Do anybody have any idea on what sequence does ST Motor Profiler follow to measure inductance ? How accurate it is ?

Question asked by Ram Krishan Sharma on Jun 12, 2017

The motor profiler starts profiling starts to measure the motor parameters like R,L ,Kb and other mechanical parameters but every time i use the values are different from physical measurements  which gives me a confusion when to rely on Motor profiler and when not ?

I want to understand the Algorithm so that i can know where to use values measured by profiler and when to mesure using test setup.
