2.8 Selection of Regenerative Resistor

When the direction of pull-out torque is different from the rotation, it means the electricity is sent
back to the servo drive from the load-end. It becomes the capacitance of DC Bus and increases
the voltage. When the voltage increases to a specific value, the come-back electricity can only be
consumed by regenerative resistor. There is a built-in regenerative resistor in the servo drive.
Users can also use the external regenerative resistor if needed.
