E-Stop beim Starten von LinuxCNC immer AKTIV

QTplasmac has three different estop types that are defined in the ini.
Please consult the qtplasmac documentation

Ich verwende die AXIS-Benutzeroberfläche.
Ist es so, dass jede Maschine ohne diese Zeile immer im Not-Aus-Zustand ist?

I am using the AXIS user interface.
Is it the case that every machine without this line is always in the emergency stop state?
 

Yes, the estop is a loop.
That line is required but it can be different  with external hardware. In which case it is preferable (safer) to use estop-latch.
When I used a safety relay with an external estop button and an external estop latch button, the output from the safety relay was connected to  iocontrol.0.emc-enable-in

Actually re-reaading your first post, you have a safety relay. Here is mine.
 
The safety circuit is the red relay, the breaker above it and the two force guided relays below it (K3 & K4 in the diagram in the PDF)
A safety relay requires a pulse to latch the machine on (Eg take out of estop).
There are two ways to do this. 
One is to use an external momentary switch (which is what I did). In this case, I connected the latch button to an input. I simply did this in HAL
net emc-enable <= lcec.0.3.in-01
net emc-enable => iocontrol.0.emc-enable-in
Linuxcnc is enabled once the hardware latch button is pressed.

The other way to do this is to use 
iocontrol.0.user-request-enable
to enable the safety relay (S34 in my diagram)
iocontrol.0.user-request-enable receives a pulse you can see with halscope when the axis orange button is pressed which can be used in place of my eternal latch button. I did play with it this way and went with an external button. I think I just connected an output pin direct to S34.
 

Hallo Away
sorry

the E-Stop ( Not-Aus-Schalter) has normal NC contacts 
you really did NO contacts

ok danke thank´s
Away has drawn NO
and NC you can connect an infinite number of them in series
