I would like to know the physical concept of a specific item.

[hsg.1440]

Currently using ST MOTOR WORKBENCH 5.4.8.

 

1. LOOK question1.jpg

   About the numbers in the square area in the picture below
- It appears to be a converted number rather than the flowing current value. I would like to know the exact meaning of this number.
- For example, if you get 10000, you can actually interpret it as 4A. Like this

 

2. LOOK question2.jpg

This is the speed measurement part. We are currently using the sensorless (Observer + PLL) method.
1) I am curious about the exact physical meaning of Observer's G1 and G2 in the black square.
2) I would like to know what actual changes occur when the P/I value of the PLL in the red square changes.

thanks.
