Braking power with external brake resistance

The following load cycles are defined for the braking modules of the 20 kW and 40 kW Basic Line Modules:

The maximum possible braking power P_max is calculated using the following formula:

P _max = U²/R

U = Activation threshold

R = Resistance value of the external braking resistor

The maximum braking power is achieved with the smallest permissible resistance value. The maximum possible braking power falls at larger resistance values.

Braking power of the 20 kW Basic Line Modules depending on the connected braking resistor

When the recommended braking resistor is used, the following values result for the maximum braking power or continuous braking power:

Braking resistor 6SE7023?2ES87?2DC0
Resistance value = 20 ? > max. braking power = 30 kW;
continuous braking power = 5 kW

Braking power of the 40 kW Basic Line Modules depending on the connected braking resistor

When the recommended braking resistor is used, the following values result for the maximum braking power or continuous braking power:

Braking resistor 6SE7028?0ES87?2DC0
Resistance value = 8 ? > max. braking power = 75 kW;
continuous braking power = 10 kW (limited by braking module)
