List of Error Codes
Appendix D
Note (1) Errors that occur in the MECHATROLINK-II I/F Unit cannot be detected by the PCU because the
communications connection is not established. The PCU is not able to detect the corresponding axis
during execution of CONNECT, so an MLK Initialization Error (Unit error code: 0020 hex) will occur.
(2) This alarm occurs when using an R88D-WT
@
W-series Servo Drive together with the FNY-NS115
MECHATROLINK-II I/F Unit.
(3) This alarm occurs when using an R88D-WN
@
-ML2 W-series Servo Drive.
(4) This alarm may occur when a SMARTSTEP Junior Servo Drive (R7D-ZN
@
-ML2) is being used. The
A.28 (emergency stop) alarm is treated as an emergency stop signal input error (axis error code:
3004 (hex) in the Position Control Unit and the Servo will be unlocked for the axis.
(5) This alarm is not detected for SMARTSTEP Junior Servo Drives (R7D-ZN
@
-ML2).
List of W-series and SMARTSTEP Junior Warning Displays
Note (1) This warning is not detected for SMARTSTEP Junior Servo Drives (R7D-ZN
@
-ML2).
(2) If a Parameter Setting Warning or MECHATROLINK-II Command Warning occurs in the Servo
Drive, a data setting error (axis error code: 3099 hex) will occur at the PCU, and the active axis in
which the error occurred will decelerate to a stop.
(3) If a MECHATROLINK-II communications error occurs once independently, a communications warn-
ing occurs, and the PCU will perform a communications retry. If the communications warning occurs
continually, a communications error will occur.

4090 Deviation counter over-
flow The number of pulses in the deviation counter has exceeded the
deviation counter overflow level set in Pn505 (when using R88D-
WT
@
) or Pn520 (when using R88D-WN
@
-ML2) multiplied by the
rate (%) set in Pn51E.

4091 Overload or fluctuation This warning occurs before the Overload Alarm (A.71
@
, A.72
@
)
occurs. If operation is continued in this state, an alarm may
occur. This warning also occurs when an abnormal fluctuation is
detected in the Servomotor rotation speed.
A.92
@
(See
note 1.)
4092 Regeneration overload This warning occurs before the Regeneration Overload Alarm
(A.32) occurs. If operation is continued in this state, an alarm
may occur.
A.93
@
(See
note 1.)
4093 Battery warning
(Absolute encoders only) This warning occurs before the Battery Error (A.83) occurs. If the
power is turned OFF, an alarm may occur the next time the
power is turned ON. (Replace the battery while the control circuit
power supply is ON.)
A.94
@
See note 2. Parameter setting warn-
ing
A value outside the setting range has been set for the MECHA-
TROLINK slave station device.
A.95
@
See note 2. MECHATROLINK-II com-
mand warning
An illegal communications command or unsupported communi-
cations command has been sent to the MECHATROLINK slave
station device.
A.96
@
4096 Communications warning A single MECHATROLINK-II communications error has
occurred. (See note 3.)
