These externally-mounted passive shunt modules provide a means for servo drives to dissipate excess regenerative energy from the DC bus. This is needed when system loads require power dissipation beyond the capability of the shunt resistor internal to the servo drive. These are passive shunt resistors and require transistor activation by the servo drive. A properly-sized shunt module regulates excessive bus voltage by passing current through a resistor, which dissipates the current as heat and minimizes drive faults caused by excess bus voltage.
