Description
More than one function out-
put is allocated to one gen-
eral output.
The dividing numerator
exceeded the dividing
denominator when the
Encoder Dividing Pulse
Output - Dividing Denomi-
nator was set to a value
other than 0.
The connected motor is dif-
ferent from the motor that
was connected the last
time.
The electronic gear ratio
exceeded the allowable
range.
The internal temperature of
Servo Drive exceeded the
circuit protection level.
The Load Ratio of Servo
Drive or motor (4150-81
hex) exceeded 100%.
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.
Assumed cause
• More than one function out-
put is allocated to one gen-
eral output
• The dividing numerator
exceeded the dividing
denominator when the
Encoder Dividing Pulse
Output - Dividing Denomi-
nator was set to a value
other than 0
• The motor was replaced
• The Servo Drive was
replaced
• The electronic gear ratio
exceeded the allowable
range
• The ambient temperature of
the Servo Drive exceeded
the specified value
• Overload
• 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
• 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
