Example
“HM5816/16384/FB-xx”: multiturn encoder

Hardware counts per revolution = 65536 (2
16
)

Hardware number of turns = 16384 (2
14
)

Total hardware resolution = 1073741824 (2
30
)
Set parameters values:

Counts per revolution = 50000

Number of revolutions = 8000

Total resolution = 400000000
Hardware number of turns
=
16384
= 2.048
Number of revolutions 8000
It follows that, for 384 revolutions (16384 - 2 * 8000 = 384), the
encoder will work within the "Red Zone" limits.
NOTE

The “Red Zone” status is indicated by the green LED flashing
while the red LED is OFF (see the section “4.9 Diagnostic LEDs”
on page 12).

Within the limits of the “Red Zone”, the transmitted position is
coherent with setting resolution: it is calculated so that the last
position transmitted before zero position is
Total resolution -1.

Make attention using the values sent by the encoder while
working in “Red Zone”. When the encoder changes from normal
status to “Red Zone” status (and vice versa) a jump of position
occurs.
