Range:0 - 20 %
The forward and reverse torque boost value can be set separately. This function is
used to increase the output voltage to the motor at low speeds for a higher
volts/hertz ratio, resulting in a much higher starting current output to the motor. This
is for loads that require relatively higher torque than normal starting torque.
Note: If the torque boost is set too high an Overcurrent fault may occur. When this
occurs reduce the Torque Boost values.
