Connecting an Encoder
RECOMMENDED ENCODERS
An optional encoder connects to the STAC6 using an HD15 male
connector. Add this connector referencing the diagram below. It is
not essential to connect the Z (index) channel.

Differential encoders are highly recommended over single-ended
types. They are far less sensitive to electrical interference and
provide problem free performance. Use of differential encoders
with the STAC6 enables the drive to detect a broken wire or bad
signal and display an alert.
If using single-ended encoders, connect to the A+ and B+ terminals
only. These terminals are internally biased to the proper voltage and
will provide the best performance results. Also, select the "single-
ended" box in the encoder dialog. Failure to do so will make the
drive function as if a broken wire has been encountered.
