Short overview of the relevant parameters:
How to parameterise the SSI encoder:
1. As encoder type (
), select "4: Absolute value encoder (SSI)".
) for SSI communication.
• For SSI protocols, the permissible baud rate is reduced if the cable length is increased. A
safe bit rate must be set, depending on the length of the used encoder cable and the
electromagnetic interference level.
3. Go to
and set the distribution of the SSI data word according to the SSI
encoder used (see the following subchapter).
4. If an SSI encoder with Gray coding is used:
Add the selection "1: Gray code" for a data conversion from Gray to binary code in
• In the Lenze setting, "0: Binary code", conversion is not performed, i.e. an SSI encoder
with binary coding is expected.
