R parameters

R parameters (arithmetic parameters) are channel-specific variables that you can use within a G
code program. G code programs can read and write R parameters.
These values are retained after the controller is switched off.
Comments
You can save comments in the "R parameters with comments" window.
These comments can be edited. You have the option of either individually deleting these
comments, or using the delete function.
These comments are retained after the control is switched off.
Number of channel-specific R parameters
The number of channel-specific R parameters is defined in a machine data element.
Range: R0-R999 (dependent on machine data).
There are no gaps in the numbering within the range.
