Automatic operation start (cycle start)

By specifying the program No., sequence No., and block No. of the G-code program for automatic operation, the specified
block is cued and a program can be started with the leading edge of "[Rq.3377] Automatic operation start (cycle start)
(D54226.1+2s)". An automatic operation holding and block stopping G-code program can also be restarted. Automatic
operation start is executed for each line.
G-code program priority
The level of priority for the specified program No., sequence No., and block No. is shown below.

G-code program start conditions
The conditions for operation of a G-code program specified by program No., sequence No., and block No. in "[Rq.3377]
Automatic operation start (cycle start) (D54226.1+2s)" are shown below.

(D54282+16s, D54283+16s)
 A minor error (error code: 1FC3H (details code: 031FH))
occurs.
No setting (=0) Starts from the start of the G-code program.
Set Starts from the position of the specified block of the blocks
from the start of the G-code program up until to the
sequence No. command.
No setting (=0) Starts from the position of the sequence No. specified by
the G-code program.
Set Starts from the position of the specified block of the blocks
from the sequence No. in the specified G-code program up
until the next sequence No. command.
Operation
[St.3214] Automatic
operation holding
(D54441.2+4s)
*1
OFF Starts the G-code program specified by program No.,
sequence No., and block No.
OFF Restarts the G-code program in the automatic operation
holding state.
ON Restarts the G-code program in the automatic operation
holding state.
OFF During automatic operating start, therefore the automatic
operation starting signal is ignored.
ON No such state exists.
