Alarm List
159
Alarm Code Alarm Name Cause/Treatment
90 Driver Board Mount
Error
Cause : The number of axes (number of driver boards) set in Gateway
Parameter Setting Tool does not match with the number of
the actually connected axes.
Treatment : Match the numbers of the axes.
9C Fieldbus Module Not
Detected
Cause : Communication board for field network was not detected.
1) Communication board is not inserted.
2) Malfunction of communication board
Treatment : Turn the power OFF and reboot. If the same error occurs
again, please contact IAI.
A0 Control Power
Overvoltage
Cause : Control power voltage reached beyond the overvoltage
threshold (120% of 24V DC = 28.8V).
1) The voltage of 24V DC power supply is high.
2) A faulty part inside the controller
3) Turning the servo ON at acceleration/deceleration spends
a huge current consumption 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 input power supply.
3) Think to use a power supply with enough current capacity
or not to use the remote sensing function.
If the voltage is normal, please contact IAI.
A1 Control Power Voltage
Drop
Cause : The control power voltage dropped less than the voltage drop
threshold (70% of 24V DC = 16.8V).
1) The voltage of 24V DC power is low
2) A faulty part inside the controller
Treatment : Check the power voltage.
If the voltage is normal, please contact IAI.
A2 Motor Power Voltage
Error
Cause : 1) Motor power input voltage (input to MPI terminal) is too
large (38V or more)
Turning the servo ON at acceleration/deceleration spends
a huge current consumption transiently. Using the remote
sensing function with a power supply with no enough
current capacity may cause overvoltage responding to the
current change.
2) Overcurrent is generated on the motor power supply line
Treatment : 1) Check the power voltage input to MPI terminal. Think to
use a power supply with enough current capacity or not to
use the remote sensing function.
2) Check the wire layout between the actuator and controller.
A6 Encoder Voltage Drop Cause : The power voltage for the encoder has dropped below the
allowable range.
Treatment : Check the connection between the actuator and Gateway
Unit.
AA Regenerative Electric
Discharge Circuit
Error
Cause : There is an error in the regenerative discharge circuit inside
the controller.
Treatment : Turn the power OFF and reboot. If the same error occurs
again, please contact IAI.
FF Power-on Log It is the log at the power being on (it is not an error).
