As shown in the figure, “IF [# 1000 EQ1] GOT
O # 1033 ".

The above “IF” is a “conditional branch”,
In the system variable “# 1000”, information on whether or not “resume” is stored. As a result, if the stored value of the system variable “# 1000” is “0”, “restart” does not have to be performed, and if “1”, the “restart” is performed.
Subsequently, a “resume sequence number” is stored in the system variable “# 1033”.

Therefore, when the value of the system variable of “# 1000” is “1”, the “GOTO” command causes
The “resume sequence No.” stored in the system variable “# 1033” is read. Step 17 above
In (S17), when the storage value of the system variable of “# 1000” is “0”, that is, when it is not necessary to perform “restart”, as shown in FIG.

"0" means a "nail skipping" command, and the actual nailing operation of the nail 1000 is not performed.

Note that the last block “X □□□.
□□ Y □□□. The coordinate position of “□□” indicates a dummy point. That is, step 21 shown in FIG.
The return to the reference point in (S21) is usually performed at a low speed. On the other hand, the feed speed of each block is set to a high speed.

For this reason, by setting the dummy point at a coordinate position close to the reference point, it is possible to shorten the time required to return to the reference point. Thereby, the nailing operation of the nailing machine 100 can be speeded up. The above-mentioned “T0” is inserted not only in the last block but also between other blocks, and when the XY table 300 is moved to the coordinate position of the next block, the nail 1
It can also be used to prevent interference between the 000 and the nail holding device 700.
