8.1 Troubleshooting
In the following pages, explanations will be provided on the possible causes of each alarm and malfunction,
and of the investigative methods and corrective measures. To avoid injury, please ensure that the cause is
rectified and safety is ensured before attempting to resume operation in the event of an alarm or
malfunction.
It is highly dangerous to proceed with an investigation into the causes of a malfunction
without ensuring the safety of the servo amplifier, motors, mechanical devices and the
surrounding area. Understanding the conditions prevailing at the time of a malfunction will
help in narrowing down the possible causes of the malfunction and shorten the
troubleshooting process. Ensure that it is safe to do so before attempting to reenact the
malfunction, and pay close attention to the prevailing conditions during the reenactment.
In replacing Servo Amplifier and Servomotor, confirm that there should be no external
parameter causing any trouble to prevent dual breakage.
Please consult your Sanyo Denki dealer should the malfunction persist even after following
the troubleshooting procedures recommended in this guide.

blinking, and an alarm outputs from CN1. When an alarm occurs, execute the corrective measures
indicated for each alarm display in the following procedure.
1. See the consensus status in the "Operating State when Alarm
2. Execute the corrective measures in the "Corrective Measures"
