P 3.3.3 Brake Resistor Power Limit
The parameter must be configured to set the expected average power dissipated in the brake resistor over a period of 120 s. To calculate
the brake resistor power limit, use the following formula.
The following elements are used in the formula:
P is the average power dissipated in the brake resistor.
