DESCRIPTION
Normalized percentage of the throttle input (pin 16 basis).
Note, this monitor variable appears in the System Monitor »
Command Inputs » menu.
Throttle request to the slew rate block of the motor control.
See Figure 22, Throttle Signal Processing.
Note:
Throttle_Command = 0 is Neutral,
Throttle_Command = +1 is zero throttle with fwd direction selected,
Throttle_Command = –1 is zero throttle with rev direction selected.
Multiplies the throttle signal, which is useful in VCL
throttle processing.
See Figure 22, Throttle Signal Processing.
Mapped throttle request.
See Figure 22, Throttle Signal Processing.
Configures how throttle direction is determined.
0. Fwd/Rev Switch. Requires a dedicated forward or reverse
input to turn the motor in the assigned direction. Asserting both
inputs at the same time results in a HPD Sequencing fault.
1. Based on the throttle mapping (Wig Wag). Here, the neutral point
must be set up somewhere in the center of the throttle throw,
with increasing voltage beyond this point providing increasing
forward command and voltages below this point providing
increasing reverse command. Wigwag throttles are only
applicable to 0–5V voltage and 3-wire potentiometer throttles.
Defines the 2- or 3-wire wiper or the voltage-throttle percentage
at the minimum-throttle threshold for the forward direction
(positive motor rpm). Increasing this parameter will increase the
neutral range (deadband). 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. See Figure 21, Throttle
Adjustments Diagram, below.
Defines the 2- or 3-wire wiper or voltage-throttle percentage
required to produce 100% controller output. Decreasing this
parameter value reduces the voltage necessary to produce
full-throttle controller output. This parameter accommodates
reduced-range throttle assemblies.
See Figure 21, Throttle Adjustments Diagram, below.
Modifies the vehicle's response to the throttle input. Setting this
parameter to 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. See Figure 21, Throttle Adjustments Diagram, below.
The map value is the percentage of controller output at half
throttle [(Min Input + Max Input)/2].
The same as the Forward Min Input parameter counterpart and
applies when throttle direction is reversed (negative motor rpm).
See Figure 21, Throttle Adjustments Diagram, below.
The same as the Forward Max Input parameter counterpart and
applies when throttle direction is reversed (negative motor rpm).
See Figure 21, Throttle Adjustments Diagram, below.
