Tips: Differences among regenerative braking, dynamic braking and electromagnetic braking of servo motor

1. Regenerative braking can work only when servo motor operates normally. The motor cannot brake in some conditions, such as malfunction, emergency stopping, power off, etc. Dynamic brake and electromagnetic brake can work without power supply.
2. The regenerative braking can operate in system automatically, but dynamic braking and electromagnetic braking cannot operate without outer relay control.
3. Electromagnetic braking generally turns on after SV OFF, otherwise, it may cause the amplifier overload. Dynamic braking generally turns on after SV OFF or main circuit is shut off, otherwise, it may cause the dynamic braking resistor overheating.
