3.1.9 G29 — Z Reference Point Return
Command format ： G29 ;
After X returns to the reference point with G27 at the rapidest traverse speed controlled by the
rapid traverse override, Z offsets of tool and system are cancelled. When X offset value is also 0,
and the tool offset number is displayed to 0.
Note:
The cautions of G27, G29 are the same those of G26.
3.1.10 G31 —Skip
Command format
：
G31 X
（
U
）
_ Z
（
W
）
_ F_
；
X , Z — end point coordinates after the command ends.
U, W — incremental value counted by the theory end point.
F — feedrate.
Command function: execute G31 according to G01 run mode, and check the outer skip signal in
running. In spite of arriving or exceeding the theory end point, the run stops and
the current coordinates are changed to the theory values counted by X, Z or U,
W values in programs when the outer signal is valid.
Example
：
current coordinates X=100 Z=100
G31 Z30 F20
；
The moving distance is Z70, Z runs with 20mm/min, no matter what it exceeds Z30, Z
always runs without the outer signal; when Z=28.37 and the outer signal is valid, Z
immediately stops and the current Z coordinate is changed to 30.
Note: G31 input interface: X4.14.
Attention: to get the accurate position, the run stops immediately and there is no deceleration course
once the system has checked the outer signal. So, the run speed in G31 cannot be high,
and it is recommended that it is should be less than the value of P21.
3.1.11 G04 — Dwell
Command format
：
G04 D ;
D—dwell time. Unit: second range
：
0.001
－
65.535s
G04 defines the meantime between two blocks.
Example
：
G04 D2.5
；
dwell for 2.5s.
3.1.12 Constant Surface Speed ON/OFF—G96/ G97
Command format ： G96 S ;
G97 S;
S defines the constant surface speed in G96. Unit
：
m/min.
S defines the spindle speed in G97 after canceling the constant surface speed. Unit
：
r/min.
Note 1:
The spindle speed is controlled actually by the constant surface speed control function
when the system adopts the spindle controlled by the converter, i.e. MDSP=1 of P12.
