Appendix 2 Explanation of Alarms
Alarm No. Sub side detector: Initial communication error
1A
Initial communication with the machine side detector failed.
Investigation details
Check the servo parameter
(SV025.pen:position detector) setting value.
Check the spindle parameter(SP019)
1
setting value.
Are the serial communication type detector
parameters set for the pulse type detector?
Check the detector.
2 Check if the pulse detector is used for the
detector specified to be serial.
Jiggle the detector connectors (drive unit
3 side and detector side) and check if they are
disconnected.
Turn the power OFF, and check the detector
4
cable connection with a tester.
Replace with another unit, and check
5 whether the fault is on the unit side or
detector side.
Check if there is any abnormality in the
detector's ambient environment.
6
(Ex. Ambient temperature, noise,
grounding)
Sub side detector: Error 1
Alarm No.
The machine side detector (CN3 side) detected an error. As details differ for each detector, refer to "Appendix 2.3.1" for
1B
the description of this alarm.
Investigation details
Check whether the servo axis has moved
1 and the spindle has rotated when an alarm
occurred.
Check whether the operation at low speed is
2
normal.
Jiggle the detector connectors (drive unit
3 side and detector side) and check if they are
disconnected.
Turn the power OFF, and check the detector
4
cable connection with a tester.
Replace with another unit, and check
5 whether the fault is on the unit side or
detector side.
Check if there is any abnormality in the
detector's ambient environment.
6
(Ex. Ambient temperature, noise,
grounding)
Sub side detector: Error 2
