Operating Instructions, 04/2019, A5E36037884-007
When the motor works in a fast round-trip process, the voltage of the line supply increases.
The braking resistor starts to work if the voltage reaches the set threshold. The temperature
of the heat sink increases (>100 °C) when the braking resistor is working. If alarms A52901
and A5000 appear at the same time, you need to switch the built-in braking resistor to the
external braking resistor. You can select a standard braking resistor according to the table
below:

Note
When selecting a braking resistor, you must take into account the factors such as braking
inertia, deceleration time, speed variation, and braking period according to your specific
application and technology. The resistance of the selected braking resistor must not be lower
than the minimum resistance listed above.

Line filter
Siemens recommends you to use a line filter to protect the system from high frequency noise.
The line filter restricts the conductive interference emitted from the SINAMICS V90 to the
permissible values. The SINAMICS V90 drives with these external line filters have been
tested in accordance with the emission requirements of the Category C2 environment. The
conductive emissions and radiated emissions are in compliance with the Class A
requirements of the EN 55011 standard.
