Troubleshooting
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-type motor and battery-less absolute
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 specification" or
"incremental specification".
→For details, refer to "
Controller replacement
(page 8-15 to 16)".
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.
