e) The automatic centering request must have an NPN open collector output (see fig.
6.1.5.2). So it should assume the model of an open or closed switch with respect to
GND. External pull-up is not required. The automatic centering request may be level
or edge triggered depending on the AUT INP ACTIVE setting (see 10.7.7).
An edge is detected if the level before or after the edge remains for at least
30msec.
f)
Pin #18 of CNA connector provides 0 to 4.5Vdc output to control the steering angle
indicator gauge Leds. Pin # 8 of CNA connector provides negative to the steering
indicator.
g) Pin # 12 of CNA connector (centering acknowledgment) provides a max 2Amps
NPN open collector driver normally GND connected that opens when an automatic
centering operation is finished.
h) The CAN connections are provided on the Pin #3 and Pin#4 CNA connector for the
High reference and on Pin #13 and Pin #14 for the Low reference. They are two
because our CAN should be externally loaded with a 120 ohms resistance to termi-
nate the transmission line.
i)
The Eps_ac provides an encoder interface. It was foreseen for special applications
like accurate speed control or safety improvement. Normally it's not required. The
encoder channels are connected on Pin #16 and Pin #17 of connector CNA. The
encoder supply is provided through the Pin #6 of connector CNA (choose the supply
you want through the jumper J8-see 5) and a Gnd reference on the Pin #7 of
connector CNA (see fig. 6.1.5.3).
