Ch1: SSI(2) - Cyclical SSI
The software versions required to run the SSI encoder interface are the standard
software versions for the ServoOne and ServoOnejunior.

SSI (Synchronous Serial Interface) is a digital encoder interface that is supported by
a large number of manufacturers. It is not standardized, meaning that manufacturers
are free to support the interface as they like. The pseudo-standard described below
has however been established for motor feedback interfaces. KEBA supports this
version first and foremost.
The following table lists the parameters for cyclical SSI operation on encoder
channel Ch 1. It also points out possible differences between the use of the SSI
interface with the “cyclical” method and “one-time reading” method when using
SinCos encoders with an SSI absolute value interface.
SSI encoder basics and requirements
The SSI interface on the ServoOne has been designed as an actual motor feedback
interface. Accordingly, the connected SSI encoder must meet the following criteria:
