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 It was detected that the power voltage on 24 V
DC went out of the range between 21.6 and
26.4 V.
[Countermeasure 1]
Use a tester to check if the power the power
voltage on 24 V DC is in the range between
21.6 and 26.4 V.
If it is out of range, the 24 V DC 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 8-17 to 21 and 22)".
