Notes on multiple repetitive cycle (G70- -G76)
1. G70, G71, G72, or G73 cannot be commanded in MDA mode. If it is comman-
ded, alarm 14011 is generated. However, G74, G75, and G76 can be comman-
ded in MDA mode.
2. M98 (subprogram call) and M99 (subprogram end) cannot be commanded in
the blocks in containg G70, G71, G72, or G73 and between the sequence num-
bers specified by addresses P and Q.
3. The following commands cannot be specified in the blocks between the se-
quence numbers specified by addresses P and Q:
-- One shot G codes with the exception of G04 (dwell)
-- 01 group G codes with the exception of G00, G01, G02, and G03
-- 06 group G codes
-- M98 / M99
4. Do not program in such a way that the final movement command of the contour
definition for G70, G71, G72, and G73 finishes off with chamfering or corner
rounding. An alarm is issued whenever the above is specified.
5. In the G74, G75, and G76 cycles, addresses P and Q use the least input incre-
ments to specify the amount of travel and depth of cut.
6. No tool nose radius compensation can be carried out within G71, G72, G73,
G74, G75, G76, or G78 cycles.
