Manual Torque Boost - Increasing Torque Boost At Low Speeds; Setting The Electronic Thermal - Toshiba TOSVERT VF-FS1 Instruction Manual

5.11 Manual torque boost - increasing torque boost at low
speeds
 : Torque boost 1
• Function
If torque is inadequate at low speeds, increase torque by raising the torque boost rate with this
parameter.

Title

Valid when  is set to  (V/F constant) or (square reduction)
Note: The optimum value is programmed for each inverter capacity. Be careful not to increase the torque boost
rate too much because it could cause an overcurrent trip at startup.

5.12 Setting the electronic thermal

 : Motor electronic-thermal protection level 1
 : Electronic thermal protection characteristic selection
 : Motor electronic-thermal protection level 2
 : Motor 150%-overload time limit
 : Thermal memory selection
• Function
This parameter allows selection of the appropriate electronic thermal protection characteristics according
to the particular rating and characteristics of the motor.
