2200-02 SSI Protocol
[Unsigned8, rw]
It sets the SSI protocol used by the SSI encoder to arrange the absolute position
information. The SSI protocol can be the “LSB Right Aligned” protocol (00h) or
the “MSB Left Aligned” protocol (01h). For any information on the SSI protocol
please refer to the “User's manual” of the connected encoder.
Default = 00h
EXAMPLE
We need to connect the following rotary encoder:
MM36 12/8192 BB
.
MM36 encoder uses the 25-bit “LSB Right Aligned” protocol to arrange the
absolute position information. Thus you have to set the value 00h here. For
further information refer to the “User's manual”.
2200-03 Number of SSI clocks
[Unsigned8, rw]
It sets the number of SSI clocks required by the SSI encoder to send the
complete data word. The number of clocks depends on the encoder resolution
and the type of SSI protocol. The value has to be comprised between 1 and 32. If
you enter an out-of-range value, the number of clocks is forced to the default
value. For any information on the SSI clocks required please refer to the “User's
manual” of the connected encoder.
Default = 20h
NOTE
If the
2200-02 SSI Protocol
object is set to 01h = “MSB Left Aligned” protocol,
the
2200-03 Number of SSI clocks
must be equal to the number of bits of
the total physical resolution .
EXAMPLE
We need to connect the following rotary encoder:
AS58 13/BB
.
AS58 uses the 13-bit “LSB Right Aligned” protocol to arrange the absolute
position information as its overall resolution is

13 bits (13 bits). It always
requires 13 clocks (the length of the word is always 13 bits, regardless of the
max. number of information to provide). Thus you have to set 13 here. For
further information refer to the “User's manual” of the connected encoder.
EXAMPLE
We need to connect the following rotary encoder:
AM36 19/4096 BG
.
AM36 encoder implements the “MSB Left Aligned” protocol and requires 31
clocks (the length of the word is 31 bits). Thus you have to set 31 in this entry.
For further information refer to the encoder's “User's manual” of the connected
encoder.
