Available to adjust the dynamic response performance of vector control speed cycle by
setting the proportion coefficient and integral time of speed regulator. The increase of
proportion gain and decrease of integral time both can accelerate the dynamic response of
speed cycle. But too big proportion gain and over short integral time both easily result to
system oscillation and excessive over adjustment. While too small proportion gain will also
cause static system oscillation and speed static error.
Speed cycle PI parameter has close relations with system inertia,and needs to be adjusted
based on default PI parameter for different load performances so as to meet the demands
of various occasions.
2 Vector Control Parameters
Parameters above are suitable for vector control mode only. When switching the frequency
lower than 1 (02-02), the speed cycle PI parameter is 02-00 and 02-01. When switching the
frequency higher than 2 (02-05), the speed cycle PI parameter is 02-03 and 02-04. When
switching the frequency from 1 (02-02) to 2 (02-05), the PI parameter is obtained from linear
variation of two groups of parameters as follows:
Speed cycle proportional gain 1
Setting range 0~100
02-00
Factory setting 30
Speed cycle integral time 1
Setting range 0.01~10.00s
02-01
Factory setting 0.50
Switch for lower point frequency
Setting range 0.00~02-05
02-02
Factory setting 5.00
Speed cycle proportional gain 2
Setting range 0~100
02-03
Factory setting 25
Speed cycle integral time 2
Setting range 0.01~10.00s
02-04 Factory setting 1.00
Switch for higher point frequency
Setting range 0.00~02-05
02-05 Factory setting 10.00
