Alarm Code | Message | Description |
---|---|---|
749 | S–SPINDLE LSI ERROR | It is serial communication error while system is executing after power supply on. Following reasons can be considered. 1) Optical cable connection is fault or cable is not connected or cable is cut. 2) MAIN CPU board or option 2 board is fault. 3) Spindle amp. printed board is fault. If this alarm occurs when CNC power supply is turned on or when this alarm can not be cleared even if CNC is reset, turn off the power supply also turn off the power supply in spindle side. |
750 | SPINDLE SERIAL LINK START FAULT | This 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. The four reasons can be considered as follows: 1) An improperly connected optic cable, or the spindle control unit’s power is OFF. 2) When the NC power was turned on under alarm conditions other than SU–01 or AL–24 which are shown on the LED display of the spindle control unit. In this case, turn the spindle amplifier power off once and perform startup again. 3) Other reasons (improper combination of hardware) This alarm does not occur after the system including the spindle control unit is activated. 4) The second spindle (when SP2, bit 4 of parameter No. 3701, is 1) is in one of the above conditions 1) to 3). See diagnostic display No. 409 for details. |
751 | FIRST SPINDLE ALARM DETECTION (AL–XX) | This alarm indicates in the NC that an alarm is generated in the spindle unit of the system with the serial spindle. The alarm is displayed in form AL–XX (XX is a number). Refer to 2.3 or 2.4 Alarms displayed on spindle servo unit .The alarm number XX is the number indicated on the spindle amplifier. The CNC holds this number and displays on the screen. |
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. |
761 | SECOND SPINDLE ALARM DETECTION (AL–XX) | Refer to alarm No. 751. (For 2nd spindle) |
762 | SECOND SPINDLE MODE CHANGE FAULT | Refer to alarm No. 752.(For 2nd spindle) |
764 | SPINDLE–2 ABNORMAL TORQUE ALM | Same as alarm No. 754 (for the 2nd spindle) |
771 | SPINDLE–3 ALARM DETECT (AL–XX) | Same as alarm No. 751 (for the 3rd spindle) |
772 | SPINDLE–3 MODE CHANGE EROR | Same as alarm No. 752 (for the 3rd spindle) |
774 | SPINDLE–3 ABNORMAL TORQUE ALM | Same as alarm No. 754 (for the 3rd spindle) |
