Among the capacity range of 0.4 k to 7.5 k
the inverter is equipped with an internal
brake chopper as standard.
An improvement of the brake duty is
achieved by the use of an external brake
resistor with a higher rated capacity.
The duty cycle is selectable via parameter
30andcanbespecifiedtoupto30%via
parameter 70.

External Brake Resistors FR-ABR-(H)첸첸k
왎 Brake Units
For a braking torque higher than 20 % or a
duty cycle higher than 30 % an external
brake unit including the adequate brake
resistors has to be installed.
The brake units BU-UFS listed below are
cascadable so that the optimum
dimensioning can always be achieved.
Suggestions regarding an adequate
dimensioning of brake resistors can be
found in the operating manual for the
brake unit. Like any other documentation
of frequency inverters you will find the
operating manual on the MITSUBISHI
ELECTRIC homepage.
