Figure 37: iC-LNB with TTL ABZ and TTL SPI in Encoder Link State
The iC-LNB is configured by the sensor’s microcon-
troller via SPI where iC-LNB is the SPI slave and the
microcontroller is the SPI master.
With active Encoder Link State figure 37 shows the
Encoder Link State operation of the incremental en-
coder with TTL lines of A, B, Z, SPI(CLK), SPI(MISO),
SPI(MISO), and 5 V power supply.
The microcontroller and its flash ROM is configured
and accessed by an additional 3 wire capable SPI
communication where microcontroller is the SPI slave
and the external host is the SPI master.
The NERR signal is optionally available and incorpo-
rates a sensor’s NERR signal and the iC-HF line driver
error status.
