Why is a braking resistor needed?
When the motor decelerates or brakes, it will switch to generator mode to generate electrical energy. This electrical energy will flow back to the DC bus of the frequency converter, causing the bus voltage to rise sharply.
Can the resistor work continuously?
No, its rated power is calculated based on a specific "load cycle". You need to select a "continuous operation" type braking resistor with a much higher power rating and recalculate and reconfigure the driver parameters.
As one of the key braking components of Siemens drive systems, the Siemens 6SL3055-0AA00-5BA3 pulse resistor is often used as an external option and can provide braking function for SINAMICS G120 or G120C frequency converters ranging from 3.0kW to 5.5kW. It can be used in combination with SINAMICS S120 book-type motor modules ranging from 1.5kW to 3.0kW to meet the rapid braking requirements.
