12.8.2 Selection
The selection of components for braking operation depends on the continuous
braking power, peak braking power and the application.
The permanent braking power and peak braking power can be determined
graphically:
l Example: (¶ 12.5-9)
l
Please observe possibly available emergency off measures.
Provide a safety shutdown in the event of overheating, if you use a braking resistor
or braking unit. Use the thermostat of the braking resistor or braking unit to
l disconnect all controllers from the mains.
l set controller inhibit (CINH) in all controllers (terminal 28 = LOW).
l Example: (¶ 12.7-2)

))
) Note!
Subsequently braking of single drives of the network can reduce
the permanent and the peak braking power.
Observe the permissible overload capacity of the regenerative
power supply unit or the switch-on cycle of the braking resistor.
