The above parameters apply only to the vector control mode. Below switching
frequency 1 (F5.02), speed loop PI parameters: F5.00 and F5.01. Above switching
frequency 2 (F5.05), speed loop PI parameters: F5.03 and F5.04. Between the two, PI
parameters are obtained by the linear changes of two sets of parameters, as shown
below:
By setting the proportional coefficient and integral time of speed regulator, you
can adjust the characteristics of speed loop dynamic response of vector control.
Increasing the proportional gain as well as decreasing integral time, which can
accelerate the speed loop dynamic response, but the too large proportional gain is or the
too small integration time easily cause system oscillation and too large overshoot. The
too small proportional gain also easily lead to the system steady-state oscillation, and
the speed static difference may exist.
Speed loop PI parameters are closely related to and the inertia of system, shall be
adjusted based on the default PI parameters especially for different load needs, in order
to meet the needs of a variety of occasions.

50% to 200% 100%
☆
Slip compensation coefficient is used to adjust the slip frequency of vector
control, improve the accuracy of system speed control, if the parameter is appropriately
adjusted, the speed static difference can be effectively suppressed.

Inverter in the running state, the parameters are shown by the F6.01 limit, that is, a
16 bit binary number, if one is 1, then the corresponding parameters can be run at the
time, through the SHIFT key to view. If the bit is 0, the corresponding parameter will
not be displayed. Set the function code F6.01, the binary number will be converted to
sixteen decimal, enter the function code.
Such as:
Choose to monitor load speed, the F6.01 should be set to fifteenth 1; choose to
monitor the AI1 voltage, the F6.01 should be set to ninth 1, and so on. The following
data is obtained by assuming that all relative positions are set to 1 at the request:
