 Note 
The drives of 75kWG / 90kWP and below have built-in braking unit or can customize built-in braking unit. The 
user only needs to configure external braking resistor when the dynamic braking is required. The drives of 
90kWG / 110kWP and above need external braking unit, the wiring between the external braking unit and the 
drive, braking resistor selection, etc.,please follow the guidance of external braking unit suppliers.
