PARAMETER RANGE DESCRIPTION
Throttle Type 0 – 9 The 1204M/05M/09M/21M controllers accept a variety of throttle inputs. The
Throttle Type parameter can be programmed as follows:
0 2-wire potentiometer, 0–5k
Ω input
1 2-wire potentiometer, 5k
Ω–0 input
2 single-ended 0–5V input
3 2-wire potentiometer, 4.6k
Ω–0 input
4 2-wire potentiometer, 5.5k
Ω–0 input
5 2-wire potentiometer, 1k
Ω–0 input
6 ITS input
7 6.3–10.6 V input
8 6–12 V input
9 single-ended 3-wire potentiometer, 0–5k
Ω input.
Throttle Deadband 4 – 90 % The Throttle Deadband parameter defines the neutral deadband as a percent
-
age of the full throttle range. Increasing the Throttle Deadband setting will
increase the neutral range. This parameter is especially useful with throttle
assemblies that do not reliably return to a well-defined neutral point, because
it allows the deadband to be defined wide enough to ensure that the controller
goes into neutral when the throttle mechanism is released.
Throttle Max 10 –100 % The Throttle Max parameter defines the percentage of throttle movement at
which 100% output is requested. Decreasing the Throttle Max setting reduces
the full stroke necessary to produce full controller output. This parameter al
-
lows reduced-range throttle assemblies to be accommodated.
Throttle Map 20 – 80 % The Throttle Map parameter modifies the vehicle’s response to the throttle
input. Setting Throttle Map at 50% provides a linear output response to throttle
position. Values below 50% reduce the controller output at low throttle settings,
providing enhanced slow speed maneuverability. Values above 50% give the
vehicle a faster, more responsive feel at low throttle settings.
The Throttle Map value is the controller output at half throttle, as a
percentage of the Max Speed. Half throttle is the midpoint of the throttle’s active
range, which is the range from zero output (at the Deadband setting) to 100%
output (at the Throttle Max setting).
