F09 Torque boost
Determines the torque boost for torque vector control. Basically, there is no need to modify the
default setting. If you need more torque, please change the value. However, as too much setting of
F09 may cause larger current, do not modify the default setting unless it is necessary.
- Data setting range: 0.0 to 5.0
It is a special code of the torque vector control.
Refer to page 2-2 for the control mode of the inverter.
F10 Electronic Thermal Overload Protection for Motor (Select motor characteristics)
F11 Electronic Thermal Overload Protection for Motor (Overload detection level)
F12 Electronic Thermal Overload Protection for Motor (Thermal time constant)
F10 through F12 specify the thermal characteristics of the motor for its electronic thermal overload
protection that is used to detect overload conditions of the motor by the inverter.

Select motor characteristics (F10)
F10 specifies the cooling mechanism of the motor: built-in cooling fan or externally powered
forced-ventilation fan.
Data for F10 Function
1
For general-purpose motors with built-in self-cooling fan
(The cooling effect will decrease in low speed operation.)
2
For inverter-driven motors or high-speed motors with forced-ventilation fan
(The cooling effect will be kept constant regardless of the output speed.)
3
For general-purpose motors with built-in self-cooling fan (Mode2)
(The cooling effect will decrease in low speed operation.)
About F10=1 or 3.
The figure below shows operation characteristics of the electronic thermal overload protection.
