11) AUXILIARY TIME
This parameter defines the time, after the steer handle is released and the travel
demand deactivated, for which the stand still torque is applied.
-
LEVEL 0: No stand still torque.
- LEVEL 1: Brief application of the stand still torque (about 6 secs).
- LEVEL 9: Long application of the stand still torque (about 90 secs).
Intermediate levels are for proportionally increasing auxiliary time. The stand still
torque reduces with a ramp from the ANTIROLLBACK value down to zero with a
delay specified with this setting.
12) ANTIROLLBACK
This parameter adjusts the standstill torque after the steer handle is released
and the travel demand deactivated.
It is in percentage of the maximum current.
Injecting a continuous current in the motor generates the stand still torque. It is
useful (together with the CREEP SPEED parameter, see 12.4.4.3) to neutralize
the recall torque generated by the elastic tyre on the steered wheel.
13) 1ST ANGLE COARSE
Depending on the configuration, this parameter has different meaning.
RTC version with feedback pot:
This parameter regulates in coarse steps the maximum steered wheel angle in
the direction where FEEDBACK ENC is higher than 2.5 V. It is a scaling factor
between the SET POINT POT reading and the FEEDBACK ENC reading.
By increasing this parameter, the maximum steered wheel angle increases too.
The maximum angle in RTC should be regulated in feedforward way by properly
adjusting the angle settings.
Stepper Motor version with toggle switches:
This parameter regulates in coarse steps the maximum steered wheel angle in
the direction where FEEDBACK ENC is higher than 2.5 V. It limits the angle
measured with the reading WHEEL ANGLE in the following range:
-
LEVEL 0: Angle is limited to a WHEEL ANGLE is +80 degrees.
- LEVEL 1: Angle is limited to a WHEEL ANGLE is +84 degrees.
- LEVEL 9: Angle is limited to a WHELL ANGLE is +118 degrees.
Each step has a weight of 3.8 degrees.
When 1ST ANGLE COARSE and 2ND ANGLE COARSE are both to Level 9,
the angle limitation is inhibited.
14) 1ST ANGLE FINE
(RTC version only). This parameter regulates in fine steps the maximum steered
wheel angle in the direction where FEEDBACK ENC is higher than 2.5 V. It is
used in closed loop application only (RTC) and it is a scaling factor between the
SET POINT POT reading and the FEEDBACK ENC reading.
By increasing this parameter, the maximum steered wheel angle increases too.
15) 2ND ANGLE COARSE
Depending on the configuration, this parameter has different meaning.
RTC version with feedback pot:
This parameter regulates in coarse steps the maximum steered wheel angle in
the direction where FEEDBACK ENC is lower than 2.5 V. It is a scaling factor
between the SET POINT POT reading and the FEEDBACK ENC reading.
