Signals From Axis/Spindle (Db31 - Siemens SINUMERIK 840D sl Function Manual

DB31, ...
DBX3.1 Enable travel to fixed stop
Edge evaluation: no
Signal state 1 or Meaning when FXS function is selected using the part program
edge change (IS "Activate travel to fixed stop" = 1):
0 → 1
→ Travel to fixed stop is enabled and the axis traverses from the start position at the programmed
velocity to the programmed target position.
Signal state 0 Meaning when FXS function is selected using the part program
(IS "Activate travel to fixed stop" = 1):
→ Travel to fixed stop is inhibited.
→ The axis is stationary at the start position with reduced torque.
→ The channel message "wait": Auxiliary function acknowledgment missing" is displayed.
Edge change
1 → 0 Meaning before the fixed stop has been reached
(IS "fixed stop reached" = 0):
→ Travel to fixed stop is aborted.
→ The alarm "20094: Axis%1 Function aborted" is displayed.
Meaning after the fixed stop has been reached
IS "fixed stop reached" = 1):
→ The torque limiting and monitoring of the fixed stop monitoring window are canceled.

Edge evaluation: no
Signal state 1 or The "Travel to fixed stop" function is active.
edge change
This signal is used for analog drives in order, for example, to activate the current or torque limitation
0 → 1
parameterized in the actuator.
Signal state 0 or The "Travel to fixed stop function" is not active.
