01 - V/f Control Parameters
Code Parameter Name / Range
01-00 V/f curve selection
0~FF
The V/f curve selection is enabled for V/f mode with or without PG or SLV2 mode. Make sure to set the inverter
input voltage parameter 01-14.
There are three ways to set V/f curve:
(1) 01-00 = 0 to E: choose any of the 15 predened curves (0 to E).
(2) 01-00 =0F, use 01-02~01-09 and 01-12~01-13, with voltage limit.
(3) 01-00 = FF: use 01-02~01-09 and 01-12~01-13, without voltage limit.
Refer to the following gure.
Output

40
(the output frequency in the max. voltage)
The Output Voltage Limit Curve
(the voltage limit of 400V class
is two times.)
0
5V
40V
250V
The default parameters (01-02~01-09) are the same when 01-00 is set to F (default) and 01-00 is set to 1.
Parameters 01-02 to 01-13 are automatically set when any of the predened V/f curves are selected.
Note: This parameter is not affected by the initialization parameter (13-08).
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.
