Calculate of Braking resistor value:
The Braking resistor value is related to the DC currency when the
inverter braking. For 380V power supply, the braking DC voltage is
800V-820V, and for 220V system, the DC voltage is 400V.
Moreover, the Braking resistor value is related to braking torque
Mbr%, and to the different braking torque the Braking resistor values
are different, and the calculation formula is as follow:
