(2) Cold Start Alarms
Code Error Cause/action
0A1 Parameter data error Cause: The parameter data does not meet the specified input range.
(Example) This alarm generates when a pair of values clearly has
an inappropriate magnitude relationship, such as when
the soft limit + setting is 200.3 mm, while the soft limit
– setting is 300 mm.
Action: Change the settings to appropriate values.
0A8 Unsupported
motor/encoder type
Cause: Motor type and/or encoder type set in parameters are not supported.
Action: Contact IAI if the error persists even after turning the power on
again.
0B4 Electric angle mismatch Cause: The position deviation counter has overflowed.
Action: Check if loads interfere with peripheral objects, the brake is released
or other load conditions exit.
Moreover, occurrence of deviation overflow (when phase-Z is
undetected) can be considered as a cause before the electric angle
is determined. In this case, disconnection of the motor cable and/or
output error of the encoder cable can be considered; check the
connection of the cables.
0B7 Indeterminable
magnetic pole
This controller detects the magnetic-pole phase when the servo is turned on
for the first time after turning on the power. This alarm indicates that the
magnetic-pole phase cannot be detected after a specified time.
Cause: [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] The load increased due to application of external force.
[4] The slide resistance of the actuator itself is high.
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 check if “click” sound is heard.
[3] Check the assembly condition of mechanical parts for any
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 itself is suspected as the cause, contact IAI.
0C8 Overcurrent Cause: The output current of the power-supply circuit became abnormally
high.
This alarm should not generate in normal conditions of use. If it
generates, the isolation of motor coil may have deteriorated.
Action: Measure the inter-phase resistances among motor connection wires
U, V and W, as well as the isolation resistance between the motor
connection wires and ground, to check for deterioration of isolation.
If you wish to measure the above resistances, contact IAI.
0CA Overheating Cause: [1] The temperature around the power transistor inside the
controller is too high (= 95 °C or higher).
[2] Lack of regeneration resistant energy because deceleration is
set too high at moving downward in case of vertically installed
controller.
[3] Default parts inside the controller
Action: [1] Lower the surrounding temperature of the controller.
[2] Review the setting conditions such that the deceleration speed
shows gradual curve.
If [1] or [2] is not the case, contact IAI.
