36 Operation

Position at Start-up

In locked mode, the AEC sends incremental position after receiving

incremental strobe pulses. The AEC, when configured for free-running

mode for controlling hardware other than the Compact or 1394, sends

the incremental position at start-up. In this mode, the AEC behaves

like an incremental encoder. Neither mode requires an absolute

update to begin transmitting positional information.
