7.3 Causes and countermeasures for ELECYLINDER alarms
7-10
ME0394-1A
[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]
Confirm that the length of the power supply I/O
cable is 10m or less or the diameter is not thinner
than the appropriate.
Confirm that the wiring layout is appropriate.
3 If this alarm recurs after performing the
inspection above and improving the power
supply environment, it is highly likely that the
ELECYLINDER control unit has failed.
Replace the controller cover assembly.
→ For the replacement method, refer to the
instruction manual for each ELECYLINDER.
