DBX52.4-5 Plus or minus traversing request for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 A traversing request is available for the geometry axis for the corresponding traversing direction.
• Bit 4 = minus traversing request
• Bit 5 = plus traversing request
Operating modes:
• JOG mode:
Plus or minus traversing key
• REF mode:
Traversing key that initiates a traversing movement in the direction of the reference point.
• AUTOMATIC/MDI modes:
A program block with a traversing operation is executed for a geometry axis.
Signal state 0 There is no traversing request available for the geometry axis.

The output of the drive commands depends on:
MD17900 $MN_VDI_FUNCTION_MASK, bit 0
Bit 0 Meaning
0 The drive commands are already output when a traversing request is active.
Description
1 The drive commands are only output when the axis traverses.
Signal state 1 Request to traverse the geometry axis in the corresponding direction.
• Bit 6 = minus drive command
• Bit 7 = plus drive command
The response to a drive command depends on the current operating mode:
• JOG mode:
Traverse the axis in the traversing direction plus or minus.
• REF mode:
Traverse the axis only in the direction of the reference point.
• AUTOMATIC/MDI mode:
A block containing a position for the axis is executed.
Signal state 0 There is no traversing request available for the geometry axis.
