Alarm group D: Controller-encoder abnormality alarm
An abnormality occurred between the controller and encoder.
No. Cause Countermeasure
1 If a similar alarm persists after turning the
power supply back on, it is likely that a contact
failure has occurred at the connector of the
cable that connects the controller and motor. After shutting off the power supply, remove the
cable connector and firmly re-insert it all the
way.
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 controller
and the motor may not match.
[Example]
An incremental encoder type motor and
battery-less absolute encoder spec controller
have been combined by mistake Cut off the power supply and make sure that
the specifications of the replaced motor and
controller are both "battery-less absolute
encoder specification" or "incremental encoder
specification".
→ For details, refer to " Controller
replacement (page 8-15 to 18)".
3 The communication between the controller 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 controller has failed. Replace the motor or controller cover assembly.
Customers may not replace the motor by
themselves. Contact IAI.

replacement (page 8-15 to 18)".
