Cool down timer:
After motor stop, the cool down timer countdown to simulated the motor cools to a safe state
process; the definition of the cooling time is to reach steady state of ambient temperature (the
maximum allowable temperature) when motor overload trip. Typically, cool timer can set to 30
minutes as heat capacity values decreased from 100% to 15%.
