Figure 35: iC-HF with BiSS + A/B/Z using only 8 lines
The left side of figure 35 shows the standard operation
of the incremental encoder with differential lines of
A+/A-, B+/B-, Z+/Z-, and 5 V power supply. With active
Encoder Link State figure 35 on the right side showing
the Encoder Link State operation of the incremental
encoder with TTL lines of A, B, Z, BiSS(MA), BiSS(SLI),
BiSS(SLO), and 5 V power supply.
The NERR signal is optional and incorporates a sen-
sor’s NERR signal and the iC-HF line driver error status.
The SLI signal is only required if the sensor needs to
be operated in a BiSS bus structure or if MO control is
required.
