The diagram below illustrates how FX BOOST alters the V/Hz ratio to increase motor
torque.
The FX BOOST setting represents the amount of boost at 0 Hz (approximately 15% in the
example below), and as the output frequency approaches 30 Hz, the boost decreases to
zero. Therefore, at 30 Hz and above, the V/Hz ratio returns to its “normal” state.

22 TORQUE (TORQUE CURVE SELECTION)
This parameter is used to select whether the output of the drive follows a constant or
variable V/Hz curve. The following selections are available:
CONSTANT Use for constant torque applications to optimize torque.
VARIABLE Use for variable torque applications to optimize energy savings.
CT / NOCMP Use for constant torque applications that require full overload
capacity at low speeds (refer to Parameter 17 - MOTOR OL).
