Cause Investigation and corrective actions
1
■
The data out of setting range was
given to system parameter.

servo amplifier. Check and correct
the setting value of system
parameter. Turn ON the control
power again and confirm that alarm
is cleared.
2
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
