relevant alarm number for the tapping feed axis is displayed.

Number Meaning Contents and remedy
408 SPINDLE SERIAL LINK START FAULT
This alarm is generated when the spindle con- trol unit is not ready for starting correctly when the power is turned on in the system with the se- rial 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 dis- play of the spindle control unit. In this case, turn the spindle amplifier pow- er 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 acti- vated.
409 SPINDLE ALARM DETECTION
A spindle amplifier alarm occurred in a system with a serial spindle. The alarm is indicated as ”AL–XX” (where XX is a number) on the display of the spindle amplifier. For details, see Section 14. Setting bit 7 of parameter No. 0397 causes the spindle amplifier alarm number to appear on the screen.
