Amplifier - PAF (Pole-Angle Finder) Dynamic Variables

ID Label Type #Val Min Max Attr Description

12700

Running count of # of PAF twangs

Int8

 

 

 

RO

Running count of # of twangs invoked during the PAF operation.

12701

PAF internal state

Int8

 

 

 

RO

State value for the PAF operation.

12702

PAF twang angle adjustment, degrees

Flt32

 

 

 

RO

The twang angle adjustment associated with the twang "zoom-in" search algorithm.

12703

PAF twang angle, degrees

Flt32

 

 

 

RO

Actual twang angle used during the twang search.

12704

PAF commutation reference position, mcnt

Flt32

 

 

 

RO

The final converged motor commutation position, or angle.

12705

PAF commutation reference angle, degrees

Flt32

 

 

 

RO

12706

PAF position delta of 1st twang, mcnt

Flt32

 

 

 

RO

Position delta during the PAF twang search process. Each search step of the PAF involves two twangs at different angles. The signs of the position deltas are checked. A sign change indicates a potential of a pole position, which causes the search algorithm to "zoom-in", and therefore, converge on the pole position.

12707

PAF position delta of 2nd twang, mcnt

Flt32

 

 

 

RO
