4.2.16 COMBINED OPERATION COMMANDS (G80 to G99) (Cont'd)
(e) When M, S or T code is given in the combined operation command, M, S, T signals are
sent at the first positioning in the block. In general, M, S, T should be commanded in
their own block.
(f) An input error is triggered when any one of the following G codes is programmed in the
combined operation command mode.
G codes of' group except for G04
When programming G92, G28 etc., make sure to cancel the combined operation
command in advance.
(g) During the combined operation command mode, only a dwell block (G04) can be
inserted. Correct dwell will be served.
(h) Start of spindle forward or reverse (M03 or M04) should be executed by automatic
operation commands before entering combined operations. Do not enter into combined
operations after manually switching the spindle between forward and reverse.
(i) Execution of subprogram (M98) in combined operation command mode. In a combined •
operation command mode, M98P... L...; can be programmed to call up subprogram
and the combined operation is continued in the subprogram. The address P (program
No. of the first block of subprogram) with M98 command destroys temporary the
contents of address P for designation of dwell time, but after the jumping to
subprogram, it resumes the contents.
• Programming consideration of M98 in the combined operation command mode
is the same as those of other than combined operation command modes. (e.g.
Restriction of execution to no more than four levels.)
(j) Changing of R point and Z point
When R is commanded instead of Z during the execution of combined operation in GPl
mode, Z becomes incremental value from the new R point. Care should be taken.
