The heating and cooling curves are based on WEG's extensive
experience with motor development. These curves adopt WEG
three-phase IP55 standard motors. They also consider if the motor
is force cooled or not when driven.
The cooling time of the thermal image depends on the motor power,
which means that each different power rating will have different cooling
times. When reduction of this cooling time is required, you can use P641.
The estimated motor temperature is saved in non-volatile memory
every time the power supply of the control board is switched off. Thus,
when the control board is switched on again, the last value saved will
return.
