error
Cause : The data sent from the controller was not received properly
by the encoder side.
1) Encoder cable is partially disconnected, or connector is not
connected properly.
2) Influence from noise.
3) Failure of communication IC mounted on the encoder circuit
board.
4) Failure of communication IC mounted on the driver unit
circuit board.
Countermeasure : 1) Confirm that there is no failure in the cable and
connector coupler.
2) Try turning OFF power to all peripheral devices
and moving only the controller
error is generated, the culprit may be noise.
Take measures against noise.
3) or 4) is the case, replace the motor unit or
0E5
Encoder receipt error
Cause : This shows the data was not received in normal condition
from the encoder side to the controller.
1) Breakage of encoder cable or connection error on
connectors
(If the detail code in the alarm list of the teaching tool is
0002
H
.)
2) Effect of noise (Detail Code 0001
H
)
3) A faulty part inside the actuator (communication part).
4) A faulty part inside the controller (communication part).
5) Initialization of battery-less absolute encoder is incomplete
(Detail Code 000A
H
)
6) Error occurred in communication with battery-less absolute
encoder (Detail Code 000C
H
)
Countermeasure : 1) Check if any wire breakage on a connector and
the condition of wire connections.
2) Interrupt the power to the peripheral equipment
and activate only the actuator. If any error does
not occur, it might be caused by noise. Take
proper measures against noise.
3), 4) or 5) if it is the cause, is necessary to replace
the actuator (motor part) or controller.
6) Check a breakage of encoder cable and
connection on the connectors. For the high-
resolution battery-less absolute encoder, check
the capacity of 24V DC power supply and
connection on power supply wiring.
Cause : Error status was received in initial communication with
battery-less absolute encoder
Countermeasure : Reboot the power and conduct an absolute reset
(home-return operation).
Replace the motor unit in case the condition would
