Electrical loop D-axis proportional gain
F6.16
Electrical loop D-axis integral gain
F6.17
Electrical loop Q-axis proportional gain
F6.18
Electrical loop Q-axis integral gain
F6.19
Set asynchronous machines, synchronous machine vector control PI current loop parameters. When VC, if there is
instability like speed surge or current surge, the respective gain may be appropriately reduced to realize stability; at the
same time, increasing gain helps to improve motor dynamic response.
F6.25 Vector boost gain
F6.26 Vector boost filter time
F6.27 Vector slip compensation gain
F6.28 Vector slip compensation filter time
When the asynchronous machine VC without PG (F0.00 = 1), the controller automatically compensates for voltage and
frequency, [F6.25] and [F6.27], respectively voltage compensation gain and frequency compensation gain, the greater
the gain, the more the compensation, the stronger the low-band carrier energy; [F6.26] and [F6.27] respectively
compensation filter coefficients; when compensate instability occurs, appropriately increase filter time.
F6.31 MTPA gain
F6.32 MTPA filter time
MTPA function is optimizing the PMSM excitation strategies to achieve Max motor output / motor current; when the
permanent magnet motor D, Q-axis inductance difference is large, adjust [F6.31] can significantly change the motor
current under same load; adjust [F6.32] can improve the stability of the motor running.
F6.33-F6.35
PM demagnetization current limit
F6.36
PM weak feed forward gain
F6.37
PM weak magnetic proportional gain
F6.38
PM weak magnetic integral gain
F6.39
When permanent magnet synchronous motors operating in high-performance mode, magnetic weakening and speed
increasing can be implemented, the upper limit of magnetic currents is set by [F6.36], default 0 of [F6.36] is equivalent
to close weakening function; [F6.37-F6.39] sets weakening control adjustable parameters, when weakening instability
occurs in the process of weakening magnetic, adjust the set of parameters for commissioning.
Open loop start mode
F6.42
VC without PG synchronous machine has two startup modes: direct start and location detection start; in direct start
mode, a certain degree of reverse rotating of the motor would occur. For relatively high start reversing occasions,
position detection start can be selected to avoid start reversing, but it will bring start delay and noise
Stabilizer proportional gain
F6.45
Stabilizer proportional integral
F6.46
When selecting a permanent magnet motor VC without PG (F0.00 = 6), if there is a current or speed instability
fluctuation, adjust [F6.45] and [F6.46] to improve and eliminate.
