VFD700 AC Drive Getting Started Guide 65
1: Open loop vector control 1
2: Open loop vector control 2
Note: To use open loop vector control mode 1 or 2, please set up motor parameters correctly
(rated voltage, current, pole pairs, rated speed) and finish auto-tune.

Switch frequency can affect the motor noise and drive power loss, the higher switch frequency,
the lower motor noise, but the bigger IGBT power loss.

Different V/F characteristic is defined by P00.23 to meet the demands from different load.
There are three kinds of fixed curve and one user programmed line
When P00.23 (P06.01) is 0, user can define different fold lines by setting P06.02
～
P06.07,
and adding three points, (V1, F1)
、
(V2, F2)
、
(V3, F3) to define the V/Flines mode.
The default V/Fis a straight line, as the line 0 in Figure 4-2.
When P00.23 (P06.01) is set to 1, it is a 2.0 law ramp, as curve 1 in figure 4-2.
When P00.23 (P06.01) is set to 2, it is a 1.7 law ramp, as curve 2 in figure 4-2.
When P00.23 (P06.01) is set to 3, it is a 1.2 law ramp, as curve 3 in figure 4-2.
