1.3 Servo/Spindle Alarms
This section describes alarms occurred by the errors in the servo system such as the drive unit‚ motor and
encoder, etc. The alarm message‚ alarm No. and axis name will display on the alarm message screen. The
axis where the alarm occurred and the alarm No. will also display on the servo monitor screen and the
spindle monitor screen respectively. If several alarms have occurred‚ up to two errors per axis will display
on the servo monitor screen and the spindle monitor screen respectively.
(The bold characters are the messages displayed on the screen.)

Resetting methods
S01
PR
After removing the cause of the alarm, reset the
alarm by turning the NC power ON again.
S03
NR
After removing the cause of the alarm, reset the
alarm by inputting the NC RESET key.
S04
AR
After removing the cause of the alarm, reset the
alarm by turning the drive unit power ON again.
(Note 2) The resetting method may change according to the alarm class.
For example, even if “S03 SERVO ALARM: NR” is displayed, it may be necessary to turn the NC
power ON again.
