EXAMPLE 5
Let's suppose we need to program the following encoder:
“AMT58” 25-bit multiturn encoder.

Hardware counts per revolution = 13 bits/rev. (8192 cpr)

Hardware number of revolutions = 12 bits (4096 rev.)

Hardware total resolution = 25 bits (8192

4096=33554432)
We want to set: 360 counts per revolution and 4000 revolutions.
Neither 360 nor 4000 is a power of 2.
Thus we will set 360 next to the Counts per revolution item.
The Total resolution value will be: 360 (cpr)

4000 (rev.) = 1440000
10
= 0x15F900
The value to be set in the Total resolution items will be as follows:
Total resolution (high) Total resolution (low) Value
0015 F900 hexadecimal
21 63744 decimal
After having set new parameter values, click the OK button to
close the Properties – DP Slave window and then the
Download button (see icon on the left) in the toolbar of the
HW Config window to download the set parameters.
