Example
Multiturn encoder AMT58 with connection cap.
The hardware resolution is:

Hardware counts per revolution = 4096 (2
12
)

Hardware number of revolutions = 4096 (2
12
)

Hardware total resolution = 16777216 (2
24
)
We need to set the following custom resolution: 2048 counts per
revolution

1024 revolutions.
To do this proceed as follows:

Enable Class 2 functionality :
byte 10=0A hex (bit 1=bit 3= “1”)

Enable Scaling function :

Counts per revolution = 2048: bytes 11-12 = 0800 hex

= 2048

1024 = 2097152: bytes 13 … 16 = 0020 0000 hex.
NOTE
When new values are set next to the
Counts per revolution and/or
Total resolution items, also a new Preset value is required. It has to
comply with the new resolution you have set.
WARNING
Please note that the in Step 7 the
Total resolution value has to be
split into two separate fields, namely Total resolution (high) and Total
resolution (low). This value in fact must be entered in two words.
Please refer to the examples on page 19 to understand how the Total
resolution value has to be divided into two parts: a high part and a
low part.
The following values are allowed:
multiturn model
Total resolution (high): default
= 256 (min. = 0, max. = 512)
Total resolution (low): default = 0 (min. = 0, max. = 65535)
