70A 90A
Throttle Map 20% 50%
The throttle map parameter adjusts the static throttle map. The
parameter setting corresponds to the throttle command at
half throttle.
A setting of 50% provides linear response. Values below 50%
reduce the throttle command at low throttle positions, provid-
ing enhanced slow speed maneuverability. Values above
50% give the vehicle a faster, more responsive feel at low
throttle positions.
Tremor Suppression 50% 50%
This parameter can be used to limit the controller’s response
to sharp throttle movements, such as movements resulting
from hand tremors.
Larger values will provide a steadier ride, but they also result in
more sluggish response to throttle request. There is thus a
trade-off between crispness of response (low Tremor Sup-
pression settings) and steady speed in the presence of trem-
ors (high settings).
Calibration OFF OFF
Wigwag and unipolar throttle pots should be centered. Setting
this parameter to On inhibits driving and puts the controller
into throttle autocalibration mode.
Setting the parameter Off returns the controller to normal oper-
ation.
CURRENT MENU
Main Current Limit 70A 90A
Sets the maximum current the controller will supply to the
motor during normal driving. By limiting the current supplied,
this parameter can be used to protect the motor from poten-
tially damaging currents or to reduce the maximum torque
applied to the drive system.
Braking Current Limit 70A 90A
Sets the maximum current the controller will supply to the
motor during braking. By limiting the current supplied, this
parameter can be used to protect the motor from potentially
damaging currents or to reduce the maximum braking torque
applied to the drive system.
Boost Current 80A 90A
Boost current gives a brief boost of current that greatly
improves performance with transient loads, such as starting
on a hill, crossing a threshold, climbing obstacles, etc. When
the controller recognizes that the motor needs more current
to respond to a drive request, it provides a current boost of a
set amount for a set time.
The Boost Current parameter defines the motor current limit
during
the boost period
Boost Time 5.0 sec. 0.0 sec.
This parameter sets the maximum time that the boost current is
