0CA Overheat Cause : This shows the heat on the
components inside the controller
inside the ERC3 motor unit is too high.
1) Operation is performed with the
load condition exceeding the
specified range.
2) High temperature around the
controller.
3) Load to the motor is high due to
external force.
4) Components’ failure of the controller
inside the ERC3 motor unit.
Treatment : 1) Revise the operation condition such
as decreasing the
acceleration/deceleration speed.
2) Lower the surrounding temperature
of the controller.
3) Confirm that there is no error in the
mechanical part assembly
condition.
(Note) This error would not normally occur. If it
occurs, confirm there is not (1) to (3)
above. If the same problem occurs again
even after taking these actions, it may be
concerned the malfunction of the controller
inside the ERC3 motor unit. Please contact
IAI.

Control power
source voltage
error
Cause : The control power voltage dropped
less than the voltage drop threshold
(120% of 24V DC = 28.8V).
1) The voltage of 24V DC power
supply is high.
2) Components’ malfunction of the
controller inside the ERC3 motor
unit
3) During acceleration/deceleration
and servo-on that use the remote
sensing function of 24V DC power
supply, the current consumption
rises transiently.
Using the remote sensing function
with a power supply with no enough
current capacity may cause
overvoltage responding to the
current change.
Treatment : 1) 2) Check the voltage of the power
supply.
3) Think to use a power supply with
enough current capacity or not to
use the remote sensing function.
In the case that the voltage is normal,
please contact IAI.
