2711 Door open
Spindle rotation was commanded during VAC motor operation preparation while machine door was open.
Normally, if spindle rotation is commanded during VAC motor operation preparation, Alarm D 4213
"VAC motor not ready" will occur. Spindle rotates after the operation ready signal turns ON.
However, the above operation with the machine door open is extremely dangerous as it causes sudden spindle rotation.
Therefore, this alarm occurs to prohibit spindle rotation even if machine door interlock is OFF.
When machine door interlock is ON, Alarm A 1304 "Machine door interlock" occurs.
[Target]Spindle, M-tool spindle

2712 ATC specification not provided

Check whether ATC-related commands are correct.

2714 ATC TC
TC command specified a non-existent turret number.
TC/Turret indexing command at ATC position: TC = ## (## indicates turret number).
[Target]System
[Code]Hexadecimal number.
[Probable Fault Cause]
Program error
Program example:
:
TC=5
:
[Measures to Take]
Check TC command. (1<=TC<=4)
:
TC=3
:

2716 ATC TL
TL command value is abnormal.
TL command indexed a tool pot with no tool mounted. During restart function sequence recovery,
TL command attempted to index a tool pot with no tool mounted.
TL/Tool number indexing command: TL = &&$$%% (&& indicates tool nose radius compensation number, $$ indicates tool number,
%% indicates tool offset number.)
[Code]XXYYZZ
XX: Tool nose radius/tool diameter compensation number.
YY: Tool number.
ZZ: Tool offset number.
[Measures to Take]
During sequence restart recovery, ensure that the tool mounted on the turret matches the tool specified in the program.

2717 ATC MT

6->M06 command was issued during a tool calling or storing
movement.
7->M228 command was issued during a tool calling or storing
movement.
[Probable Fault Cause]
1) For LB35II-MATC-Y and LU45-MATC-Y, the next tool state corresponds to ATC operation
sequence Nos. 12 and 49; for LB15II-MATC-Y, the next tool preparation state corresponds to ATC
operation sequence Nos. 8 and 51. The M06 command was executed when the ATC operation sequence number was not in the next tool preparation state.
2) For LB35II-MATC-Y and LU45-MATC-Y, the tool return operation start state corresponds to
ATC operation sequence Nos. 27 and 68.
For LB15II-MATC-Y, the tool return operation start state corresponds to ATC operation sequence Nos.
23 and 65. The M228 command was executed when the ATC operation sequence number was not in the tool return operation start state.
3) M06 command was executed when the turret was not at the tool change position.
5) For LB15II/LB35II-MATC-Y and LU45-MATC-Y, the MG command can only be executed at sequence Nos.

[Code]
1->Group 1 request command and group 2 request command were executed simultaneously.

2723 ATC cannot prepare next tool
When executing the MT command, the ATC operation sequence number is not 1. The MT-commanded tool does not exist in the magazine.
Or, the MT-commanded tool is not ready at the standby station.
The MT-commanded tool cannot be mounted on the turret.
Or, ATC macro command M421 was executed before the MT command was completed.
1->MT command was issued during a tool calling or storing
movement.

2724 ATC sub-arm position incorrect
When pulling or inserting a tool with the sub-arm, the sub-arm is not at the standby station or magazine position.
[Code]
1->When pulling a tool with the sub-arm, the position is unknown.
2->When inserting a tool with the sub-arm, the position is unknown.
[Probable Fault Cause]
1) Sub-arm standby station position input (I/O check input No. 65 bit 4 iSARS).
2) Sub-arm magazine position input (I/O check input No. 65 bit 5 iSAMG).
Program example:
TN=28, M228
Operation example:
The cycle start button was pressed during tool extraction or insertion with the sub-arm in select or step operation.
[Countermeasures]
Check the ATC input bits on the check data screen.

2725 RS tool L/M type mismatch
The tool type (L/M) prepared at the standby station does not match the turret at the ATC position.
(T1 -> L tool, T3 -> M tool)
[Probable Fault Cause]
The programmed tool and the tool type in the magazine do not match.
[Countermeasures]
Correct the program or exchange the tool type in the magazine.

2726 Magazine encoder read
An error occurred when reading the magazine position encoder.
[Code]
1->Magazine

2727 Magazine rotation condition
At the magazine rotation command, the magazine is not in a condition where rotation is permitted.
[Code] XX
9->The sub-arm is not at the magazine rotation enable position.
10->The lock pin at the magazine manual tool loading position is not at the clamp position.
11->For tool ID specification, the tool ID data read arm is not at the retract position.
12->The pot is not unclamped.
13->The pot is not at the front change position.
14->The ATC arm is not at the EAMG position.
17->For tool ID specification, the tool attachment is
not in data read position (left position).
[Probable Fault Cause]
9) For LB35II-MATC-Y and LU45-MATC-Y, the sub-arm position permitting magazine rotation is
when the sub-arm is at the RS position or facing the RS direction. Otherwise, the magazine cannot rotate.
10), 11) Magazine rotation is prohibited when the lock pin at the magazine manual tool loading position is not at the clamp position, or the tool
ID data read arm is not at the retract position.
12), 13), 14) For LB15II-MATC-Y, magazine rotation is permitted only when the pot is unclamped and at the front change position,
and the ATC arm is at the EMAG position.

2728 Magazine tool No. mismatch
The input signal status of the tool presence check proximity switch at the magazine ATC position
does not match the data set on the ”*ATC MAGAZINE INFORMATION*” screen in tool data setting.
[Object] System
[Code] X
1->Tool data is present on the ”*ATC MAGAZINE INFORMATION*” screen, but the magazine tool presence check proximity switch is OFF.
2->Tool data is not present on the ”*ATC MAGAZINE INFORMATION*” screen, but the magazine tool presence check proximity switch is ON
.
[Probable Fault Cause]
Whether a tool is mounted in each pot is set and displayed on the “*ATC MAGAZINE INFORMATION*” screen. For the pot indexed
to the magazine ATC position, the presence or absence of tool data on the ”*ATC MAGAZINE INFORMATION*” screen
should match the input signal of the magazine tool presence check proximity switch.
However, this alarm occurs when a mismatch between the tool data setting and the input signal is caused by an incorrect data setting on the ”*ATC MAGAZINE INFORMATION*” screen, a faulty proximity switch, or a disconnected signal cable.

2729 No return pot in magazine
There is no empty pot in the magazine when returning a tool to the magazine.
[Probable Fault Cause]
There is no empty pot in the magazine. Incorrect tool data is set on the ”*ATC MAGAZINE INFORMATION*” screen in tool data setting.
When setting tool diameters, note that large-diameter tools require two consecutive empty pots, and extra-
large-diameter tools require three consecutive empty pots. An empty pot refers to a pot whose tool No. is 0 on the
”ATC MAGAZINE INFORMATION” screen. Also note that dummy pots do not represent empty pots.
When the magazine is of fixed pot specification, there is no spare
pot in the magazine.

2730 Cannot insert tool
A tool is present in the pot at the tool change position, and the tool cannot be retracted into the pot.
[Code]
1->Tool cannot be returned to the magazine.
2->Tool cannot be returned to the turret.
[Probable Fault Cause]
Operation error
Operation example: The tool No. write button was pressed.
[Countermeasures]
Prepare a pot for the return tool.
When returning an extra-large tool, three consecutive empty pot positions are required.
When returning a large tool, two consecutive empty pot positions are required.
