For ATV312, How can we determine the minimum power/ Watt for a braking resistor?

Braking Resistor selection is very important specially for load require high braking torque

The below points are to be taken into consideration:
1- The Resistance value in Ohms
2- Power rating of the Resitor in Watt/KW
3- Calculation of the braking power

Refer to the curves below as well as the shown example
