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 and kr settings. Example: /driver/motor/curentqf

vcf [-]

Vector control algorithm flags.

Bit	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.

bcf [-]

BLDC control algorithm flags.

Bit	Name	Description
0	com_holdoff	sensorless startup configuration
1	stalloff	sensorless startup configuration
2	stallon	sensorless startup configuration
