2.6 Travel to fixed stop (F1)
2.6.1 Signals to axis/spindle (DB31, ...)
DB31, ...
DBX1.1 Acknowledge fixed stop reached
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Significance after the fixed stop has been reached:
DB31, ... DBX62.5 (fixed stop reached) = 1
→ The axis presses against the fixed stop with the clamping torque:
→ The fixed stop monitoring window is activated.
→ A block change is executed.
Signal state 0
Edge change
1 → 0
Significance after the fixed stop has been reached:
DB31, ... DBX62.5 (fixed stop reached) = 1
→ The axis presses against the fixed stop with the clamping torque.
→ The fixed stop monitoring window is activated.
→ A block change is not executed and the channel message
"Wait: Auxiliary function acknowledgment missing" is displayed.
Meaning after the fixed stop has been reached:
IS "Fixed stop reached" DB31, ... DBX62.5 = 1
→ The function is aborted, the alarm "20094 axis %1 Function aborted" is output.
Significance when de-selecting the function FXS=0 via the part program:
→ The torque limiting and the monitoring of the fixed stop monitoring window are canceled.

DBX1.2 Sensor for fixed stop
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Fixed stop is reached.
Signal state 0 or
edge change
1 → 0
Fixed stop is not reached.
Corresponding to .... The signal is only active if:
MD37040 $MA_FIXED_STOP_BY_SENSOR = 1
