The possible continuous braking power P
table of unit-specific technical data. They refer to the upper response thresholds, i.e. to V
voltages of 380 V to 480 V and to V
thresholds, the braking power must be reduced in proportion to V
The table below states the key technical data for SINAMICS S120 Motor Modules in their application as 3-phase
Braking Modules.

Technical data of 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
resistors. Allowance for the increase in resistance as a function of load (up to 30 %) must be included in the
calculation:
and the peak braking power P
