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).
SET STEER 0-POS may be rolled up or down in 5 mV steps. 2492mV is the default
value.
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.
This adjustment is used to acquire the encoder counting corresponding to a partial
steered wheel revolution (about a half) occurring between two falling edges of the
straight ahead sensor : the first falling edge occurs on incidence of the first iron plate
limit; the second falling edge occurs on incidence of the second iron plate limit .It is
an important setting for applications without steered wheel angle limitation.
Procedure for SET ENC AT 180 consists of collecting the encoder counting
corresponding to that half steered wheel revolution on the tester reading ENC
COUNT AT 180. To do that two ways are available: autoteaching and manual
teaching.
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.
This adjustment is used to acquire the encoder counting corresponding to a full
steered wheel revolution. It is an important setting especially for applications without
steered wheel angle limitation. Procedure for SET ENC AT 360 consists of collecting
the encoder counting corresponding to a full steered wheel revolution on the tester
reading ENC COUNT AT 360. To do that three ways are available: autoteaching,
manual teaching and SET ENC AT 360 manual setting.
Autoteaching procedure automatically saves the new ENC COUNT AT 360 on SET
ENC AT 360; manual teaching asks the ENC COUNT AT 360 being manually
saved on SET ENC AT 360; SET ENC AT 360 manual setting consists of writing
directly the SET ENC AT 360 value in EEPROM .
