The function code can be used to adjust the
power display value of motor 1. However, it does
not affect the control performance of the 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.

Description
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:
