6-2-1 List of alarms
When an alarm occurs, the servo drive unit will make the motor stop by the deceleration control or
dynamic brake. The spindle drive unit will coast to a stop or will decelerate to a stop. At the same time,
the alarm No. will appear on the NC monitor screen and with the LEDs on the front of the drive unit.
Check the alarm No., and remove the cause of the ala rm by followin g this list.
