(2) Cold-start level alarms
Code Error name Cause/Action
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-relay 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 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
“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 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 relay cable connecting the controller and simple
absolute unit to see if the connectors are loose. Or, replace the cable.
