Description
The Regeneration Load
Ratio (4310-81 hex)
exceeded the regeneration
overload ratio.
The position deviation is
greater than or equal to the
value set in the Following
error window.
The speed deviation is
greater than or equal to the
value set in the Excessive
Velocity Deviation Detec-
tion Level.
The feedback motor speed
is greater than or equal to
the value set in the Exces-
sive Speed Detection Level.
The following error value
exceeded the range from
-2147483648 to
2147483647.
The multi-rotation counter of
the encoder exceeded the
maximum number of rota-
tions.
Safety process data com-
munications were not estab-
lished with the Safety CPU
Unit because of an incorrect
communications setting.

Assumed cause
• 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
• The motor operation does
not follow the command
• The value of Following error
window is small
• 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
• The velocity command
value is too large
• Overshooting occurred
• The motor was rotated by
external forces
• The motor operation does
not follow the command
• The motor is rotated or lim-
ited on the operation by
external forces
• 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
• The watchdog time was set
incorrectly
• The processing was not
completed within the watch-
dog time because commu-
nications were not
established due to the noise
