[ 1 ] Braking resistors
A braking resistor converts regenerative energy generated from deceleration of the motor and converts it
to heat for consumption. Use of a braking resistor results in improved deceleration performance of the
inverter.

Refer to Chapter 7, Section 7.2 "Selecting a Braking Resistor."
[ 1.1 ] Standard model
The standard model of a braking resistor integrates a facility that detects the temperature on the heat sink
of the resistor and outputs a digital ON/OFF signal if the temperature exceeds the specified level (as an
overheating warning signal). To ensure that the signal is recognized at one of the digital input terminals of
the FRENIC-Mini, assign the external alarm (THR) to any of terminals [X1] to [X3], [FWD] and [REV].
Connect the assigned terminal to terminal [1] of the braking resistor. Upon detection of the warning signal
(preset detection level: 150qC (302qF)), the inverter simultaneously transfers to Alarm mode, displays
alarm
J on the LED monitor and shuts down its power output.
