-1 Error List
38810000 Overload Error The Load Ratio of Servo
Drive or motor (4150-81
hex) exceeded 100%. • Operation was continued
for a long time with high
load
• There is incorrect wiring of
the motor cable or a broken
cable
• Increase in friction
√
P. A-137
38820000 Regeneration Over-
load Error The Regeneration Load
Ratio (4310-81 hex)
exceeded the regeneration
overload ratio. • The regeneration process-
ing is set inappropriately
• The Regeneration Resistor
is selected inappropriately
• The Regeneration Resistor
is used for continuous
regenerative braking
• The applied power supply
voltage is higher than the
specified value
• Regeneration Resistor fail-
ure
√ P. A-138
38830000 Excessive Position
Deviation Error The position deviation is
greater than or equal to the
value set in the Following
error window. • The motor operation does
not follow the command
• The value of Following error
window is small
√ P. A-139
38840000 Excessive Speed
Deviation Error The speed deviation is
greater than or equal to the
value set in the Excessive
Velocity Deviation Detection
Level. • The motor operation does
not follow the command
because a parameter value
is inappropriate
• The output axis of motor is
limited on the operation by
external forces
• The value of the Excessive
Velocity Deviation Detection
Level is inappropriate
√ P. A-140
38850000 Excessive Speed
Error The feedback motor speed
is greater than or equal to
the value set in the Exces-
sive Speed Detection Level. • The velocity command
value is too large
• Overshooting occurred
• The motor was rotated by
external forces
√
P. A-141
38860000 Following Error
Counter Overflow The following error value
exceeded the range from
-2147483648 to
2147483647. • The motor operation does
not follow the command
• The motor is rotated or lim-
ited on the operation by
external forces
√
P. A-142
38870000 Absolute Encoder
Counter Overflow
Error The multi-rotation counter of
the encoder exceeded the
maximum number of rota-
tions. • An inappropriate value was
set in the Encoder - Opera-
tion Selection when Using
Absolute Encoder
(4510-01 hex)
• The multi-rotation number
of the encoder exceeded
the maximum number of
rotations
