Resolver adapter OPT-MF-201
The resolver adapter (OPT-MF-201) allows a motor with resolver feedback to be
connected to the MicroFlex e190. The MicroFlex e190 must be power-cycled after
con
necting the resolver adapter. The resolver adapter sends an absolute position to
the MicroFlex e190 at startup, so a
phase search is not required. In Mint WorkBench,
select a resolver motor in the Drive Setup Wizard. The wizard’s Feedback page will
show the feedback type as Resolver Adapter. The resolver adapter can be used in
conjunction with the encoder breakout (OPT-MF-200).
