* In the alarm code list, description of P6PC shows RCM-P6PC, P6AC shows RCM-P6AC and P6DC shows RCM-P6DC.
Alarm
Code
Alarm
Level
Alarm Name Cause/Treatment
0D4 Drive Source error Cause : Overcurrent is generated on the motor power
supply line.
Treatment : Check the wire layout between the actuator and
controller.
0D5
For
RCP6S
and
P6PC
only
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.
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.
0D9 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.
0DC
Operation
release
Pressing motion range
over error
Cause : 1) After the pressing operation has complete, the
force to push back is too large and the pushed
back to the pressing start position (“Position” in
the position table).
2) The actuator touched the work during the
approach movement before the pressing
movement.
Treatment : 1) Revise the setting and adjust it so the force to
push back gets smaller.
2) Set the “Position” setting in front in the position
table to shorten the approach distance.
0DE
For
P6AC
and
P6DC
only
Cold start
External output power
source error
Cause : Error in external power supply to brake-release, LS
and so on.
Treatment : Reboot the power. Please contact us if the problem
is not solved with this action.
0DF
For
RCP6S
and
P6PC
only
Operation
release
Collision detection Cause : Collision of actuator was detected.
Treatment : Remove the cause of collision.
If it is an unexpected detection, re-adjust the
collision detection feature.
