Torque boost value 1 0.0 - 30.0 (%)
According to model
(Refer to section 11.4)
● Valid when  is set to 0 (V/F constant), 1 (Variable torque), or 7 (V/F 5-point setting).
Note 1: The optimum value is programmed for each inverter capacity by default setting. Be careful not to increase
the torque boost rate too much because it could cause an overcurrent trip at startup.
