[Alarm group D: ELECYLINDER control unit-encoder abnormality alarm]
An abnormality occurred between the ELECYLINDER control unit and encoder.
No. Cause Countermeasure
1 In case the alarm gets generated even after
rebooting the power, it could be concerned that
there is a contact error at a connector on the
cable between the ELECYLINDER control part
and the motor.
Shut the power down and take off the connectors
on the cable inside ELECYLINDER, and insert
again firmly till it stops.
If this does not improve the situation, the cable
may be disconnected, in which case the
connection cable should be replaced.
2 The specifications of the replaced
ELECYLINDER control unit and the motor may
not match.
[Example]
An incremental-type motor and battery-less
absolute spec ELECYLINDER control unit have
been combined by mistake
Cut off the power supply and make sure that the
specifications of the replaced motor and
ELECYLINDER control unit are both
"battery-less absolute specification" or
"incremental specification".
→
For the replacement method, refer to the
instruction manual for each ELECYLINDER.
3 The communication between the ELECYLINDER
control unit and encoder 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 protection, power line wiring,
electrostatic shielding, etc.) for the peripheral
device.
4 If this alarm recurs after performing the
inspection above and improving the power
supply environment, it is highly likely that the
motor or ELECYLINDER control unit has failed.
Replace the motor or ELECYLINDER controller
cover assembly. For some models, the motor
cannot be replaced by the customer. In that
case, please contact IAI.

For the replacement method, refer to the
instruction manual for each ELECYLINDER.
