Hurco KM3P retrofit

I am not fully understanding what you mean. Are you asking for a pin that will release the axis brake when the axis is moving?

Typically the brake only exists to stop the axis falling when powered off, and remains released all the time the system is powered up and controlling the motors.

Thank you very much for your answer! I am not a native English speaker, sorry for the typing mess. The servo motor/driver does not have a brake, what the RAC and FAC clamp do is disable the ccw or cw in the driver respectively and they are normally connected to the sw limits, it is a safety mechanism that the driver has, if FAC and RAC are enabled (they are set to 15 volts) the motor can rotate in either direction if either is disabled the motor can only rotate in the opposite direction.
I have a "partial" solution I found the abs component and connect the 7i93 pwm output to the abs comp input and the output that says the sign of the analog signal to a 7i93 GPIO output that activates or deactivates the FAC/RAC I don't like it much but so far it is working. I don't know why I can't find the Dir signal of the 7i93 card it would be easier.

From your explanation, RAC and FAC seem to be Forward and Reverse limits on the drive, but i have never seen such letters on them.
First, you can ignore those, everything should work without those, but since they are there, they should be used and wired to the coresponding limit switches.
As for 7i93 dir signal, not sure why or how, but you can use any other output for dir signal, with some hal fiddling.
Do the drives have a dir pin?
You did mention ABS, and PWM, so that makes me think there is a missunderstanding somewhere.

In the photo you can see the driver with the FAC and RAC I cannot ignore them because otherwise the motor does not move. The servo driver works with +/- 10volt I have a 7i33 card for this purpose. I am referring to Pwm and Dir because according to the 7i33 manual it works that way to generate the +/-10volts. And as I said before the driver is not working well it has problems with the FAC and RAC signals the driver should work with both activated but it is not the case it only works when I activate a single clamp and it should not be like that, the other drivers are good and they work as they should.

OK, those were wired to the limit switches for sure, and should be wired back.
Sorry for being blunt, but you mentioned 7i93 twice, and you mentioned PWM and using ABS in hal, so that threw me off.
You do not need dir pins for +-10V controls, just wire back the RAC and FAC to the limit switches, they must be ON (connected to 15V) when limits are not triggered.

Thank you very much for your answer. I know that I don't need the pwm and dir pins to control the servo amplifier, the problem is that if I only connect FAC and RAC to the limit switches as it was originally, the motor will only move in one direction because the servo driver is bad. It only works if I activate one at a time, that's why I need the dir signal so that when it changes direction ccw or cw it tells me with a bit and I can use that signal to activate FAC and RAC as the case may be.
