Plus and minus traversing request for orientation axis (1, 2, 3)
Signal state 0 A traversing command in the relevant axis direction has not been given or a traversing movement
has been completed.
• JOG mode:
The traversing command is reset depending on the current setting "JOG or Continuous mode"
(see DBX12.7 or DBX12.6 ff.
While traversing with the handwheel.
• REF mode:
When the reference point is reached.
• AUTOMATIC/MDI mode:
The program block has been executed (and the next block does not contain any coordinate
values for the axis in question).
Cancel by "RESET", etc.

Traversing command plus and minus for orientation axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
The interface signal behaves differently depending on following machine data setting:
• MD17900 $MN_VDI_FUNCTION_MASK, bit 0 == 0
Behavior corresponding to the following description:
• MD17900 $MN_VDI_FUNCTION_MASK, bit 0 == 1
Signal state 1: Only if the geometry axis actually traverses.
The interface signal
DB21, ... DBX 332, 336, 340 Bit 5, 4 (traversing request plus/minus)
which is always output, has the same effect as signal traversing command plus/minus with MD17900, bit 0 = 0.
Signal state 1 A traverse movement of the axis is to be executed in one or the other direction. Depending on the
mode selected, the command is triggered in different ways:
• JOG mode:
With the plus or minus traversing key.
• REF mode:
With the traversing key that takes the axis to the reference point.
• AUTOMATIC/MDI mode:
A program block containing a coordinate value for the axis in question is executed.
