Braking resistor
The SINAMICS V90 has a built-in braking resistor. The table below shows the information of
the built-in resistor:
Power
supply
1/3-phase,
200 VAC to
240 VAC
3-phase,
200 VAC to
240 VAC
3-phase,
380 VAC to
480 VAC
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:
Power
supply
1/3-phase,
200 VAC to
240 VAC
3-phase,
200VAC to
240 VAC
3-phase,

480 VAC
