Tip!
Independent of the selected motor control, all procedures given in

C00175

can be used.

The actual speed value can optimally follow the speed setpoint when a brake resistor is

used.
If it is possible to dispense with exact adherence to the deceleration ramp in simple

applications, selection of a braking method without an external brake resistor enables

costs to be reduced due to the avoidance of having to use a brake resistor .
With the "inverter motor brake" function, an effective braking torque of 10 ... 20 % of the

rated motor torque can be achieved.
A combination of all three braking procedures is also possible, e.g. for emergency braking if

the brake resistor fails
