5-1 Points of caution and confirmation
If an error occurs in the spindle drive unit, the warning or alarm will occur. When a warning or alarm
occurs, check the state while observing the following points, and inspect or remedy the unit according
to the details given in this section.
<Point s of confirmation>
[1] What is the alarm code display?
[2] Can the error or trouble be repeated? (Check alarm history)
[3] Are the spindle motor and spindle drive unit temperature and ambient temperature normal?
[4] Are the power supply unit, spindle drive unit and motor grounded?
[5] Was the unit accelerating, decelerating or running at a set speed? What was the speed?
[6] Is there any difference during forward and backward run?
[7] Was there a momentary power failure?
[8] Did the trouble occur during a specific operation or command?
[9] At what frequency does the trouble occur?
[10] Is a load applied or removed?
[11] Has the drive unit been replaced, parts replaced or emergency measures taken?
[12] How many years has the unit been operating?
[13] Is the power supply voltage normal? Does the state change greatly according to the time band?
CAUTION
1. This power supply unit uses a large capacity electrolytic capacitor. When the
CHARGE lamp on the front of the power supply unit is lit, voltage is still
present at the PN terminal (TE2). Do not touch the terminal block in this
state.
2. Before replacing the unit, etc., always confirm that there is no voltage at the
PN terminal (TE2) with a tester or wait at least 15 minutes after turning the
main power OFF.
3. The conductivity in the unit cannot be checked.
4. Never carry out a megger test on the drive unit or power supply unit as the
unit could be damaged.
