Overview
AEC Description The AEC is an absolute encoder converter. It receives the absolute
position sent by the SSI transducer and changes it to an incremental
quadrature signal that the 1394 GMC System module and the S Class
Compact motion controller can use.
The AEC is designed to accept outputs from absolute encoders, linear
displacement transducers, or any other measuring device, which
transmits its measured values over an SSI. Several devices are
supported with various combinations of counts per turn and number
of turns. These are defined in the Setup chapter of this manual.
Parallel output devices are not supported.
The AEC provides two independent channels from absolute to
incremental quadrature conversion. The resolution of each channel is
set via rotary switches and each one can operate with a transducer
using a different supply voltage. (Although the supply voltages may
be different, they are not isolated. The grounds must be of equal
potential.) Each channel can be individually strobed to obtain new
absolute or incremental position information.
