In most applications, Central Braking Modules are used only for occasional braking operations, but they are also
capable of handling continuous braking. The permissible braking power for load duty cycles and in continuous
operation is illustrated in the diagram below.
Standard load duty cycles and continuous braking power of Central Braking Modules
With the given standard load duty cycles, the following rated braking power results, when the upper response
threshold is selected and the braking units operate at the maximum possible DC link voltage:
Order number
Supply voltage 380 V – 480 V 3AC / DC link voltage 510 V – 720 V DC
6SL3700-1AE35-0AA3
6SL3700-1AE41-0AA3
Supply voltage 500 V – 600 V 3AC / DC link voltage 675 V – 900 V DC
6SL3700-1AF35-5AA3
6SL3700-1AF41-1AA3
Supply voltage 660 V – 690 V 3AC / DC link voltage 890 V – 1035 V DC
6SL3700-1AH36-3AA3
6SL3700-1AH41-2AA3
Standard braking power of Central Braking Modules
The procedure for calculating the required braking power of Braking Modules is described in detail in chapters
"Converter Chassis Units G130" and "Converter Cabinet Units G150". The essential principles of this procedure can
be applied to the calculation for the Central Braking Modules described here, although the following differences must
be taken into account.
§ The load duty cycle definitions for the built-in Braking Modules designed for integration in units of type
SINAMICS G130, G150 and S120 (Chassis and Cabinet Modules) are not the same as the load duty cycle
definitions for Central Braking Modules. This must be taken into account in the calculation.
§ The load duty cycle definitions for the Central Braking Modules and the associated braking resistors are not
identical, as the braking resistors are dimensioned only for occasional braking.
