We have two brand new Argon drives in our Linuxcnc machine.
Step and dir signals of J5 are used for motions.
STO1 and STO2 signals of J2 port on first drive are connected to the emergency circuit of the machine.
Enable input signal on first drive is connected to the safety door to prevent motions while the door is open.
Drives are connected together with RJ45- cable.
Problem is that randomly either drive does not go to enable-state even when Enable input signal is present.
