Figure 36: iC-MU with TTL ABZ and TTL BiSS (MA + SLO)
The iC-MU is forced to be operated with BiSS by PA0 with TTL lines of A, B, Z, BiSS(MA), BiSS(SLO), and
to GND.
5 V power supply.
The iC-MU SLI input can be forced to GND if the BiSS
communication is point-to-point.
With active Encoder Link State figure 36 shows the En-
coder Link State operation of the incremental encoder
The NERR LED signal is optional and incorporates a
sensor’s NERR signal and the iC-HF line driver error
status.
