beta bulleri for retrofit?

Hello everyone, I got this machine through an auction, it is in good physical condition, but with a controller that, even though I have the parameters, will not perform referencing, simply the switch that supplies power to the drivers will not stick if I hold the z axis, it goes up to the limit switch, turns off the drivers and an error axis error appears. The motors are dc servos with analog input for the drivers and have 500 pulse encoders. my question is whether the Mesa 7i96s+7i77 can satisfy that the motors remain and that the rack ATC will somehow work later. Thanks in advance for your future support.

there is a schematic but very weak, I can find out which cables are for encoders and analog inputs for drivers, which is enough to maybe tune the motors, but there are a lot of inputs and outputs of some inductive sensors and the like, so the schematic is a bit useless, I would have to see what activates what. I'm worried because maybe the switch for the drivers is faulty, (see the attached video) plus x, y don't move and I had to remove the driver for z because when I turn on the drivers and hold the z axis it goes up or down quickly.

I managed to change the parameter for the z axis to change the poles of the motor, I slightly reduced the trimmer for ``speed'' on the driver and now it wants to turn on the power for the drivers, all the lamps are green and the motors are energized and do not turn...however, according to the instructions, it asks for the first referencing, so anything else unfortunately throws an error and the referencing will not start, I will also have a screenshot tomorrow in pdf or image format of schematics, I guess I will have to to do a retrofit
