Status at the time of alarm
Cause
1 2 3 4 5
Issued when control power is turned ON.
✔ ✔
Issued when main circuit power supply is
turned ON.
✔ ✔ ✔
Issued during operation. ✔ ✔
Cause Investigation and corrective actions
1
■
Input power supply voltage is below
the specified range.
■
Check the power supply and set it
within the specified range.
2
■
Rectifier of main circuit is broken.
■
Replace the servo amplifier.
3
■
Input power supply voltage is
reduced, or instantaneous power
interruption is occurred.
■
Check the power supply, and
confirm that there is no
instantaneous power interruption or
low voltage.
4
■
Low voltage outside of the specified
range is supplied to the main circuit
(R/S/T).
■
Check the main circuit voltage.
Confirm that there is no external
power supply to R/S/T when the
main circuit is OFF.
5
■
Defect in internal circuit of servo
amplifier.
