Note 1: The optimum value is programmed for each inverter capacity. Be careful not to increase the torque boost

5.13 Setting the electronic thermal

• Function
This parameter allows selection of the appropriate electronic thermal protection characteristics according
to the particular rating and characteristics of the motor.

Torque boost 1
is set to 0 (V/F constant) or 1 (square reduction)
rate too much because it could cause an overcurrent trip at startup.
