power display value of motor 1. However, it
does not affect the control performance of the
1 VFD.
Setting range: 0.00–3.00
0: Display by motor type. In this mode, only
parameters related to the present motor type
are displayed.
1: Display all. In this mode, all the motor
parameters are displayed.

The parameters P03.00–P03.05 are applicable
only to vector control mode. Below the
switching frequency 1 (P03.02), the speed-loop
PI parameters are: P03.00 and P03.01. Above
the switching frequency 2 (P03.05), the
speed-loop PI parameters are: P03.03 and
P03.04. PI parameters are obtained according
to the linear change of two groups of
parameters. See the following figure:
PI parameter
P03.00，P03.01
The speed
characteristics of vector control can be adjusted
by setting the proportional coefficient and
integral time of speed regulator. Increasing
