3-4．Regenerative Resistor
When the servo motor operates in generator mode, power is returned to the servo drive
side. This is called regenerative power. The regenerative power is absorbed by charging
the smoothing capacitor, but when the capacitor’s charging limit is exceeded, the
regenerative power needs to be reduced by the regenerative resistor.
The servomotor is driven in regeneration (generator) mode in the following conditions:
 From decelerating to stop for acceleration/deceleration operation.
 Move down on the vertical axis.
 The external load drives the motor running
