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)
880
The direction of movement of the handwheel does not match the expected direction of the axis.
The handwheel is assigned to different axes with different orientations.
