such as the auxiliary function and dwell
functions are performed without movement
in the tool nose radius compensation
mode. Modify the program.
042 G45/G48 NOT ALLOWED IN
CRC
(M series)

turn command. Modify the program.
047 ILLEGAL AXIS SELECT Two or more parallel axes (in parallel with
a basic axis) have been specified upon
start–up of three–dimensional tool com-
pensation or three–dimensional coordi-
nate conversion. Modify the program.
048 BASIC 3 AXIS NOT FOUND Start–up of three–dimensional tool com-
pensation or three–dimensional coordi-
nate conversion has been attempted, but
the three basic axes used when Xp, Yp, or
Zp is omitted are not set in PRM1022.
049 ILLEGAL OPERATION
(G68/G69)
(M series)

coordinate conversion (G68, G69) and tool
length compensation (G43, G44, G45) are
not nested. Modify the program.
