Troubleshooting
Alarm group E: Supply voltage/power capacity abnormality alarm
An abnormality occurred in the power supply voltage and capacity supplied
to the rear of the ELECYLINDER.
No. Cause Countermeasure
1 The ELECYLINDER may be being used under
conditions exceeding the specifications described in
the catalog. Check the specification values such as payload,
acceleration/deceleration and speed, and adjust
them appropriately.
2 The power supply voltage has been detected outside
the range of 21.6V to 26.4V. [Countermeasure 1]
Inspect with a tester to see whether the power supply
voltage is in the range of 21.6 V to 26.4 V.
If it is out of range, the 24VDC power supply voltage
has insufficient capacity.
Refer to our catalog for the required capacity and
improve the power supply environment.
[Countermeasure 2]
Check whether the length of the power I/O cable is
within 10m, and whether the wire diameter is smaller
than the applicable value.
Make sure the wiring processing is correct.
→For details, refer to "3.4/3.5 Wiring connections".
3 Overcurrent has occurred on the I/O output part. (1) Check if the current has exceeded the rated
output current on the I/O output part. Check if
there is a connectivity error to the host device.
(2) Check if there is a connectivity error to the host
device. Make sure it is established correctly and
then reboot the power.
4 If this alarm recurs after performing the inspection
above and improving the power supply environment,
it is highly likely that the controller has failed. Replace the controller cover assembly.
→ For details, refer to " Controller replacement
