7.3 Causes and countermeasures for ELECYLINDER alarms
7-8
ME0394-1A
[Alarm group B: Motor abnormality alarm]
Motor abnormality occurred.
No. Cause Countermeasure
1 The internal temperature of the motor may be
too high.
Improve the surrounding environment of the
motor so that the ambient temperature is 40 °C
or less.
If the abnormality is resolved upon turning the
power back on after the ambient temperature is
lowered, the internal temperature may have
been excessive.
[Countermeasure examples]
Remove the heat source/turn OFF the heat
source/install a fan/install a temperature
shield/improve thermal conductivity of the
base/install a heat dissipation fin, etc.
2 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.
3 If this alarm recurs after performing the
inspection above and improving the power
supply environment, it is highly likely that the
motor has failed.
Replacement of the motor is required. For some
models, the motor cannot be replaced by the
customer. In that case, please contact IAI.
[Alarm group C: ELECYLINDER control unit abnormality alarm]
ELECYLINDER control unit abnormality occurred.
No. Cause Countermeasure
1 The ELECYLINDER control unit is affected by
the noise of a peripheral device and cannot
operate normally.
Shut down the power supply of the peripheral
device and operate only with the
ELECYLINDER, then check to see whether this
alarm persists.
If it does not, there is a possibility that the
ELECYLINDER is affected by the noise from the
peripheral device.
Reconsider the noise countermeasures
(grounding, power line wiring, electrostatic
shielding, etc.) for the peripheral device.
2 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.
