ABB ACL30 User Manual

172 Program features
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 90.06
ENC PAR REFRESH to Configure.
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 also parameter group 90 ENC MODULE SEL on page 268, and FEN-21 resolver
interface user’s manual (3AFE68784859 [English]).
Settings
 Pulse encoder configuration
Pulse encoder configuration can be used for TTL/HTL input and TTL output
configuration.
Parameters 93.01 ENC PULSE NR…93.06 ENC OSC LIM can be used when a
TTL/HTL encoder is used as encoder (see parameter 90.01 ENCODER SEL).
Typically, only parameter 93.01 needs to be set for TTL/HTL encoders.
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 16.05 PARAM SAVE. The new settings will take effect when
the drive is powered up again, or after re-configuration is forced by parameter 90.06
ENC PAR REFRESH.
See also parameter group 90 ENC MODULE SEL on page 268, and the appropriate
encoder extension module manual.
