Cause and
correction
Assumed cause Correction Prevention
The regeneration processing is
set inappropriately
Check the regeneration process-
ing setting, and set the same value
as the resistance value of the
Regeneration Resistor in use.
Check the items given for correc-
tions in advance and take counter-
measures as required.
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 continuous regenera-
tive braking
The Regeneration Resistor can-
not be used for continuous regen-
erative braking.
Do not use the Regeneration
Resistor for continuous regenera-
tive braking.
The applied power supply volt-
age is higher than the specified
value
Apply the power supply voltage to
be the specified value.
Review the power supply voltage
to be the specified value before
use.
Regeneration Resistor failure Check whether the Regeneration
Resistor is faulty, and use one
without failures.
Confirm that the Regeneration
Resistor is not faulty before use.
