If R and W do not have same sign and |R| > |W|, 0792-G90, G92, G94 program error alarms,
and the value of R exceeds allowed range
4) During first tool cutting, if W is 0, current value is the end coordinates by default; U can’t be 0, or
else the system alarms
5) Before executing G94, specify the position of start point, or else the system takes current point as
the start
6) G94 is valid in MDI mode, and modal function is also available.
3.5.4. Notice for fixed cycle instructions
1) In the fixed cycle instruction, once X(U), Z(W) and R are executed, the instruction values
of X(U), Z(W) and R are always valid before new fixed cycle instruction to re-specify
X(U), Z(W) and R. If G00, G01, G02, G03 and G32 are executed, the values of X(U),
Z(W) and R will be cleared;
2) If the next block of G90, G92 or G94 is instruction word without motion, the action of
G90, G92 or G94 block will be executed again when the block without motion is
executed. To avoid this instance, it is required to cancel the cycle action with other G
instructions after the fixed cycle instruction;
(For example)
M3; (turn on the principal axis)
…
G90 X200.0 Z10.0 F2000;
X205.0 (repeat G90 once)
