3.5.1 Input Lines
There are thirteen signal input lines; ten are standard and three
are user installable options. In multiple drive systems all input
lines will go to all drives but only the selected drive will
respond to these signals. A drive can be selected by a user
assigned jumper installation in the drive and by activating the
corresponding Drive Select input line. In multiple drive systems
using daisy chain connections, all input lines should be terminated
only at the last drive, while in star scheme connections, each
drive should be terminated properly. Input signal lines have the
following specifications:
A. Active or true = logical zero (O.OV to .4V)
B. Inactive or false = logical one (2.SV to 5.25V)
c. Input impedance = 150 ohm or 132 ohm for 220/330
termination.
