-1 Error List
084B0000 Encoder Communi-
cations Error Illegal data was received
from the encoder the speci-
fied number of times. • Noise into the encoder
cable
• Contact failure of the signal
line, and disconnection of
the encoder
• Power supply undervoltage
to the encoder
√
P. A-129
084D0000 Non-volatile Memory
Hardware Error An error occurred on the
non-volatile memory. • False detection due to a
data read error that was
caused by excessive noise
• Non-volatile memory failure
√
P. A-130
18230000 Absolute Encoder
Multi-rotation
Counter Error The encoder detected a
multi-rotation counter error. • A temporary error occurred
in the encoder multi-rotation
detection function due to
vibration, impact, or con-
densation
• Encoder failure
√ P. A-130
18380000 System Error A hardware error due to the
self-diagnosis and a fatal
software error were
detected. • False detection due to a
data read error that was
caused by excessive noise
• A fatal software error was
detected
• Hardware failure
√ P. A-131
183A0000 Non-volatile Memory
Data Error An error of data saved in the
non-volatile memory was
detected. • Power interruption or noise
occurred while parameters
other than the safety were
saved
• Power interruption or noise
occurred while the motor
identity information was
saved
• Power interruption or noise
occurred while safety
parameters were saved
√
P. A-131
246D0000 Motor
Non-conformity The Servo Drive and motor
combination is not correct. • The Servo Drive and motor
combination is not correct
√ P. A-132
28080000 Main Circuit Power
Supply Phase Loss
Error The phase loss of the main
circuit power supply was
detected • Incorrect wiring, for exam-
ple the single-phase power
supply is input to a 3-phase
input type Servo Drive
• In the case where the sin-
gle-phase power supply is
input to a single- and
3-phase input type Servo
Drive, the phase loss detec-
tion is enabled.
• The power supply voltage is
low or insufficient
• Broken wiring of the main
circuit power supply input
• Servo Drive failure
