Three compensation centers can be specified by specifying their center
coordinates with parameters No. 5081 to 5086. The G41Pn (n = 1, 2, or
3) command is used to specify which compensation center is to be used.
G41 P1 ; Select the first compensation center. . . . . . .
G41 P2 Select the second compensation center. . . . . . .
G41 P3 ; Select the third compensation center.. . . . . .
When selecting the compensation center, specify P1, P2, or P3 at the same
time with G41. If G41 has been specified without a P command or with
a P command other than P1, P2, and P3, P/S alarm 5069 is issued.
When specifying the compensation center with parameters, use the
workpiece coordinates.
To enter compensation mode, specify the compensation center, then
specify a D code other than D0. A compensation vector is created and the
tool is accordingly moved, even if the block in which the D code has been
specified does not contain a move command.
