Serial Spindle Alarms
| Alarm Code | Type | Description of Alarm/Error |
| 749 | S-SPINDLE LSI ERROR | It is serial communication error while system is executing after power supply on. |
| 750 | SPINDLE SERIAL LINK START FAULT | The alarm is generated when the spindle control unit is not ready for starting correctly when the power is turned on in the system with the serial spindle. |
| 752 | FIRST SPINDLE MODE CHANGE FAULT | This alarm is generated if the system does not properly terminate a mode change. The modes include the Cs contouring , spindle positioning, rigid tapping, and spindle control modes. The alarm is activated if the spindle control unit does not respond correctly to the mode change command issued by the NC. |
| 754 | SPINDLE 1 ABNORMAL TORQUE ALM | Abnormal first spindle motor load has been detected. |
| 762 | SECOND SPINDLE MODE CHANGE FAULT | Refer to alarm No 752 for 2nd axis. |
| 764 | SPINDLE 2 ABNORMAL TORQUE ALM | Same as alarm No 754 for the second spindle. |
| 772 | SPINDLE 3 MODE CHANGE ERROR | Same as alarm No 752 for the third spindle |
| 774 | SPINDLE 3 ABNORMAL TORQUE ALM | Same as alarm No 754 for the third spindle |
| 782 | SPINDLE 4 MODE CHANGE ERROR | Same as alarm number 752 for the fourth spindle |
| 784 | SPINDLE 4 ABNORMAL TORQUE ALM | Same as alarm number 754 for the fourth spindle. |
