Caution
While a warning is detected, the normal operation can be
held. However, if the condition is going on, the alarm may
occur. Review the operational condition before alarm
occurrence.
A warning is not latched at the time of detection. Without
warning, it is automatically released.

7.9.1.2. Troubleshooting in case of Alarm Occurrence
When an alarm occurs, take the corrective measures according to each alarm display in
the following procedure.
2. T
Caution
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 to specify roughly those 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 conditions causing any trouble in order
to prevent double faults.
Please consult your Sanyo Denki dealer should the
malfunction persist even after following the troubleshooting
procedures recommended in this guide. As for where to
make contact, refer to the back cover of this manual.
1. See the consensus status in the “Operating State when Alarm
Occurred” and find the “High” in the possible cause number.
ake the corrective measures in the “Corrective Measures”
corresponding to the number above (with “High”).
3. If the malfunction persists after the above process, take the
corrective measures of number with “Low”.
4. If the malfunction still persists after No.3 above, consult with us.
