2153 MCS CONAPA deviation
The difference between CON and APA has exceeded the permissible limit. CON-APA deviation is the absolute value of the difference between [calculated value written to MCS] and [actual position read from MCS].
NC control software detects this deviation, while normally the MCS detects the DIFF value.
This alarm occurs if a serious error occurs in the MCS and the DIFF value cannot be monitored.

2310 Unmanned Zero offset failure
MC937008R0700601940001
During execution of the zero offset cycle (OO20), there is no zero offset data.
If an auto gauging cycle has been executed before calling subprogram OO20, the results of the gauging cycle should have been set in system variables VS913, VS914, and VS915.
If the data in VS913, VS914, and VS915 is zero or blank, the control determines that the auto gauging cycle has not been performed and an alarm occurs.
Because control reset clears the contents of system variables VS913, VS914, and VS915, an alarm will still occur if CALL OO20 is executed after resetting the control.

Synchronization error (hexadecimal)
[Probable Faulty Locations]
Indicates that the mode for correcting synchronization errors has been established.
Operation example:
When bit 0 or bit 1 of optional parameter (bit) No. 37 is set to ”1″, the sync error correction mode or sync position shift amount setting mode is established.
[Measures to Take]
This alarm message only indicates the mode, and no special action is required. Cancel the designated mode and reset the control. The alarm will be cleared.

2430 Axis interlock
(1) A B-axis command was specified when the X-axis was not within 10 mm of the machine zero point.
(2) Or, in auto/MDI operation, an attempt was made to rotate the B-axis at a position other than the Z-axis retract position.
[Index]
None
[Character-string]
None
[Code]
6: On DCC-15/25/25Y, a B-axis command was issued without positioning the Y-axis at the machine zero point.
7: On DCC-15/25/25Y, Y-axis and B-axis commands were issued simultaneously.
8: A B-axis command was issued even though the X-axis was not positioned at its origin position No. 1.
9: A B-axis command was issued even though the Z-axis was not within 100 mm of its origin position No. 3.
A: The B-axis was commanded while pallet A was inside the machine.
11: During automatic or MDI operation, the Z-axis is outside the range between the upper and lower limits that permit B-axis rotation. Or, when the Z-axis command value was outside the limit range,
the B-axis was not at an angle permitting entry into the B-axis rotation prohibited range (machine coordinates).
12: An attempt was made to move the Z-axis with the pulse handle in a direction away from the Z-axis limit range for B-axis rotation when the Z-axis was outside the limit range. Or, an attempt was made to rotate the B-axis.
13: An attempt was made to move the Z-axis by manual rapid traverse or jog feed in a direction away from the Z-axis limit range for B-axis rotation when the Z-axis was outside the limit range. Or, an attempt was made to rotate the B-axis.
14: An attempt was made to index the B-axis when the Z-axis was outside the limit range for B-axis rotation.
15: An attempt was made to rotate the B-axis at a position other than the Z-axis retract position in auto/MDI operation.
[Measures to Take]
11: Position the B-axis at an angle permitting entry into the B-axis rotation prohibited range. Or, move the Z-axis into the range between the upper and lower limits for B-axis rotation.
12: Move the Z-axis into the range between the upper and lower limits for B-axis rotation.
13: Move the Z-axis into the range between the upper and lower limits for B-axis rotation.
14: Move the Z-axis into the range between the upper and lower limits for B-axis rotation.
15: Rotate the B-axis with the Z-axis at origin position No. 10.
Disable the B-axis rotation interlock function.
