Braking methods depending on the application
Advantage:
The motor is braked without the inverter having to convert the braking
energy
Disadvantages:
significant increase in the motor temperature; no defined braking
characteristics; no constant braking torque; no braking torque at standstill; braking
energy is lost as heat; does not function when the power fails.
Advantages:
defined braking characteristics; no additional motor temperature
increase; constant braking torque; in principle, also functions when the power fails
Disadvantages:
A braking resistor is required; braking energy is lost as heat; the
permissible load of the braking resistor must be taken into account.
