List of Error Codes
Appendix D
(2) When multiple warnings occur, the warning codes are displayed on the front panel in the order of
their priority (shown above). The value read from the network is set.
List of G-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.

Error detection function Detected error or cause of error
A.11 400B X Control power supply und-
ervoltage The DC voltage of the main circuit has dropped below the
specified value.
A.12 400C --- Overvoltage The DC voltage of the main circuit is abnormally high.
A.13 400D X Main power supply under-
voltage The DC voltage of the main circuit is low.
A.14 400E PR Overcurrent Overcurrent flowed to the IGBT. Servomotor power line
ground fault or short circuit.
A.15 400F PR Servo Drive overheat The temperature of the Servo Drive radiator exceeded the
specified value.
A.16 4010 --- Overload Operation was performed with torque significantly exceeding
the rating for several seconds to several tens of seconds.
A.18 4012 PR Regeneration overload The regenerative energy exceeded the processing capacity
of the regeneration resistor.
A.21 4015 PR Encoder communications
error Communications between the encoder and the Servo Drive
failed for a specified number of times, thereby activating the
error detection function.
A.23 4017 PR Encoder communications
data error Communications error occurred for the data from the
encoder.
A.24 4018 --- Deviation counter overflow The number of position deviation pulses exceeded the Devi-
ation Counter Overflow Level (Pn209).
A.26 401A --- Overspeed The rotation speed of the Servomotor exceeded the setting
of the Overspeed Detection Level Setting (Pn073).
A.27 401B PR Command error The operation command resulted in an error.
A.29 401D --- Internal deviation counter
overflow The value of the internal deviation counter (internal control
unit) exceeded 2
27
(134217728).
A.34 4022 --- Overrun limit error The Servomotor exceeded the allowable operating range set
in the Overrun Limit Setting (Pn026) with respect to the posi-
tion command input.
A.36 4024 PR
X
Parameter error Data in the parameter save area was corrupted when the
data was read from the EEPROM at power-ON.
A.37 4025 PR
X
Parameter corruption The EEPROM write verification data was corrupted when
the data was read from the EEPROM at power-ON.
A.38 4026 X Drive prohibit input error Forward and Reverse Drive Prohibit Inputs (NOT and POT)
both became OPEN.
A.40 4028 PR Absolute encoder system
down error The voltage supplied to the absolute encoder dropped below
the specified value.
A.41 4029 PR Absolute encoder counter
overflow error The multi-turn counter of the absolute encoder exceeded
the specified value.
