Is the cylinder controlled by -10 volts advances and +10 volts retracted position 0 volts gradually descends
Note: I am using translate google sorry for any inconvenience

Analog voltage from inductive sensor? Is that the position sensor for the ram/cylinder?
Maybe using the values from that sensor to home or to check and retract the ram at LinuxCNC start?
Also use the value from that sensor to stop the machine from moving anything else if not in upper position. I would strictly tie this to motion feed hold if this is punch press so the part can not move until the ram is up. This i think is a must on such machines. Also to make sure the material has stopped before ramming down...

Thanks for the feedback
Yes =>  inductive sensor
Yes=> position sensor for the ram/cylinder
Yes=>Maybe using the values from that sensor to home or to check and retract the ram at LinuxCNC start

I am currently in the electronics lab, I will do some simulations and post them here for everyone to see. And when I go to the machine I will already have a theory to be applied. Thank you very much to everyone, I am available if anyone needs any more information about this machine or the process I am doing with the electronic boards from the manufacturer Mesa 7i77.

 

I will attach the technical data in case anyone needs to work with this type of machine.

Repeat accuracy ± 10 µm
Voltage output 0 ... 10 V
