Mid-Point Voltage (Vmid)

Settings
This 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.01-06) and equal to or less than
Maximum Output Voltage (Pr.01-02).
This parameter is ineffective when Pr.11-00 is set to 1 to 4.
01 - 05

Minimum Output Frequency (Fmin)

Settings
This parameter sets the Minimum Output Frequency of the AC motor drive. This parameter
must be equal to or less than Mid-Point Frequency (Pr.01-03).
The settings of 01-03, 01-04, and 01-06 are invalid in Vector Control mode.
01 - 06

Minimum Output Voltage (Vmin)

Settings
This parameter sets the Minimum Output Voltage of the AC motor drive. This parameter must
be equal to or less than Mid-Point Voltage (Pr.01-04).
The settings of Pr.01-01 to Pr.01-06 have to meet the condition of Pr.01-02 ≥ Pr.01-04 ≥ Pr.01-
06 and Pr.01-01 ≥ Pr.01-03 ≥ Pr.01-05.
01 - 07

Output Frequency Upper Limit

Settings
This parameter must be equal to or greater than the Output Frequency Lower Limit (Pr.01-08).
The Maximum Output Frequency (Pr.01-00) is regarded as 100%.
Output Frequency Upper Limit value = (Pr.01-00 * Pr.01-07)/100.
