Tip!
Independent of the selected motor control, all procedures given in
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
(
= "4: Brake resistor + FI_MotBrk + RfgStop").
