Custom V/F Curve Setting:
A custom curve selection allows users to set parameters 01-02 ~ 01-13 whereas a predefined curve selection
does not.

The ‘SE03’ V/F curve tuning error is displayed when the frequency values are set incorrectly.
When 01-04 and 01-05 (or 01-18 and 01-19) are set to 0, the inverter ignores the set values of Fmin2 and Vmin2.
The voltage values for 01-02~01-09 become
irrelevant.
The value for maximum output voltage of the motor 1(01-03) and the value for base output voltage of the motor
(01-13) will depend on the initial setting of 13-08 which sets the value of voltage upon initialization.
When the control mode is changed parameter 00-00, 01-08 (F
min
) and 01-09 (V
min
) will automatically be changed
to the default setting of the selected control mode.
