Regenera-
tion Over-
load Error
The Regeneration Load
Ratio (4310-81 hex)
exceeded the regenera-
tion overload ratio.
The regeneration pro-
cessing is set inappro-
priately.
Check the regeneration processing
setting, and set the same value as
the resistance value of the Regen-
eration Resistor in use.
The Regeneration
Resistor is selected
inappropriately.
Check the operation pattern by the
velocity monitor. Check the load
ratio of Regeneration Resistor, and
perform the following corrections
accordingly.
• Increase the deceleration time
and stopping time.
• Decrease the command velocity
to the motor.
• Use an External Regeneration
Resistor.
• Increase the capacities of the
Servo Drive and the motor.
The Regeneration
Resistor is used for con-
tinuous regenerative
braking.
The Regeneration Resistor cannot
be used for continuous regenera-
tive braking.
The applied power sup-
ply voltage is higher
than the specified value.
Apply the specified power supply
voltage.
Regeneration Resistor
failure
Check whether the Regeneration
Resistor is faulty, and use one with-
out failures.
01
Regenera-
tion Circuit
Error
*2
An regeneration circuit
error was detected.
There is a short circuit
between B2 and N2/N3.
Perform the correct wiring, referring
the cases of the connection with
peripheral devices.
Regeneration circuit fail-
ure
Replace the Servo Drive.
Noise into wiring of the
external regeneration
registor.
Take noise countermeasures by
shortening wiring or the like.
02
Regenera-
tion Process-
ing Error
The regeneration pro-
cessing was stopped to
protect the Regenera-
tion Resistor.
This error occurs when
the regeneration pro-
cessing continues for
500 ms or more.
The regeneration pro-
cessing is set inappro-
priately.
Check the regeneration processing
setting, and set the same value as
the resistance value of the Regen-
eration Resistor in use.
Error No.
