Chapter 4: Enhanced Level Commands
(10)Supplements to Canned Cycle Functions
•
When a canned cycle is executed with the SINGLE-BLOCK switch set ON, the cycle
is suspended at the following points and the FEED HOLD lamp lights.
•
After positioning at (X, Y)
•
After positioning at R-point level
•
After the completion of one cycle if an L command is specified
•
Upon completion of a canned cycle, the single-block stop takes place as in operations
other than canned cycles and, in this case, the FEED HOLD lamp does not light.
•
Before entering the canned cycle mode, define the R-point and Z-point levels newly
by designating R and Z. The R-point and Z-point data is cleared when the canned
cycle mode is canceled.
•
If a canned cycle is executed after changing the address data, one of the following
address commands must be specified in that block; otherwise, the canned cycle is not
executed. X, Y, Z, a, b, R
•
When M, S, T, and/or B * is specified in a block which calls up a canned cycle, M, S,
T, and/or B * signal is output at the first positioning operation. If the number of repe-
titions (L) is specified, M, S, T, and/or B * signal is output at the first positioning oper-
ation, too. M, S, T, and B * commands should be specified in a block without other
commands.
•
If the following G codes are specified in the canned cycle mode, alarm “0170” occurs.
It is necessary to cancel the canned cycle mode before specifying these G codes.
G code in *-group with an exception of G04,G70,G71, and G72
•
G code in 07-group (G41, G42)
•
It is possible to insert the block that calls for dwell during the execution of a
canned cycle. In this case, dwell function is executed correctly.
•
If a canned cycle is called up in the tool radius offset C (G41, G42) mode, alarm “01
82” occurs.
•
Before entering a canned cycle, the spindle must have been started in automatic opera-
tion by executing M03 or M04. It is not allowed to enter a canned cycle after changing
the spindle rotation direction manually.
