The possible continuous braking power P
rated-Brake
and the peak braking power P
max-Brake
are included in the following
table of unit-specific technical data. They refer to the upper response thresholds, i.e. to V
DC-max
= 774 V at line supply
voltages of 380 V to 480 V and to V
DC-max
= 1158 V at line supply voltages of 500 V to 690 V. For other response
thresholds, the braking power must be reduced in proportion to V
DC-Brake
.
The table below states the key technical data for SINAMICS S120 Motor Modules in their application as 3-phase
Braking Modules.

Dimensioning of the braking resistors
The formula below defines the required limits of the resistance values R
BR
of the three star-connected braking
resistors. Allowance for the increase in resistance as a function of load (up to 30 %) must be included in the
calculation:
R
BR-min
