The AppDep form
Positions and variants of the approach and departure movements are
defined in this form.
Approach: Influence the approach strategy.
Departure: Influence the departure strategy (also applies for Y-axis
functions).
"Approach" parameters
APP
Type of approach:
 No axis (switch off the approach function)
 0: Simultaneous (X and Z axes approach diagonally)
 1: First X, then Z
 2: First Z, then X
 3: Only X
 4: Only Z
XS, ZS Approach position: Position of the tool point before cycle
call
Additionally with C-axis operations:
CS
Approach position: C-axis position that is approached
before cycle call with G110.
"Approach with Y axis" parameters
APP
Type of approach:
 No axis (switch off the approach function)
 0: Simultaneous (X and Z axes approach diagonally)
 1: First X, then Z
 2: First Z, then X
 3: Only X
 4: Only Z
 5: Y direction only
 6: Simultaneous with Y (X, Y and Z axes approach
diagonally)
XS, YS,
ZS Approach position: Position of the tool point before cycle
call
CS Approach position: C-axis position that is approached
before cycle call with G110.
"Departure" parameters
DEP
Type of departure:
 No axis (switch off the departure function)
 0: Simultaneous (X and Z axes depart diagonally)
 1: First X, then Z
 2: First Z, then X
 3: Only X
 4: Only Z
XE, ZE Departure position: Position of the tool point before the
movement to the tool change point.
