I2T Motor Overload Algorithm
The purpose of the motor overload algorithm is to protect the motor from heat damage. The I2T algorithm
protects the motor by modeling the heat buildup in the motor.
Figure 193: I2T Motor Overload Algorithm
The graph above shows the time it takes for the system to progress from normal running to an overload as
a function of 2 factors:
•
Amount of overload: The higher the overload, the faster the system will shut down.
