method
*1. Select a combination that has an absorption capacity greater than the average regeneration power (Pr).
*2. Do not use a combination of resistors with a resistance lower than the minimum external regenerative
resistance of each Servo Drive. For information on the minimum external regenerative resistance, refer to
Servo Drive Regenerative Energy Absorption Capacity on page 4-35.

Thermal Switch Output

Regeneration
Resistor
Connect the thermal switch output so that the power supply is shut OFF
when the contacts open. Configure a sequence to shut OFF the power via
the thermal output. Not doing so may cause the resistor to overheat,
resulting in a fire or damage to the equipment.
