When and How Should I Select a Braking Resistor?
When designing a motor control system, it is not always clear if a braking resistor is required and, if it is, how to proceed in selecting a braking resistor. This post is intended to simplify that process so it is clear when and how to select a braking resistor for your application.
Why are braking resistors necessary?
Braking resistors are introduced into a motor control system in order to prevent hardware damage and/or nuisance faults in a VFD. They are required because in certain operations, the motor controlled by the VFD is acting as a generator and power is flowing back towards the VFD, rather than towards the motor.

New Product
Maplesoft™ announced the release of MapleSim™ Insight, a new software product from Maplesoft that gives machine builders powerful, simulation-based debugging and 3-D visualization capabilities that directly connect to their automation tools. As a result, engineers can perform simulation-based testing of their controller easily and efficiently.
Simulation-based testing of machine control strategies is a key element of virtual prototyping and using digital twins for virtual commissioning. However, this step can be cumbersome, as many automation tools provide limited options for machine-level, simulation-based controller testing, and these options often require moving development to an entirely new platform.

Danfoss: Facts Worth Knowing about AC Drives - Inverters, Modulation Principles, Control Circuit and Methods
By Danfoss Drives
The inverter is the last of the main elements making up the AC drive. The inverter processes represent the final stage in terms of generating the output voltage and frequency. When the motor is connected directly to the mains, the ideal operating conditions apply at the rated operating point.
The AC drive guarantees good operating conditions throughout the whole speed range by adapting the output voltage to the load conditions. It is thus possible to maintain the magnetization of the motor at the optimal value.
