VFD-B Series

5-6

 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). However, this parameter is

ineffective when Pr.11-00 is set to 1 to 4.

01 - 05

Minimum Output Frequency (Fmin) Factory Setting: 0.50

Settings 0.10 to 400.00Hz Unit: 0.01Hz

 This parameter sets the Minimum Output Frequency of the AC drive. This parameter

must be equal to or less than Mid-Point Frequency (Pr.01-03).

 The settings of 01-03, 01-04, 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. 7V

460V series 0.1 to 510.0V Factory setting: 3.4V

 This parameter sets the Minimum Output Voltage of the AC 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 agreement that Pr.01-02 ≥

Pr.01-04 ≥ Pr.01-06 and Pr.01-01 ≥ Pr.01-03 ≥ Pr.01-05.

01 - 07

Upper Bound of Output Frequency Factory Setting: 100

Settings 1 to 120% Unit: 1%

 This parameter must be equal to or greater than the Lower Bound of Output Frequency

(Pr.01-08). The Maximum Output Frequency (Pr.01-00) is regarded as 100%.

 Upper Bound of Output Frequency value = (Pr.01-00 x Pr.01-07)/100
