Alarms, Causes and Actions

(1) Operation Cancellation Alarms

Code Error

Cause/action

0A2

Position data error

Cause: [1] A move command was input when a target position was not yet

set in the “Position” field.

[2] The target position in the “Position” field is outside the soft limit

range.

[3] A target position was specified as a relative coordinate in the

“Position” field in solenoid valve mode 0.

Action: [1] Set a target position first.

[2] Change the target position to a value inside the soft limit range.
[3] Specify the target position as an absolute coordinate.

0A3 Position

command

information data error

Cause: The speed or acceleration/deceleration at the value command

exceeded the maximum setting value.

Action: Change to the appropriate value.

0B5

Phase-Z position error

The position at which the phase-Z was detected at homing was outside the
specified range.
Cause: Encoder error
Action: Contact IAI.

0BA

Home sensor not yet
detected

This alarm indicates that the actuator equipped with a home check sensor did
not complete homing successfully.
Cause: [1] The load contacted peripheral equipment during the homing.

[2] The slide resistance of the actuator is large in some areas.
[3] The home check sensor is not installed properly, or the sensor

is faulty or its circuit is open.

Action: If the load is not contacting any peripheral equipment, [2] and [3] are

suspected. Contact IAI.

0BE

Homing timeout

Cause: After the start of homing, homing does not complete after elapse of

the time set by the manufacturer’s parameter. (This alarm does not
generate during normal operation.)

Action: As one possible cause, the controller and actuator combination may

be incorrect. Contact IAI.

0C0

Excessive actual speed Cause: The motor speed exceeds the maximum speed set by the

manufacturer’s parameter.
This alarm does not generate during normal operation, but it may
occur if the load decreased before a servo error was detected and
the motor speed has increased as a result. This condition occurs
due to the following reasons:
[1] The slide resistance of the actuator is large in some areas.
[2] The load increased due to momentary application of external

force.

Action: Check the assembly condition of mechanical parts for any

abnormality. If the actuator itself is suspected as the cause, contact
IAI.

0C9 Excessive

motor

power-supply voltage

This alarm indicates that the voltage of the motor power supply is excessive
(24 V + 20%: 28.8 V or above).
Cause: [1] The voltage of the 24-V input power supply is high.

[2] Faulty part in the controller

Action: Check the input power-supply voltage.

If the voltage is normal, contact IAI.
