See also section Brake chopper
Displays the estimated temperature of the brake resistor, or
how close the brake resistor is hot.
The value is given in percent, where 100% is the eventual
temperature that the resistor will reach when loaded long
enough with its rated maximum load capacity
resistor Pmax cont).
Temperature calculation is based on the values defined in
parameters 43.08, 43.09
that the resistor is installed as instructed by the
manufacturer (i.e., it cools down as expected).
This parameter is read-only.
Estimated brake resistor temperature.
Enables brake chopper control.
Note: Before enabling brake chopper control, ensure that
• a brake resistor is connected
• the supply voltage range (parameter
voltage) has been selected correctly.
