Calculation of braking resistor value:
The braking resistor value is related to the DC current when the inverter is braking. At 400
V power supply, the DC voltage is 800 V to 820 V and for the 230 V system the DC voltage
is 400 V.
In addition, the braking resistance value refers to the braking torque Mbr%. The formula
for calculating the braking resistor value is as follows:
