Regen Resistor Sizing and Configuration Xenus Regeneration Guide 2 Copley Controls Corp. 1.1: Regen Resistor Theory When a load is accelerated electrical energy is converted into mechanical energy. During deceleration the conversion is reversed. This is called regeneration. Some of this regenerated energy is lost to friction in the mechanical system. More of this energy is converted to heat due to I2R losses in the motor windings, cabling and drive electronics. The remainder of the energy is added to the electrical energy already stored in the internal capacitor bank of the amplifier. The...
