13) Spindle alarms
Number Message Contents
749 S–SPINDLE LSI ERROR A communication error occurred for the serial spindle. The cause
may be the disconnection of an cable or the interruption of the power
to the spindle amplifier.
(Note) Unlike spindle alarm No. 750, this alarm occurs when a serial
communication alarm is detected after the spindle amplifier is
normally activated.
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) Defective cable, poor connection, or spindle amplifier being
switched 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.
See diagnostic display No. 409 for details.
