List of Error Codes
Appendix D
Example: Position deviation overflow alarm (deviation counter overflow)
Servo Drive alarm display: A.24
The PCU's error code in this example is 4018.
Example: Battery warning
Servo Drive warning display: A.92
The PCU's error code in this example is 4092.
For details on alarm display and warning display numbers, and the difference between Servo Drives and Posi-
tion Control Units, refer to the list in Appendix D List of Error Codes.
W-series and SMARTSTEP Junior Servo Drives
Error code: 40

hex
The boxes (

) indicate the alarm/warning display number for the Servo Drive.
When using an R88D-WN
@
-ML2 W-series Servo Drive with built-in MECHATROLINK-II communications, how-
ever, only the upper two digits of the display number's three digits will be displayed.
The alarms that occur in the Servo Drive correspond to error codes that are detected by the PCU when a
MECHATROLINK communications connection has been established, as shown in the following table.
When using an R88D-WT
@
Servo Drive, the two digits following “A.” in the Servo Drive’s display number in the
table are displayed. When using an R88D-WN
@
-ML2 W-series Servo Drive, three digits are displayed (the
value indicated by the display number box is used to further classify the alarm).
For details on each alarm and countermeasures, refer to the operation manual for the Servo Drive being used.
List of G5-series Alarm Displays
The Servo Drive has built-in protective functions. When a protective function is activated, the Servo Drive turns
OFF the alarm output signal (ALM) and switches to the Servo OFF status.
The alarm code will be displayed on the front panel.
Alarm type
Description
---
Protective function that allows the alarm to be reset, and leaves record in the alarm history.
PR
Protective function that does not allow the alarm to be reset, and requires the control power supply
to be turned OFF and turned ON again after resolving the problem.
X
Protective function that does not leave record in the alarm history.
