08430000
1-rotation Counter
Error
The encoder detected a
one-rotation counter error.
• There is excessive noise
• Failure due to vibration,
impact, condensation, for-
eign matter, etc.
√
08440000
Overspeed Error
The encoder detected the
overspeed.
• The motor was rotated by
external forces
• Encoder failure and false
detection
√
08450000
Encoder Memory
Error
The encoder detected a
non-volatile memory error.
• False detection due to a
data read error that was
caused by excessive noise
• Non-volatile memory failure
• Encoder failure
√
08460000
Absolute Position
Detection Error
The encoder detected a
multi-rotation counter error.
• A detection error was
detected in the multi-rota-
tion detection section of the
encoder
• There is excessive noise
√
08480000
Main Power Supply
Undervoltage (insuf-
ficient voltage
between P and N)
The main circuit power sup-
ply voltage fell below the
operation guarantee range
during Servo ON.
• Incorrect wiring of the main
circuit power supply
• The low power supply volt-
age is applied to the Servo
Drive
• The long time was set in
Momentary Hold Time and
the voltage was decreased
momentarily
• Servo Drive failure
√
08490000
Overcurrent Error
The current flowing to the
motor exceeded the protec-
tion level.
• There is a short-circuit,
ground fault, or contact fail-
ure on the U, V, or W motor
cable
• There is a short-circuit on
the wiring of External
Regeneration Resistor
• The insulation resistance
failed between the U, V, or
W motor cable and the
motor ground wire
• False detection due to the
noise
• Servo Drive failure
√
084A0000
Encoder Communi-
cations Disconnec-
tion Error
The communications dis-
connection was detected
between the encoder and
the Servo Drive.
• Noise into the encoder
cable
• Contact failure of the signal
line, and disconnection of
the encoder
• Power supply undervoltage
to the encoder
• Encoder failure
