Percentage.
Settings for the internal brake chopper.
Displays the estimated temperature of the brake
resistor, or how close the brake resistor is to being
too hot.
The value is given in percent where 100% is the
eventual temperature the resistor would reach when
loaded long enough with its rated maximum load

assumption that the resistor is installed as instructed
by the manufacturer (ie, it cools down as expected).
Estimated brake resistor temperature.
Enables brake chopper control and selects the brake
resistor overload protection method (calculation or
measurement).
Note: Before enabling brake chopper control, ensure
that
• a brake resistor is connected
• overvoltage control is switched off (parameter
30.30 Overvoltage control
• the supply voltage range (parameter
voltage
) has been selected correctly.
Brake chopper control disabled.
Brake chopper control enabled with the brake resistor
protection based on the thermal model. If you select
this, you must also specify the values needed by the
model, ie. parameters
43.12
and . See the resistor manufacturer data sheet.
Brake chopper control enabled without resistor
overload protection based on the thermal model if
the resistor is equipped with a thermal switch that is
wired to open the main contactor of the drive if the
resistor overheats.
