Applicable Load Inertia
The drivable load inertia ratio (load inertia/rotor inertia) depends on the configuration and rigidity
of the machine being driven. Machines with high rigidity can be operated with a large load inertia.
Select the appropriate Servomotor and confirm the applicable load inertia.
Frequently operating a dynamic brake with a large load inertia may burn the dynamic brake
resistor. Do not turn ON/OFF the Servomotor frequently with the dynamic brake enabled.
