
Max output frequency depends on parameter 01-00 , for 01-00=【7】It can be set by parameter
01-02.
For 01-00 ≠【7】, the maximum output frequency depends on parameter 00-12, frequency

01-10 Volts/Hz Curve Modification (Torque Boost)
【0 ~ 10.0】%
Range

Inverter output V / F curve settings for points B, C can be adjusted by parameter 01-10 to
improve the output torque.

Calculation of B, C point voltage: B point voltage = Xb × maximum output voltage, C point
voltage = Xc × maximum output voltage (Xb, Xc see 01-00). When 01-10 = 0, the torque
improvement is disabled.
