[Rq.3376] G-code control request (D54226.0+2s)
This signal starts G-code control on a line by turning ON "[Rq.3376] G-code control request (D54226.0+2s)" of the applicable
line. Turning OFF "[Rq.3376] G-code control request (D54226.0+2s)" when "[St.3208] During G-code control (D54440.0+4s)"
is ON, ends G-code control. Refer to G-code control system start/end for details.(Page 25 G-Code Control System Start/

[Rq.3377] Automatic operation start (cycle start) (D54226.1+2s)
• This command is used for starting G-code program start, restarting after automatic operation hold, and restarting a block
stop.
• "[St.3213] Automatic operation starting (D54441.1+4s)" is turned ON with the leading edge (OFFON) of "[Rq.3377]
Automatic operation start (cycle start) (D54226.1+2s)" until "[Rq.3378] Automatic operation hold (feed hold)
(D54226.2+2s)" turns ON, or the block is stopped with "[Rq.3379] Single block (D54226.3+2s)" turned ON.
• In the following cases, "[Rq.3377] Automatic operation start (cycle start) (D54226.1+2s)" is disabled even when turned ON.
• When "[St.3213] Automatic operation starting (D54441.1+4s)" is already ON.
• When "[Rq.3378] Automatic operation hold (feed hold) (D54226.2+2s)" is ON.
• When "[St.3216] Resetting (D54441.8+4s)" is ON.
• When an error is occurring.
• In the following cases, automatic operation hold or stop, and block stop occurs.
• When "[Rq.3378] Automatic operation hold (feed hold) (D54226.2+2s)" is turned OFFON.
• When "[Rq.3380] Reset command (D54226.4+2s)" was turned ON.
• When no longer in program operation mode.
• When the block being executed ends after "[Rq.3379] Single block (D54226.3+2s)" has turned ON.
[Rq.3378] Automatic operation hold (feed hold) (D54226.2+2s)
• This command is used for performing a deceleration stop while moving by automatic operation.
• After turning OFF "[Rq.3378] Automatic operation hold (feed hold) (D54226.2+2s)", the command restarts at the leading
edge (OFFON) of "[Rq.3377] Automatic operation start (cycle start) (D54226.1+2s)". If "[Rq.3377] Automatic operation
start (cycle start) (D54226.1+2s)" is turned ON when "[Rq.3378] Automatic operation hold (feed hold) (D54226.2+2s)" is
ON, a minor error (error code: 1FC2H (details code: 0202H)) occurs.
• When "[St.3213] Automatic operation starting (D54441.1+4s)" is turned ON by the leading edge (OFFON) of "[Rq.3378]
Automatic operation hold (feed hold) (D54226.2+2s)", automatic operation hold occurs and "[St.3214] Automatic operation
holding (D54441.2+4s)" turns ON.
[Rq.3379] Single block (D54226.3+2s)
• This command is used for executing the G-code programs of automatic operation one block at a time.
• When automatic operation is being executed, it stops after the block being executed ends. To execute commands for the
next block, turn ON "[Rq.3377] Automatic operation start (cycle start) (D54226.1+2s)" again.
• Operation stops after one block. Therefore it is possible to execute a G-code program one block at a time.
