DBX7.0 Invert handwheel direction of rotation (machine axes)
Application exam‐
● The direction of movement of the handwheel does not match the expected direction of the axis.
ple(s)
● The handwheel is assigned to different axes with different orientations.

Bit 0-2 JOG - approach fixed point
Edge evaluation: No
Signal state 1 Activates the "approaching fixed point JOG" function.
The number of the fixed point to be approached is specified in bits 0-2 in binary code.
The selected machine axis can be traversed to the corresponding fixed point with the traverse keys
or the handwheel as soon as the function is active (see DB31, ... DBX75.0-2).
The fixed points are defined using the following machine data:
MD30600 $MA_FIX_POINT_POS[n]
Signal state 0 Deactivates the "approaching fixed point JOG" function.
Corresponding to ... DB31, ... DBX75.0-2 (JOG - Approach fixed point)
DB31, ... DBX75.3-5 (JOG - Approach fixed point)
MD30600 $MA_FIX_POINT_POS[n] (fixed value positions of the axis)

Signals from axis/spindle (DB31, ...)

Description of signals from axis/spindle
DB31, ...
DBX62.1 Handwheel override active
Edge evaluation: no
Signal state 1 or edge The function "Handwheel override in AUTOMATIC mode" is active for the programmed positioning
change 0 → 1 axis (FDA[AXi]). Handwheel pulses for this axis affect the programmed axis feedrate either as path
definition (FDA=0) or as velocity override (FDA > 0).
The interface signal will also be set if "Handwheel override in automatic mode" is active with a con‐
current positioning axis with FC18 ( for 840D sl).
Signal state 0 or edge The function "Handwheel override in AUTOMATIC mode" is not active for the programmed position‐
change 1 → 0 ing axis (or concurrent positioning axis).
An active handwheel override is not active if:
● the positioning axis has reached the target position
● the distance-to-go is deleted by axis-specific interface signal
● a RESET is performed.
