Maho MH-C 700P Achsen bewegen sich dauerhaft Indramat 3TRM2

Without the 7i77 connected, I calibrated the axes in the Indramat zero point, they stay exactly and don't run away.

That is wrong for velocity drives, they must spin slowly when there is no input signal.
Do the motors have tacho generators?

Hello, attached are the pictures of my axis calibration and Hal Scope. The axis moves in 1-2 hundredths not tenths.

Hello, Indramat servo motors are installed. I think these should forward a speedometer signal to the 3TRM2. Before I did the zero point shift, the axes moved even more. I won't be able to return the Indramat to its original setting because I haven't noted the zero point or the poti setting.

This milling machine has two analog inputs per axis on the Indramat servo amplifier. One input from the control, the other via the original feed potentiometer including rapid traverse switch. I have completely separated this input because I control the feed via Linuxcnc.

Hello, thank you very much for your tips. Unfortunately I can't get any further on the matter. Can anyone do something with the images I sent or has an idea for solving the problem?

Thanks in advance for any efforts

Are the motor tachometers connected to the drives?
This is necessary for velocity mode drives to work properly.

I asked the same question, never got an answer.
