almost all drive applications. It must be noted that in this case, the bottom-mounted brake resistors
must be mounted close to the inverter.
Above an inverter power of > 55 kW or for greater required continuous powers or brief powers, a
suitable brake resistor must be planned, as the necessary parameters can no longer be achieved with
a sensible combination of brake resistors from the standard range.
