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.

Regeneration Unit

Regeneration unit for DC input products only. Combined use of the regeneration unit suppresses the voltage rise inside the driver and the power supply voltage rise due to motor regeneration.
