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.

2.1 Alarm Code Display

Each servo amp has an LED panel to display alarm codes.

The following illustrations show the location of each servo amplifier’s LED panel.

WARNING

The servo amplifier power terminal is high voltage.

Absolutely do not touch the servo amplifier power

terminal.

Note: To display the alarm code on the digital operator, connect the digital operator cable to the

servo amplifier (CN3 connector).
