8.2 Servo System Troubleshooting
An AC servo system controls all servo axes in the machine. If there is a problem with
the servo system, the machine displays an alarm code to notify the operator.
This section describes alarm codes and inspection methods, and should be used as a
reference for troubleshooting and resolving problems.
8.2.1 Alarm Code Display
Each servo amplifier has an LED panel to display alarm codes.
The following illustrations show the location of each servo amplifier’s LED panel.
Note: To display the alarm code on the digital operator, connect the digital operator cable to the
servo amplifier (CN3 connector).
warning
The servo amplifier power terminal is high voltage.
Absolutely do not touch the servo amplifier power terminal.
