(1) Regenerative Power Selection
(a) When the external load on torque does not exist
If the motor operates back and forth, the energy generated by the brake will go into the
capacitance of DC bus. When the voltage of the capacitance exceeds a specific value, the
redundant energy will be consumed by regenerative resistor. Two ways of selecting
regenerative resistor are provided here. The table below provides the energy calculation
method. Users can refer to it and calculate the selected regenerative resistor.
