Miscelaneous variables
kf
[lpf]
Synchronous filtering gain for measurements (lpf). The higher the value, the more "trust" is assigned to the value averaged during the last electrical revolution.
kr
[lpf]
Filtering gain for measurements (lpf). The higher the value, the more "trust" is assigned to the exponentially filtered value.
If a state variable's name ends with "f", it indicates that the presented reading has been filtered using the
kf
andkr
settings. Example:/driver/motor/curentqf

Vector control algorithm flags.
Bit | Name | Description |
---|---|---|
0 | reserved | |
1 | d-axis voltage is prioritized over the Q-axis voltage | |
2 | d-axis negative current only | |
3 | d-axis positive current only | |
4 | psi correction according to the D-Q inductances |
E.g. setting bits 2 and 3 together will turn off D-axis current control yielding to the frequency inverter mode.
A default value is zero. Other values are considerable for these use-cases: IPM motor with regeneration in field weakening. IPM motor with precision torque control and estimation. SynRM motor. Frequency inverter mode: driving an ACIM or a transformer.
