Alarm
Code
Alarm
Level
Alarm Name Cause/Treatment
0D4 Drive source error Cause : 1) Motor power input voltage (input to MPI
terminal) is too large
During acceleration/deceleration and servo-on,
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.
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.
Please report the environment of use and
condition of operation in case this error occurs
often.
0D5
Only for

drivers
Cold start
Differential Counter
Overflow with Home
Return Incomplete
Cause : This alarm indicates that the position deviation
counter has overflowed.
1) The speed dropped or stopped during JOG
move due to an impact of external force, hit to
the mechanical end or overload.
2) The excited-phase detection operation following
the power-on is unstable.
Treatment : 1) This error occurs when the actuator cannot be
operated as it is commanded. Check the load
conditions such as if the work is touching to the
surrounding object, or brake is properly
released, and remove the cause.
2) Overload is concerned. Revise the transportable
weight.
0D8 Deviation overflow Cause : This alarm indicates that the position deviation
counter has overflowed.
1) The speed dropped or the actuator stopped due
to the effect of external force or overload.
2) The excited-phase detection operation following
the power-on is unstable.
3) The power supply voltage dropped.
4) Servo gain number is too small
Treatment : 1) This error occurs when the actuator cannot be
operated as it is commanded. Check the load
conditions such as if the work is touching to the
surrounding object, or brake is properly
released, and remove the cause.
2) Overload can be concerned. Revise the
transportable weight and redo the home-return
operation.
3) Check for the source voltage.
4) Tune the servo-motor gain number.

Software stroke limit
exceeded
Cause : The current position of the actuator exceeds the
software stroke limit.
Treatment : Return the actuator to be within the range of the
software stroke limit.
