F1.2.18 Torque boost motor 1 Setting range: 0.0~20.0% Factory default: ☆
It is used to improve the inverter’s low frequency torque characteristics. When the inverter runs at low
frequency, it will make compensation for the inverter's output voltage. Its set value is the percentage relative
to the motor’s reference voltage [F1.2.16]. See Figure 7-27-A and Figure 7-27-B.
