Bit 0-2 JOG - Approaching fixed point 0/1/2
Edge evaluation: No
Signal state 1 or Activates the "approaching fixed point JOG" function.
edge change 0 → 1
The number of the fixed point to be approached is output through Bit 0-2 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 available fixed points (max. 4 for each axis) are defined via the following machine data:
MD30600 $MA_FIX_POINT_POS[n]
Signal state 0 or Deactivates the "approaching fixed point JOG" function.
edge change 1 → 0
