1 - 04 Mid-Point Voltage (Vmid)
Settings
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).
1 - 05 Minimum Output Frequency (Fmin)
Settings
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).
1 - 06 Minimum Output Voltage (Vmin)
Settings
This parameter sets Minimum Output Voltage of the AC drive. This parameter must
be equal to or less than Mid-Point Voltage (Pr.1-04).
1 - 07 Upper Bound of Output Frequency
Settings
This parameter must be equal to or greater than the Lower Bound of Output Frequency
(Pr.1-08). The Maximum Output Frequency (Pr.1-00) is regarded as 100%.
