Step4
In case the straight ahead switch SW1 is mounted very close to the
straight ahead direction, 0-POS TEACHING is not required.
12.2.2 Stepper Motor with mechanical angle limitation
We assume the special adjustment AUX FUNCTION 11 together with the
adjustment PULSE IN 180 DEG are correctly set in their default value. Then no
quick set-up is required (otherwise see procedure 12.5 for the manual setting of
PULSE IN 180 DEG).
Only one procedure (0-POS TEACHING) is suggested for the quick set-up (in case
the straight ahead switch SW1 is mounted very close to the straight ahead
direction, 0-POS TEACHING is not required):
Step1
Set and save hardware setting 0-POS TEACHING to ON and recycle the
key.
Step2
After the initial alignment a warning BAD STEER 0-SET occurs. Release
the stepper motor and turn the traction moving. Roll-up and down the
adjustments STEER 0-POS DEG (see 13.3.3.7) to get the truck straight
travelling.
Step5
Save STEER 0-POS DEG and recycle the key to exit the BAD STEER 0-
SET warning.
12.3 Sectors vs. Cam position and switches configuration
The steered wheel revolution is divided into 4 sectors (quadrants).
Every sector has a length of 90 degrees.
The 90 degrees switch (SW2 connected to CNA#11) must be mounted exactly to
an angle being 90 degrees vs. the straight ahead switch (SW1 connected to
CNA#12). The admitted tolerance for the SW2 mounting arrangement is
(SW1+90deg) or (SW1 – 90deg) +/- 5degrees.
The cam instead must be 180 degrees long. The admitted tolerance for the cam
length is /- 20degrees.
There are mainly 4 mounting arrangements for the prox switches (see figure
12.3.1-1 and 12.3.2-1 below). Two cases are considered: ENC SPEED > 0 in CCW
or in CW direction.
