Calculate of braking resistance value:
The braking resistance value is related to the DC currency when
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 resistance value is related to braking
torsion Mbr%. The braking resistance values are different for the
different braking torsion. The calculation formula is as follow:

The braking power is related to braking torsion and braking
frequency. The above illustration shows the braking torsion as
125% and the frequency is 10%. The different loading is by
situations, the data in the illustration are for reference.
