6.1.7 Setting the braking
The braking types of servo drive include three kinds: 1.dynamic braking 2.energy-consumption braking
3. Electromagnetic braking.

Dynamic braking
Dynamic braking is a common way to stop servo motor. It is a kind of special energy-consumption braking
mode. The braking circuit includes dynamic braking resistor and diode. The method of dynamic braking is to
short-connect drive line coil of servo motor, to shorten motor mechanical feed distance by modes of energy
consumption braking finally.

Setting function
Fast enable: after servo is power on, relay is switched on. After enable signal is valid, servo will be ON after 10ms.
!
Caution
Energy-consumption braking is valid after main circuit is powered on.
Electromagnetic braking starts after servo OFF. If it is not, overload malfunction will occur.
Dynamic braking starts after servo OFF or main circuit is powered off. But if motor rotation speed is too
high, dynamic braking resistor will be overheat.
