Group 92 RESOLVER CONF
Resolver configuration; used when parameter 90.01 ENCODER 1 SEL / 90.02
ENCODER 2 SEL is set to (5) FEN-21 RES .
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
16.07 PARAM SAVE . The new settings will take effect when
the drive is powered up again, or after re-configuration is forced by parameter 90.10
ENC PAR REFRESH .
Resolver autotuning is performed automatically whenever the resolver input is
activated after changes to parameters
92.02 EXC SIGNAL AMPL or 92.03 EXC
SIGNAL FREQ . Autotuning must be forced after any changes in the resolver cable
connection. This can be done by setting either 92.02 EXC SIGNAL AMPL or 92.03
EXC SIGNAL FREQ to its already existing value, and then setting parameter 90.10
ENC PAR REFRESH to 1.
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
99.13 IDRUN MODE and section Autophasing
on page 37 .
