12.9.2 Selection
The dimensioning and selection of the components for the braking operation depend on
the continuous braking power, the peak braking power and the respective application.
The continuous braking power and peak braking power can be determined graphically:
ƒ Please observe emergency switching off concepts, if any.
Please provide for a safety shutdown in the event of overheating if a brake resistor or a
braking unit is used. Use the thermostats of the brake resistor or the braking unit to
ƒ disconnect all controllers from the mains and to set a controller inhibit (CINH) for all
controllers (terminal 28 = LOW / input RFR = LOW).
ƒ See example: (

)
Note!
Delayed braking of individual drives of the DC−bus system may reduce the
continuous braking power and the peak braking power.
Please observe the permissible overload capacity of the regenerative power
supply module and/or the switch−on cycle of the brake resistors.
