3.2.11 Dynamic Braking
The braking torque obtained by the application of frequency inverters without dynamic braking resistors varies
from 10 % to 35 % of the motor rated torque.
Braking resistors shall be used to obtain higher braking torques. In this case, the regenerated energy in excess is
dissipated in a resistor mounted outside the inverter.
This kind of braking is used in cases where short deceleration times are desired or when high-inertia loads are
driven.
The “Optimal Braking” feature may be used with the vector control mode, which eliminates in most cases the
need of an external braking resistor.
ATTENTION!
For the CFW-11M G2, use the DBW-04 braking module only. For further information, refer to the
manual of the accessory.
