YASKAWA MOTIONPACK-110 Descriptive Information page 84

NOTE
1. Q, I, J, If are modal during combined operation command modes and
are effective until the combined operation command is cancelled. Specify
them without signs.
2. Variable pitch can also be programmed by symbol Q instead of I.
Furthermore, when instructions Q, I, J, K are given simultaneously,
drilling cycle is executed with variable drilling pitch with Q as
the initial value.
Q0 must be commanded in the block including modal G code before
programming variable pitch with I, J, and K.
(Program Example)
G91 G83 X... Y... T-30. Z-5500 I1000 J100 K400 F...;
Drilling pitch
1st plunge .-- 10 mm <= I1000
2nd plunge .-- 9 mm
3rd plunge ..- 8 mm
4th plunge ... 7 mm
5th plunge ... 6 mm
6th plunge ... 5 mm ¢= K400
7th plunge .." 4 mm
8th plunge ... 4 mm
9th plunge ... 2 mm ¢= K'
Total 55.00 mm ¢= Z-5500
(b) When the combined operations are executed by turning on the SINGLE BLOCK switch,
a temporary stop is made in an intermediate position, and the temporary stop lamp
lights up.
(1) After positioning to (X, Y) point
(2) After positioning to R point
(3) After termination of each cycle, if L command has been given.
The single block stop after the completion of combined operation is normal, and
the FEED HOLD lamp does not light up.
(c) Be sure to designate the R point and Z point by programming R and Z before entering
the combined operation command mode. R point and Z point are cleared when
combined operation commands are cancelled.
(d) When executing combined operation commands with the symbol data changed, the
block requires any of the following symbol commands. The combined operation will not
be executed otherwise.
X,Y,Z
