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 output
torque, allowable moment of inertia,
acceleration/deceleration and speed, and
adjust them appropriately.
2
The power supply voltage has been detected
outside the range of 21.6 V to 26.4 V.
[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 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 10 m, 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
(page 8-15 to 18)".
