01 V/F Control Parameters
The V/F curve selection is enabled for V/F mode. Make sure to set the AC Drive input voltage parameter 01-14.
There are three ways to set V/F curve:
(1) 01-00 = 0 to 0E: choose any of the 15 predefined curves (0 to 17).
(2) 01-00 = 0F, use 01-02 to 01-09 and 01-12 to 01-13, with voltage limit
(2) 01-00 = FF, use 01-02 to 01-09 and 01-12 to 01-13, without voltage limit
Custom curves F and FF use identical curves to 0 (for 50Hz) or 1 (for 60Hz) as a baseline.
Parameters 01-02 to 01-13 are automatically set when any of the predefined V/F curves are selected.
Note:
Parameters 01-02 to 01-09 and 01-12 to 01-13 are only editable when 01-00=FF. (01-16 to 01-25 for motor 2)
V/F curve selection
Consider the following items as the conditions for selecting a V/F pattern.
(1) The voltage and frequency characteristic of motor.
(2) The maximum speed of motor.
