7.1.7 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.

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.
