Remedy
Check the operation pattern (velocity
monitor). Check the Regeneration
Resistor load rate and the excessive
regeneration warning, and perform
the following accordingly.
• Increase the capacities of the
Servomotor and the Servo Drive.
• Increase the deceleration time.
• Reduce the Servomotor rotation
speed.
• Use an External Regeneration
Resistor.
• Set the Regeneration Resistor
Selection (3016 hex) to 2.
This Regeneration Resistor cannot be
used for continuous regenerative
braking.

Prevention
Check the items given for corrections
in advance and implement
countermeasures as required. Or, set
the Regeneration Resistor Selection
(3016 hex) to 2.
Do not use the Regeneration Resistor
for continuous regenerative braking.
