ARB MODE
Selects between 3 possible Anti-Rollback
operating modes.
"0" to disable all Anti-Rollback features.
Only E-Reg will be engaged
"1" to enable Anti-Rollback when the
drive is started.
"2" to enable Anti-Rollback when starting
the drive and when the velocity again
comes to a stop at the next landing.For
more information, see Anti-Rollback on
page 125.
none 0 0 - 2
Y Y
ARB
BANDWIDTH
Determines the gain of the velocity and
position regulator when ARB is ON. This
is the unity gain crossover frequency in
Radians/sec. Increasing this setting will
cause the position loop to respond faster
with less accumulated position error.
For more information, see Anti-Rollback
on page 125.
RAD 6.00 1.00 – 15.00
Y Y
ARB DAMPING
Adjusts damping of the position regulator
when ARB is ON. Increasing this setting
will cause a smoother but slower
recovery of position error. Reducing this
setting will let ARB recover a position
error more quickly and abruptly.
For more information, see Anti-Rollback
on page 125.
none 2.00 0.01 – 20.00
Y Y
ARB SPEED
THRESHOLD
Determines the reference speed where
ARB will be turned OFF and E-Reg will
be engaged when the drive is started, if
ARB mode is set to 1 or 2. This setting
should be as low as possible to prevent
regulator transfer bumps when starting,
but it must be set high enough to remain
engaged during re-leveling or to ignore a
small analog zero reference offset when
using an external analog signal
reference. In percent of rated speed
For more information, see Anti-Rollback
on page 125.

NOTCH FILTER
FRQ
(Notch Filter Frequency)
Determines the
notch filter center frequency. For more
information, see NOTCH FILTER FRQ on
page 49.
Hz 20 5 – 60
Y Y
NOTCH FILT
DEPTH
(Notch Filter Depth) Determines notch
filter maximum attenuation.
Note: A filter depth setting of zero
(NOTCH FILT DEPTH (A1) = 0) removes
the filter.
% 0 0 – 100
Y Y
STNDBY FLD
TIME
(Standby Field Delay Time)
Determines
the time the drive will continue to supply
Full Field current after stopping and
turning motor armature current control
OFF. Motor field current will drop to
standby amps after this time delay.
