Autoteaching procedure automatically saves the new ENC COUNT AT 180 on
SET ENC AT 180; manual teaching procedures asks the ENC COUNT AT 180
being manually saved on SET ENC AT 180.
17) ZERO SP POT
(Twin Pot version only). This adjustment is used to self-acquire (see 10.1.3 and
10.2.3) the voltages on the twin potentiometers when the steer handle is
released in its straight ahead position. Just push the enter button with a
released steer handle to record the new ZERO SP POT value.
18) SET STEER 0-POS
It must be set to the FEEDBACK ENC value corresponding to a perfectly
straight-ahead steered wheel inside the first and fourth quadrant (i.e. it must be
set to the value of FEEDBACK ENC for a steered wheel that is straight ahead
around the null WHEEL ANGLE position). The steered wheel will be positioned
to SET STEER 0-POS either when an AUTC is demanded (in case the steered
wheel angle is electrically limited or in case the steered wheel is the first and
fourth quadrant) or in the Twin pot applications when the twin pot assumes the
ZERO SP POT value.
For a twin pot application, correct setting is favourite by exploiting the TILLER
DEAD ZONE option (see 11.4.1.8).
SET STEER 0-POS may be rolled up or down in 5 mV steps. 2500V is the
default value.
19) SET STEER 180
It must be set to the FEEDBACK ENC value corresponding to a perfectly
straight-ahead steered wheel inside the second and third quadrant (i.e. it must
be set to the value of FEEDBACK ENC for a steered wheel that is straight
ahead around the 180 degrees WHEEL ANGLE position). The steered wheel
will be positioned to SET STEER 180 when an AUTC is demanded (in the
second and third quadrant and for any application without electrical angle
limitation).
SET STEER 180 may be rolled up or down in 5 mV steps. 0mV is the default
value.
