Detailed Description
2.6 Travel to fixed stop (F1)
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 Meaning before the fixed stop has been reached
1 → 0 (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.
