)
according to the structure explained above. Please note that you must enter
the value in the 21-bit long format (according to the encoder resolution), so
it is:
0000000000000000011110100001001000011 in binary notation. See the
following table:

4. Then, before saving the entered data, set the value “00” next to the
Preset
setting enable
register.
5. To save the new Preset value, you must use the

function
in the
Command
register (set “01” in the
Command
register).
6. To activate the new Preset value, you must use the Activate Preset
function in the
Command
register (set “02” in the
Command
register).
