0A1
Parameter data error
Cause:
The input range of parameter range data is not appropriate.
(Example) This error occurs when the magnitude relationship of a pair
of range parameters is inappropriate, such as when the
value of soft limit- is mistakenly set to 300 mm when the
value of soft limit+ is 200.3 mm.
Action: Change the parameters to appropriate values.
0A8
Unsupported
motor/encoder type
Cause:
The motor type or encoder type set in the parameter is not supported.
Action: If the error persist after reconnecting the power, contact IAI.
0B8
Pole sense error
This controller performs excited-phase detection when the servo is turned on for
the first time after the power on. This error indicates that the specified encoder
signal level could not be detected after excitation for the time set by parameter
No. 29 (Excited-phase signal detection time).
Cause: [1] Loose or disconnected motor-extension cable connector
[2] Brake cannot be released on a controller equipped with brake.
[3] Large motor load due to application of external force
[4] Power was input when the actuator was contacting a mechanical
end.
[5] Large slide resistance of the actuator itself
Action: [1] Check the wiring condition of the motor extension 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 “click” sounds.
[3] Check for abnormality in the assembly condition of mechanical
parts.
[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 reception
error
Cause:
[1] The controller was powered up before the simple absolute unit when the 24-
V power supply was turned on.
[2] When the detail code is H’ 0001
The controller cannot communicate with the simple absolute unit properly
due to noise, etc.
[3] When the detail code is H’ 0002
The controller cannot communicate with the simple absolute unit properly
due to encoder cable disconnection, etc.
Action:
[1] Make sure the simple absolute unit is powered up before the controller (or
at least the two are powered up simultaneously).
[2] Change the installation location of the controller. Provide noise elimination
measures such as setting a frame ground, noise filter or clamp filter.
[3] Check the encoder extension cable connecting the controller and simple
absolute unit to see if the connectors are loose. Or, replace the cable.
