Issue A
Sensing and Control
NOTICE
Ensure the resolver is properly installed. Improper installation
may result in greater resolver errors, especially with the smaller
resolvers.
Ensure the following:
• Useaflexiblecoupling(nobacklash)toattachtheresolvershaft
totheapplicationshaft.Flexiblecouplingspreventexcessive
sideloadingoftheresolverwhichreducebearinglife,and
possiblycausegreatererror.
