because I feel I wasn't very clear, I come back with more specifications:
After 3-days pause, my dmc103V - tnc426 doesn't start. When I switch-on, the monitor appears like in
the pictures attached, and doesn't go further (no references, and no unusual error display).
I mention that the error displayed up on the screen ("pneumatic switch signal 0") is normal at machine start (normally it will automatically cancel)
The problem is that the monitor does not display all. (in the first picture I marked the line where usually it should have been displayed the axis symbol x-y-z, and S - P.)
If I force to reference the axis, the alarm from second picture appears.
Thanks for suggestions
