Drive A1 Submenu
59
To set up ARB3:
1. Verify that the Pre Torque Src (C1) is set
to none so it does not affect the ARB
function.
2. ARB3 is enabled by setting ARB Select
(C1) to ARB3.
3. After enabling the function in ARB Select
(C1 Submenu), in most cases ARB3 will
work well with all related A1 Submenu
parameters at their default values. There
are only three parameters that may need
any adjustment by the user.
4. Parameters that should left at default are
ARB Deadband, ARB KP1, ARB KI1, and
ARB FFWD. It is rare where would need to
be adjusted.
a. The following are symptoms that may be
encountered after enabling ARB3 and
parameter adjustments that may be
attempted in the order listed.
i.
Vibration at start
– This applies if the
vibration only occurs only after
enabling ARB3. If the same vibration
occurs with ARB Select set to
DISABLED then there is an unrelated
cause that should be investigated and
corrected before enabling ARB3.
Try decreasing ARB Advance in
decrements of .05 sec. If vibration
is completely eliminated then
leave ARB Advance set to the
largest value which eliminates it
and disregard the next step. If no
improvement is achieved set ARB
Advance back to the default of
0.30 sec. and move on to the next
step. If some, but not complete
improvement is achieved, leave
ARB Advance set to the largest
value below which no further
improvement is observed and
move on to the next step.
If vibration is still present at start,
try decreasing ARB Decay in
decrements of 0.05 sec. If
vibration is completely eliminated
leave ARB Decay set to the
largest value which eliminates it. If
no improvement is achieved, set
ARB Decay back to the default of
0.20 sec and contact Technical
Support. If some, but not
complete improvement is
achieved, leave ARB Decay set to
the largest value below which no
further improvement is observed
contact Technical Support.
ii. Still some rollback at start
If rollback is still present at start,
try increasing ARB Advance in
increments of 0.05 sec. If rollback
is completely eliminated then
leave ARB Advance set to the
smallest value which eliminates it
and disregard the next step. If no
improvement is achieved set ARB
Advance back to the default of
0.30 sec. and move on to the next
step. If some, but not complete
improvement is achieved, leave
ARB Advance set to the smallest
value above which no further
improvement is observed and
move on to the next step.
If rollback is still present at start,
try increasing ARB Decay in
increments of 0.05 sec. If rollback
is completely eliminated then
leave ARB Decay set to the
smallest value which eliminates it.
If no improvement is achieved, set
ARB Decay back to the default of
0.20 sec and contact Technical
Support. If some, but not
complete improvement is
achieved, leave ARB Decay set to
the smallest value above which no
further improvement is observed
and contact Technical Support.
If either ARB Advance or ARB Decay has been
modified then ARB Timeout needs to be
set to a value which is 0.20
– 0.30 sec.
greater
than the sum
of ARB Advance and ARB
Decay.
