DBX16.7 Delete S value
Edge evaluation: yes Signal(s) updated: cyclic
Edge change
0 → 1
Control mode:
• Spindle stops
• Program continues to run
• Spindle continues to run with the following S value, if M3 or M4 were active
Oscillation mode, axis mode, positioning mode:
• Signal has no effect for the corresponding function. However, if the open-loop control mode is
selected again, a new S value must be programmed.
Signal state 0 or
edge change
1 → 0
No effect.
Application
example(s)
Terminating traversing motion on account of an external signal (e.g. sensing probe).

DBX17.4 - DBX17.5
Re-synchronize spindle when positioning 2 and 1
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 When positioning, the spindle must be re-synchronized.
Signal state 0 or
edge change
1 → 0
No effect.
Signal irrelevant for
...
... spindle modes other than the positioning mode.
Application
example(s)
The spindle has an indirect measuring system and slippage may occur between the motor and the
clamp. If the signal=1 - when positioning is started, the old reference is deleted and the zero mark is
searched for again before the end position is approached.

DBX17.6 Invert M3/M4
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The direction of rotation of the spindle motor changes for the following functions:
• M3
• M4
• M5
• SPOS/M19/SPOSA from the motion; not effective for SPOS/M19/SPOSA from zero speed
(stationary).
Application
example(s)
The machine has a selector switch to changeover between a vertical and a horizontal spindle. The
mechanical design is implemented so that for the horizontal spindle, one more gearwheel is
engaged than for the vertical spindle. The direction of rotation must therefore be changed for the
vertical spindle if the spindle is always to rotate clockwise with M3.
