DESCRIPTION: COMMUTATION ENCODER
The AMT 303 is a commutation
encoder with additional incremental
channels A, B, and Z. The encoder
output utilizes standard U,V,W
commutation signals with additional
quadrature A,B and Index signals
provided for speed control or
positioning operations. A SPI serial
bus allows for commutation settings
to be easily adjusted via a demo
board, or preconfigured and stored
for large production assembly for
various motor configurations.
FEATURES
