Functional Descriptions (By Parameter No.)

FREQUENCY RANGE (V/F PATTERN) (Parameter No. 03.)

A frequency range of 50/60Hz or 50 to 400Hz can be set independently from the maximum output frequency (50 to 400Hz).

Data setting value Name Remarks
50 50Hz mode The frequency range is set regardless of the

60 60Hz mode parameter No. 15 and 16 settings.
FF Free Mode The frequency range is set according to the parameter No. 15 and 16 settings.

The maximum output frequency is set in

parameter No. 15 and the base frequency

is set in parameter No. 16.

    (50Hz mode 60Hz mode Free mode
        (Notes)
        Both the maximum output frequency and base frequency are set to 50Hz as the factory setting data.
      1. Take note to the UPPER FREQUENCY CLAMP (parameter No. 55) when changing the maximum output frequency setting.
      2. The relationship of the output voltage to frequency is applied only during the V/F control (when parameter No. 65 is set to 0). The relationship is not applied during vector control (when parameter No. 65 is set to 1.)
