When and why to use Dynamic Braking Resistor in VFD

When and why to use Dynamic Braking Resistor in VFD   Dynamic breaking resistor is used where motor connected to VFD which is generating regenerative energy due to high inertia or in case where deceleration time is so less that VFD cannot control motor to stop. Due to high inertia motor acts as a generator and starts producing energy. This energy is feed back to…
