Alarm
Code
Alarm Name
Cause/Treatment
A2
(8A2)
Overvoltage on motor
power
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
(8A6)
Encoder Voltage Drop
Cause
: The power voltage for the encoder has dropped below the
allowable range.
Treatment : Check the connection between the actuator and MCON.
AA
(8AA)
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.
AB
(8AB)
Assumed Regenerative
Discharge Excessive
Power
Cause
: The regenerative electric power exceeded what can be
dealt with the regenerative resistor.
Treatment : Decrease the acceleration/deceleration speed, revise the
operation interval or connect an external optional
regenerative resistor (RER-1).
AC
(8AC)
Continuous Regenerative
Excessive Discharge
Cause
: The regenerative electric power exceeded what can be
dealt with the regenerative resistor.
Treatment : Decrease the acceleration/deceleration speed, revise the
operation interval or connect an external optional
regenerative resistor (RER-1).
BA
(8BA)
Number of Axes /
Operation Mode
Unmatched
Cause
: The number of axes set in the gateway parameter and that
of axes figured out from the operation mode are not the
same.
Treatment : As the parameter setting is inappropriate, revise the
gateway parameter setting.
FA
(8FA)
CPU Error
Cause
: An error reset was detected in CPU in the gateway board.
Treatment : Turn the power OFF and reboot. If the same error occurs
again, please contact IAI.
FFF Power-on Log
It is the log at the power being on (it is not an error).
