Default See table below
Update rate Background read
This parameter defines the time period that the braking resistor installed can stand full braking volts without damage. The setting of this parameter is
used in determining the braking overload time.
For DST1xxxx drives the default value is a suitable value for standard braking resistors that can be mounted within the drive as given in the table
below.
Drive voltage rating
200V
400V
If Pr 10.30 is set to zero then the braking resistor thermal protection system is disabled.
