Motor derate is a process in which a truck's engine cools off after reaching a certain threshold temperature. It limits the motor's power and torque to less than 75 percent of its rated power. The goal of limiting the derate is to minimize impact on the performance of the truck and to prevent forced shutdowns at reasonable effective grades.If you're wondering about SCR Error Torque Derate 25, look no further.
