3-6 Communicate with Your Module

Gray to Binary Conversion No/Yes Convert data from Gray to

binary

SSI Word Delay Time (t

)16µs… to 64ms (64µs) Delay time between

successive SSI data words

SSI Word Filter Control Off, Low, Med, High, Max Corresponds to the number

of successive equal SSI data

words that must be received

by the module in order to

update the real-time present

SSI data word.

Standardization Off/On Off = Use entire data word

length specified by Data

Word Length parameter.

On = Data is right-shifted

the number of bits specified

in the Trailing Bits

parameter.

Trailing Bits 0… 16

Sensor Resolution 1… 65535 Total number of

positions/revolution for a

rotary encoder,

positions/stroke for a linear

displacement transducer, or

maximum counts for

distance measurement.

Sensor Cycles 1… 65535 Total number of revolutions

for a rotary encoder, strokes

for a linear displacement
