Formula for Calculating the Resistor Value

Rbr -

Resistor value of the braking resistor [Ω]; value must be greater than the minimum resistor value determined for each type of  drive

Vbr - Braking voltage for the drive [V]; typical value for 230V drive is 360V and for the 400..480V drive is 780V
Pbr_max - Maximum braking power of the braking resistor [W]

Calculation

Inputs:

Vbr = V Pbr_max = W

Result:

[Ω]
