input error and stop the running program

Hi,

I'm Romain, I live in France and I'm a newbie in Linux and Linux CNC.

I'm finishing to build my gantry CNC Machine (X 2800 mm, Y 1500 mm (gantry), Z 200mm). The X and Y are moved by racks and pinions and Z by ball screw. I use 4 x 130W servo motor with Heidenhain Rod 426 encoder for alls axis drived by 4 CNC drive DG2S. I tune the PID directly on the DG2S drives and I just configure Linux CNC like I used stepper motors.

When a drive detect an error, it stop alls the other drives and , It create a error input on the pin 10 of my parallel port.

I would like to stop the running program when this pin is high. I'm not very comfortable with HAL.

Could you help me to write this lines ?

Thanks for your help.

The axis.namp-fault-in will stop the exicution of a move or program, place the machine in power off, and gives an error message at the bottom of the screen.

Here is how I handled a fault signal from the drives on a machine:

---

net Xfault-in pcl720.0.pin-26-in => not.0.in
net Xfault not.0.out => axis.0.amp-fault-in

net Yfault-in pcl720.0.pin-24-in => not.1.in
net Yfault not.1.out => axis.1.amp-fault-in

net Zfault-in pcl720.0.pin-02-in => not.2.in
net Zfault not.2.out => axis.2.amp-fault-in

---

You would probably use somthing like this:

---

net Xfault-in parport.0.pin-10-in => axis.0.amp-fault-in

---

(assuming that this drive is connected to your first parallel port and the first or X axis)

Thanks guys, I'll probably test this tomorrow and I'll tell you if it will works.
