Parameterisation
Required input parameters
| Input parameters | Description | 
| @P1 | Reference plane (absolute) | 
| @P2 | Retraction plane (absolute) | 
| @P3 | Safety clearance in Z (relative to reference plane/machining height) | 
| @P4 | Depth of longhole (relative to reference plane) | 
| @P5 | Maximum infeed Z (unsigned) | 
| @P44 | Number of longholes | 
| @P72 | Length of longhole | 
| @P74 | Circle radius of centre point positions | 
Optional input parameters
| Input parameters | Description | 
| @P20 | Feed rate for finishing for milling in the XY plane (values in mm/min, inch/min) | 
| @P21 | Feed rate for infeed in Z (values in mm/min, inch/min) | 
| @P32 | Feed mode in Z 1: Vertical 2: Oscillating (default) | 
| @P40 | Position of circle centre point in X Default value is the current position | 
| @P41 | Position of circle centre point in Y Default value is the current position | 
| @P45 | Starting angle of first slot (in degrees) Default value = 0 | 
| @P46 | Incremental angle (in degrees) Default value = 360°/number of longholes | 
The function of the parameters acting in the XY plane is derived largely from the graphic below:
It is recommended to use the Syntax check.to verify whether the input parameters are correctly assigned.

Parameters which mainly refer to the Z axis are displayed in the graphic below:
