AMM8A SSI & BiSS C-mode
Number of revolutions
[4E - 4F, ro]
These registers are meant to show the number of physical revolutions. For
information see the order code, the number of revolution can be up to 4,096
(AMM8Axx/
xxxxx
...).
You can read the number of bits used for the number of revolutions also at the
register 57
N° of bits used for multiturn resolution
.
Number of revolutions registers structure:
Register 4E 4F
MSB LSB
2 15 … 2 8 2 7 … 2 0
Default: see the order code (AMM8Axx/ xxxxx ...)
For example: 10 00h (=4,096 revolutions)
Preset
[50 … 54, rw]
WARNING
You are allowed to enter a value next to the Preset registers only if the Enable
preset bit in the Configuration register is set to ”1”.
These registers allow the operator to set the Preset value. The Preset function is
meant to assign a desired value to a physical position of the encoder. The
chosen physical position (i.e. the transmitted position value) will get the value
set next to these registers and all the previous and following positions will get a
value according to it. For instance, this can be useful for getting the zero point
of the encoder and the zero point of the application to match. The preset value
will be set for the position of the encoder in the moment when the command is
sent through the
Save and activate Preset
function of the
Command
register
(or through the Zero setting / Preset input signal, see the “5.4 Zero setting /
Preset input” section on page 33).
After having entered a value next to the
Preset
registers you can either save it
without activating the preset function or both save and activate it at the same
time.
Use the
Save parameters on EEPROM
function (set “01” in the
Command
register) to save the new Preset value without activating it.
Use the
Save and activate Preset
function (set “02” in the
Command
register)
to both save and activate the new Preset value.
The Preset value you are allowed to enter must be less than or equal to
(
Information per revolution * Number of revolutions ) - 1.
Default = 00 00 00 00 00h
Min. value: 00 00 00 00 00h
Max. value: 03 FF FF FF FFh
