Parameterizing a DC & compound brake
Applications for a DC brake and compound brake
DC and compound brakes are especially used for centrifuges, saws, grinding machines, and
conveyor belts.
CAUTION
With DC and compound brakes, the kinetic energy of the motor and motor load is partially
converted into thermal energy. If the braking procedure lasts too long, this can cause the
motor to overheat.
Note
The compact brake is only active in conjunction with the V/f control.
The compound brake is deactivated, if:
•
The "flying restart" function is active
•
The DC brake is active
•
Vector control is selected
The switch-on limit value for the compound brake V
DC-Comp
depends on P1254
