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 capacity (
The temperature calculation is based on the values of
parameters
,
, and on the assumption
that the resistor is installed as instructed by the manufacturer
(ie. it cools down as expected).
This parameter is read-only.

0.0 … 120.0%
Estimated brake resistor temperature.
1 = 1%
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
), and
• the supply voltage range (parameter
has been selected correctly.
Disabled
Brake chopper control disabled.
0
Enabled with
thermal model
Brake chopper control enabled with resistor overload
protection based on a thermal model. If you select this, you
must also specify the values needed by the model, ie.
