do the R2 and R4 resistor limit current to protect the motor or the LMD? I thought it was to protect the LMD but if thats the case why not set it at somewhere above 6.6k and leav it at that?
The reason I ask is I am sizing mine for a 2.8A motor which comes out to
20000/2.8 = 7143 Do I set it for a 7.15k resistor or should I provide a buffer and set it higher?
Any help would be appreciated.
