Other Parts Discussed in Thread: MOTORWARE
Hello,
We have a custom design based on the TMS320F28054M that runs one type of 3 phase induction motor just fine. The engineer that designed and implemented this setup is no longer with our company.
We are now trying to run different types of 3 phase induction motors on this design, and we run in to issues with motor identification. Values returned makes little sense.
The design uses one LEM HXS 20-NP per phase for current measurements.This gives us a theoretical measurement range of approx -80A to +80A. 160A/4095=0.04A resolution in theory.
Our question is: is this resolution sufficient for the internal algorithms of the processor to work correctly or do we need to adjust the design?
Are the limits documented anywhere?
Br,
Øystein Andreassen
