now, if you need you can enter the Preset value next to the
object and then set it in the desired position; see on page
•
save the new setting values (
page 49).
NOTE
object (see on page 60) is set to “0”
= disabled, the position value read by the encoder can be processed according
to needs, so the user can scale the value, set a preset, and change the counting
direction. On the contrary, if the
object (see on page 60) is set
to “1” = enabled, the information from the encoder is transmitted “as it is” and
not processed in any way. The preset, scaling and counting direction functions
-even if set and enabled- are ignored; also the output code setting is ignored. If,
for example, the user sets a preset while the bypass mode is enabled, the value is
accepted, but not activated. As soon as the bypass mode is disabled, the preset,
scaling and counting direction functions -if set and enabled- become active and
the
will be accordingly.
EXAMPLE 1
We need to connect the
MM36 12/8192 BB
rotary encoder.
The main features of the rotary encoder are:
Singleturn Resolution:
12 bits = 4,096 cpr
(“12”, see the order code in the
product datasheet).
Multiturn Resolution:
13 bits = 8,192 rev.
(“8192”, see the order code in the
product datasheet).
Total resolution =
25 bits
= 4,096 x 8,192 = 33 554 432
Output code:
Binary code
(“BB”, see the order code in the product datasheet).
SSI protocol:
25-bit “LSB Right Aligned” protocol
(see the User's manual).
= 00h (= Binary code)
= 00h (= 25-bit “LSB Right Aligned” protocol)
= 19h (= 25 dec)
2200-04 Physical Singleturn Resolution [bits]
= 0Ch (= 12 bits = 4,096 cpr)
2200-05 Physical Multiturn Resolution [bits]
= 0Dh (= 13 bits = 8,192 rev.)
6502-00 Number of distinguishable
objects are automatically set accordingly and used to arrange the
position information
