Other Accessories: Regeneration Resistor/Regeneration Unit

Regeneration Resistor

During vertical operation (gravitational operation) or sudden start and stop with large inertia, an external force causes the motor to rotate and function as a power generator.
When the regenerative power exceeds the driver's regenerative power absorption capacitance, it may cause damage to the driver.
In such a case, connect the regeneration resistor and regeneration unit to the driver to convert regenerative power into thermal energy for dissipation.
