the Z-axis with my hand, the position in the terminal moves on the Z-axis and Y-axis. Does anyone know such a problem? Possibly. is it on GND .. I'm not on it unfortunately ..
