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 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
(page 8-20)".
