Resolver configuration; used when parameter
ENCODER 2 SEL
The optional FEN-21 Resolver Interface module is compatible with resolvers which
are excited by sinusoidal voltage (to the rotor winding) and which generate sine and
cosine signals proportional to the rotor angle (to stator windings).
Note: Configuration data is written into the logic registers of the adapter once after
the power-up. If parameter values are changed, save values into the permanent
memory by parameter
the drive is powered up again, or after re-configuration is forced by parameter
ENC PAR
Resolver autotuning is performed automatically whenever the resolver input is
activated after changes to parameters

connection. This can be done by setting either
EXC SIGNAL FREQ
ENC PAR REFRESH
If the resolver (or absolute encoder) is used for feedback from a permanent magnet
motor, an Autophasing ID run should be performed after replacement or any
parameter changes. See parameter
on page 39.
