DC braking

DC braking is used for applications without regenerative feedback into the line supply, where
the motor can be more quickly braked by impressing a DC current than along a braking
ramp.
Typical applications for DC braking include:
● Centrifuges
● Saws
● Grinding machines
● Conveyor belts
Whether DC braking or ramp-down with an OFF1 command is more effective depends on
the motor properties.
