Code Error name Cause/Action
0B8 Excitation detection error This control performs excited phase detection when the servo is turned
ON for the first time after the power has been input. When this error
generates, it means that the specified encoder signal level could not be
detected after 100 ms of excitation.
[1] The connector of the motor relay cable is loose or its circuit is
open.
[2] If the actuator is equipped with a brake, the brake cannot be
released.
[3] Large motor load due to application of external force
[4] The power was input when the actuator was contacting the
mechanical end.
[5] Large slide resistance of the actuator itself
Action: [1] Check the wiring condition of the motor relay cable.
[2] Check the wiring condition of the brake cable, and also turn on/off
the brake release switch to see if the brake makes a “clicking”
sound.
[3] Check the assembly condition of mechanical parts for
abnormality.
[4] Move the actuator away from the mechanical end and then
reconnect the power.
[5] If the load weight is normal, cut off the power and move the
actuator by hand to check the slide resistance.
If the actuator is suspected to be the cause, please contact IAI.
0E5 Encoder receive error Cause: [1] When the 24-V power supply is turned on, the controller power
turns on before the power to the simple absolute unit.
[2] When the detailed code is H’0001:
The controller cannot communicate with the simple absolute unit
properly due to noise, etc.
[3] When the detailed code is H’0002:
The controller cannot communicate with the simple absolute
unit properly due to a broken communication wire in the
encoder cable, etc.
Action: [1] Make sure the power to the simple absolute unit turns on
before (or at the same time as) the controller power.
[2] Change the installation location of the controller. Install a FG,
noise filter, clamp filter or implement other noise elimination
measure.
[3] Check the connectors on the encoder relay cable between the
controller and simple absolute unit for looseness. Or, replace
the cable.
0E8 Phase-A/B disconnection
detection
0E9 Phase-A disconnection
detection
0EA Phase-B disconnection
detection
Encoder signals cannot be detected correctly.
Cause: [1] Loose or disconnected encoder-relay cable connector
[2] Loose or disconnected actuator-end connector of the supplied
cable
[3] When a high-thrust rod-type actuator or actuator is used in
combination with other types of actuators, the encoder relay
cables are combined wrongly.
Action: Check the connection condition of the encoder relay cable and
conduct a continuity check. If the results are normal, please
contact IAI.
If [3] is the case, check the model of each encoder relay cable and
connect the correct cable to each actuator without making wrong
combinations.
Cable model for high-thrust rod-type actuator: CB-RFA-PA***
Cable model for other types of actuators: CB-RCP2-PA***
