Revision July 2008, BE16, SW V4.08 & V5.00 5-29
01 - 04 Mid-Point Voltage (Vmid) Unit: 0.1
Settings 230V series 0.1 to 255.0V Factory Setting: 1.7
460V series 0.1 to 510.0V Factory Setting: 3.4
575V series 0.1 to 637.0V Factory Setting: 4.8
 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) Unit: 0.01
Settings 0.10 to 400.00Hz Factory Setting: 0.50
 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) Unit: 0.1
Settings 230V series 0.1 to 255.0V Factory Setting: 1.7
460V series 0.1 to 510.0V Factory Setting: 3.4
575V series 0.1 to 637.0V Factory Setting: 4.8
 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 Unit: 1
Settings 1 to 120% Factory Setting: 100
 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.
