Code Error

name

Cause/Action

0A1 Parameter data error

Cause: The data input range in the parameter area is not appropriate.

(Example) This error occurs when the magnitude relationship is

apparently inappropriate such as when 300 mm was
incorrectly input as the value of the soft limit negative side
while the value of the soft limit positive side was 200.3mm.

Action: Change the value to an appropriate one.

0A8

Motor/encoder type not
supported

Cause:

The

monitor type or encoder type set in the applicable parameter is

not supported.

Action: If this error persists after reconnecting the power, contact IAI.

0B4

Electrical angle mismatch

Cause: The

position

deviation counter has overflowed.

Action:

Check

the load condition, such as whether the work is not contacting

any nearby object or if the break is released.
If the electrical angle is not yet confirmed (phase Z is not yet
detected), deviation overflow may be a cause. In this case, check
the cable connection because deviation overflow can be caused by
a broken motor wire or encoder line output error.

0B7 Indeterminate magnetic pole This controller will conduct magnetic pole phase detection when the servo is

first turned ON after the power is input. This alarm indicates that the magnetic
pole phase cannot be detected even with a lapse of a specified period of time.
Cause: [1] Loose or disconnected motor-relay cable connector

[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] 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

sound.

[3] Check the assembly condition of mechanical parts for abnormality.
[4] 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.

0C8 Overcurrent

Cause: The output current of the supply circuit has become excessively high.

This condition does not occur under normal operation, but insulation
degradation of the motor coil is suspected.

Action: Measure the phase resistance of the motor cable lines U, V and W and

insulating resistance with a ground to check the presence of insulation
degradation.
Before executing measurement, please contact IAI.

0CA Overheating

This alarm indicates that the temperature around the power transistor and
regenerative resistor in the controller is excessive.
Cause: [1] High temperature around the controller

[2] Excessive regenerative energy (The deceleration setting is too high

during a downward movement of the vertically installed actuator.)

[3] Faulty internal controller part

Action: [1] Lower the surrounding air temperature of the controller.

[2] Revise the settings so that the deceleration decrease.

If neither action [1] nor [2] improves the situation, contact IAI.
