1 Time between successive SSI words (T
p
) (also called Dwell Time).
2 Roughly corresponds to the maximum time the SSI sensor can be expected to output a particular position value while in motion. To use
the 1738-SSI module with sensors that have faster position forming times, change the SSI Word Filter Control parameter from its
default value of 5 (max). Changing this parameter from its default value sacrifices electrical noise environment performance for sensor
data conversion speed.
3 Use this conductor category information for planning conductor routing as described in publication 1770-4.1, “Industrial Automation
Wiring and Grounding Guidelines.”
