6.2.9 F08: Motor Vector Control Speed-loop Parameters
Ref. Code Function Description Setting Range [Default]
F08.00 Low speed ASR Kp 1 - 9999 [500]
F08.01 Low speed ASR KI 0 - 9999 [500]
F08.02 High speed ASR Kp 1 - 9999 [500]
F08.03 High speed ASR KI 0 - 9999 [500]
F08.04 ASR PI swithcing frequency 1 0.00 - 50.00 [10.00Hz]
F08.05 ASR PI swithcing frequency 2 0.00 - 50.00 [15.00Hz]
F08.00 - F08.05 and F08.07 confirm the PID parameters of ASR. The structure of ASR is shown in figure:
As the right figure:
• When HD3L operates within 0 - F08.04, the PI parameters of
vector control are F08.00 and F08.01;
• When HD3L operates above F08.05, the PI parameters of
vector control are F08.02 and F08.03;
• When HD3L operates within F08.04 - F08.05, P is the linear
interpolation between F08.00 and F08.02, while I is the
linear interpolation between F08.01 and F08.03.
• The system response can be expedited through increasing the ASR KP (F08.00, F08.02), but oscillation
may occur if the value of KP is too high.
• The system response can be expedited through increasing the ASR KI (F08.01, F08.03), but oscillation and
high overshoot happen easily if the value of KI is too high.
• If F08.01 / F08.03 = 0 and the integral function is unused, the speed-loop works only as a proportional
regulator.
• Generally, adjust the KP firstly to the max. on condition that the system does not vibrate, and then adjust
the KI to shorten the response time without overshoot.
• To shorten dynamic response time during lowe frequency running, increase KP and KI.
F08.06 ASR integral limitation 0.0 - 200.0 (F07.02) [180.0%]
It is used to limit the max. value of the vector control speed-loop integral.
F08.07 ASR differential time 0.000 - 1.000 [0.000s]
Defines the vector control speed-loop differential time.
• Generally, it doesn’t need to set F08.07 except for expediting the dynamic response.
• F08.07 = 0, there is no speed-loop differential.
F08.08 ASR output filter time 0.000 - 1.000 [0.008s]
It is used to filter the output of ASR regulator.
• F08.08 = 0, the speed-loop filter is unused.
