Problems with LOAD feature

<< < (2/2)

Alan:
A point of clarification...

When RP reports motor overload it isn't actually measuring the temperature of the motor itself. There is no temperature sensor attached to the motor. What is actually being over-driven (overheating) are the output transistors in the LM PWM drive circuit.

Functionally, it is all the same. Just wanted to clarify in case someone was wondering how the LM knows the motor temperature. It doesn't. But it does know how much current is flowing through the output transistors and their temperature.
