Excitation detection error
Cause: When excitation detection was performed in the first servo ON
process after power ON, excitation detection operation did not
complete after a given period of time.
1) Connection failure or disconnection of the actuator
connecting cable.
2) The brake cannot be released (for models with brake).
3) The load on the motor is large due to external force.
4) The power was turned ON while in contact with the
mechanical end.
5) The sliding resistance of the actuator is excessive.
Countermeasure: 1)
Check the wiring status of the actuator connecting cable.
2) If there is no problem with the 24 VDC power
supplied to the control power connector of the
gateway unit, the RCON system may be faulty.
Contact IAI.
3) Confirm that there are no assembly errors in
machine components.
4)
Move the slider or the rod tip to a point where it will
not hit the mechanical end and reboot the power.
5) If the load weight is within the specifications, turn
OFF the power supply and manually check the

of exceeding torque
allowing continuous
pressing
Cause: The continuous pressing time exceeds the time set for
parameter No.89 “Allowable time of exceeding torque allowing
continuous pressing”.
Countermeasure: Check the sequence again.
Set the pressing time to be within the setting time.
0C8 Overcurrent Cause:
The output current of the power supply circuit was abnormally high.
Countermeasure: This does not normally occur. There may be
insulation deterioration of the motor coil, RCON
system failure, etc. Contact IAI.

Driver
Cause: The power regenerative circuit voltage reached the judgment
value or higher.
Countermeasure: There may be an RCON system failure. Contact IAI.
