FW block:
45.01 MOT TEMP
The temperature is supervised based on the motor thermal protection
model, which uses the motor thermal time constant (parameter
MOT THERM
45.06...45.08). User tuning is typically needed only if the ambient
temperature differs from the normal operating temperature specified
for the motor.
The motor temperature increases if it operates in the region above the
motor load curve. The motor temperature decreases if it operates in
the region below the motor load curve (if the motor is overheated).
