Interfaces

The following chapters give detailed information about the connections and interfaces.
6.2.1 Interface SSI (option SB0 and SG0)
If the clock is not interrupted for the time Tm-T/2 (output of further 25 periods), the shift register clocks once
again the same data value (error recognition in evaluation).
Some encoders contain a Power Failure Bit (PFB):
With EMAX-RO the PFB is always „LOW".
