LED Color and condition When illuminated, these LEDs indicate that the servo amplifier for the
corresponding axis has shut down and that a fault is present, such as:
• Motor or cable short circuit or open circuit
• Excessive DC input voltage to the amplifier
• Amplifier is overheated
• Power up reset
