0BE Home return
timeout
Cause : Home return does not complete after
elapse of a certain period after the
start of home return.
Treatment : This error does not occur in normal
operation. Please contact IAI.
{ { { {
0C0 Actual speed
excessive
Cause : This indicates the number of motor
rotation exceeded the number of
allowable rotation.
1) The slide resistance of the actuator
is locally high.
2) The load is increased too much due
to a external force.
With the reasons above, it can be
considered a sudden speed
increase has occurred before
detecting the servo error.
Treatment : Even though this would not occur in
normal operation, check if there is any
abnormality in the parts assembly
condition. Also check if there is a
possibility that an external force may
be applied in the direction of the
actuator movement.

Oper

e
Servo error Cause : It indicates 2 seconds has passed
without making a move since a move
command was received.
1) Connection error or wire breakage
of motor/encoder cables.
2) Brake is not released (when
equipped with a brake).
3) Load to the motor is high due to
external force.
4) The resistance in the actuator
sliding operation is large.
Treatment : 1) Check for the motor/encoder cable
wiring condition.
2) For Positioner Mode 1 and MEC
Mode 1, if the problem is solved
with 24V DC 150mA being supplied
to BK, it may be concerned a
malfunction of the controller inside
the ERC3 motor unit.
3) Confirm that there is no error in the
mechanical part assembly
condition.
4) If the loaded weight is within the
allowable range, turn the power off
and check the resistance in sliding
operation by moving the slider with
hand.
{ { { {
0C8 Overcurrent Cause : The output current in the power circuit
section is increased abnormally.
Treatment : This alarm will not be generated in
normal operation. There may be
concerned a degradation of motor
winding insulation, malfunction of the
controller inside the ERC3 motor unit,
etc. Please contact IAI.

Overvoltage Cause : The power voltage reached the
overvoltage.
Treatment : There may be concerned a
malfunction of a component of the
controller inside the ERC3 motor unit.
Please contact IAI.
