id-Point Voltage (Vmid)
Factory Setting: d12.0
Settings d 2.0 to d 255V Unit: 0.1V
The parameter sets the Mid-Point Voltage of any V/F curve. With this setting, the V/F
ratio between Minimum Frequency and Mid-Point Frequency can be determined. This
parameter must be equal to or greater than Minimum Output Voltage (Pr.1-06) and equal
to or less than Maximum Output Voltage (Pr.1-02).

inimum Output Frequency (Fmin) Factory Setting: d 1.0
Settings d 1.0 to d 60.0Hz Unit: 0.1Hz
This parameter sets the Minimum Output Frequency of the AC drive. This parameter
must be equal to or less than Mid-Point Frequency (Pr.1-03).
