Group P2 Vector Control Parameters
Group P2 is valid only for vector control. That is to say, when P0-01= 1, it is valid, and when P0-01=0, it is
invalid.
P2-00
Speed loop proportional gain 1
Factory default
30
Setting range
1 ~ 100
P2-01
Speed loop integration time 1
Factory default
0.50s
Setting range
0.01s ~ 10.00s
P2-02
Low switching frequency
Factory default
5.00Hz
Setting range
0.00 ~ P2-05
P2-03
Speed loop proportional gain 2
Factory default
20
Setting range
1 ~ 100
P2-04
Speed loop integration time 2
Factory default
1.00s
Setting range
0.01s ~ 10.00s
P2-05
High switching frequency
Factory default
10.00Hz
Setting range
P2-02 ~ P0-10 (maximum frequency)
P2-00 and P2-01 are PI adjustment parameters when the running frequency is lower than low switching
frequency (P2-02). P2-03 and P2-04 are PI adjustment parameters when the running frequency is higher
than high switching frequency (P2-05). PI parameter of frequency channel between low switching
frequency and high switching frequency is linear switching between two groups of PI parameters, as
shown in the figure below:
Figure 6-2 PI parameter diagram
The speed dynamic response characteristics of the vector control can be adjusted by setting the
proportional coefficient and integration time of the speed regulator.
Increasing the proportional gain or reducing the integration time can accelerate the dynamic response of
the speed loop. However, if the proportional gain is too large or the integration time is too short, it will cause
the oscillation of the system.
Recommended adjustment method:
