5 Basic Settings
• Automatic torque boost controls to match the motor characteristics. Either set Base Frequency (F04/
A02), Rated Voltage at Base Frequency (F05/A03) and motor parameters (P01/A15 to P03/A17 and
P06/A20 to P20/A34) to match the motor capacity or motor characteristics, or execute auto-tuning.
Manual Torque Boost (E112/E113 = 0)
• With the torque boost by Manual Torque Boost Voltage (F09/A05), a constant voltage is added to
the V/f characteristics before output regardless of the load. The optimum voltage suited to the motor
and load are manually adjusted by the Manual Torque Boost Voltage (F09/A05) to ensure starting
torque. Adjust the voltage to a level at which startup is possible and overexcitation does not occur in
a no-load state or light load state.
• When the non-linear V/f function is used in combination with the manual torque boost function, the
torque boost is enabled at the lowest non-linear V/f frequency or less.
• When Manual Torque Boost Voltage (F09/A05) is set to 0.0%, manual torque boost is disabled.
