Application Setup
Recorded data is expressed in internal drive unit (analog-to-digital converter counts).
A typical resolver record might look like the figure below.
Converting to physical value
The recorded data is expressed in internal drive unit and needs to be converted to physical
unit; i.e. drive input voltage.
Since the physical sine and cosine signal scales of the sine encoder and resolver are different,
the following equation is used to convert the recorded data:
Sine encoder: input voltage
Resolver: input voltage
Check the data diagram
Recorded data can be converted in the ServoStudio2 "Range" screen.
