1.6. Definitions

Overtemperature.
controller is from 185 degrees F (85 degrees C) and above.
Overheating is unusual, but can occur if the transistor
controller is installed
overtemperature the drive current limit is linearly decreased
from full set current down to zero. Plug current is not reduced
by any thermal conditions to allow full plugging strength at all
times.
Undertemperature. When the transistor controller is
operating at less than −13 degrees F (−25 degrees C), the
current limit is cut back resulting in reduced travel speed and
acceleration.
Pulse Width Modulation. Pulse Width Modulation (PWM),
also called "chopping," controls the speed of the motor by
switching the battery voltage to the motor on and off very
quickly.
