2.8 Selecting the regenerative resistor

Some of the Delta servo drive models have a built-in regenerative resistor, and you can use an
2
external regenerative resistor if needed. When the direction of torque is opposite to the direction
of rotation, the energy generated returns to the servo drive from the load. This energy is turned
into electricity in the capacitor of the DC Bus and thus increases the voltage. When the voltage
reaches a given value, the excess energy is consumed by a regenerative resistor. Refer to the
following table to select the suitable regenerative resistor.
