I Programming
(2) Positioning to the 2nd reference position set by data parameter No.1241 at the setting speed by
data parameter No.31 (from point B to point R2)
(3) When the reference point returns if the machine is unlocked, the Bit 0 and Bit 1 of the reference
point returning end signal F96(ZPn) are HIGH.
Note 1: After returning the machine reference point by manual or the G28 command is performed, the machine 2nd,
3rd and 4th reference point return function can be employed only, or the 2nd, 3rd and 4th reference point
operation of G30 command , the system alarm will be generated.
Note 2: From point A to B or from point B to R2, the 2 axes are moved at their separately rate, so the path is not
straight line possibly.
Note 3: After machine 2nd, 3rd and 4th reference point returned by the G30 command, the system tool length
compensation cancellation is defined by bit 7 of the parameter No.13
Note 4: The 2nd, 3rd and 4th reference point operation of G30 command can not be executed if the zero switch is not
installed on the machine tool.
Note 5: The workpiece coordinate system is set after the machine 2nd, 3rd and 4th reference point are returned.
3.14 Skip Function G31
As G01 linear interpolation is performed, if an external SKIP signal is valid during execution of this
command, execution of this command is interrupted and the next block is executed. The skip function is
used when the end of machining is not programmed but specified with a signal from the machine, for
example, in grinding. It is used also for measuring the dimensions of a workpiece.
Format
:
G31 X__ Y__ Z__
Explanation
:
1. G31, which is a non-modal G-code, it is effective only in the block in which it is specified.
2. G31 can not be specified in the tool compensation C and chamfering, or the alarm will be
generated. It is very necessary to cancel the tool compensation C and chamfering
firstly before the G31 command is specified.
3. Error is allowed in the position of the tool when a skip signal is input.
Signal
:
The SKIP signal input is on the fixed address X1.0 (CN61-42).

SKIP
1: HIGH level SKIP is valid;
0: LOW level SKIP is valid.
G31P
1: G31 is for immediate stop as the SKIP signal is valid;
0: G31 is for decelerating stop as the SKIP signal is valid.
1. The next block to G31 is incremental command 1
: it moves with incremental value
