PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Reverse Map Shape
Reverse_Map
0x3359 0x00
0 – 100 %
0 – 32767
35 % The same as the Forward Map Shape parameter counterpart and
applies when throttle direction is reversed (negative motor rpm).
See Figure 10, Throttle Adjustments Diagram, below.
Throttle Filter
Throttle_Filter
0x335E 0x00
0.5 – 125.0 Hz
131 – 32767
10.0 Hz Sets the low-pass lter cutoff frequency for the 2- or 3-wire
pot-wiper or voltage-throttle input. Higher values will make the
throttle more responsive to quick changes. Lower values will
make the throttle less responsive and subject to electrical noise.
HPD SRO Type
HPD_SRO_Type
0x334D 0x00
0 – 3
0 – 3
1 [PCF] Determines the type of HPD (High Pedal Disable) and SRO (Static
Return to Off) protection. One type of check is available for
material-handling vehicles and two types for golf-style vehicles.
Note: If any of the HPD/SRO checks nds an input-sequencing
problem, an HPD/Sequencing Fault (ash code 4-7) is set.
0. HPD/SRO feature is disabled.
1. HPD SRO enabled for material-handling vehicles:
HPD: If throttle input is received before interlock input.
SRO: If direction input is received before interlock input.
The HPD SRO check is made when the interlock input
changes from Off to On. If the throttle input >25% or a
direction input is On an HPD/Sequencing Fault is set.
The HPD/Sequencing Fault is cleared by returning the throttle
input to <25% and the direction inputs to Off.
2. Golf-style HPD that allows direction reversal while driving:
HPD: Throttle input received before interlock, or throttle input
received before direction input while vehicle is stationary.
SRO: None.
The HPD check is made when the interlock input or direction
inputs are Off and the vehicle is stationary. If the throttle input
>25% a HPD/Sequencing Fault is set.
No SRO check is made with this type so the order of the
interlock and direction inputs does not matter.
The HPD/Sequencing Fault is cleared by returning the throttle
input to <25% and the direction inputs to Off.
3. Golf-style HPD that prevents direction reversal while driving:
HPD: If throttle input is received before interlock or direction
input.
SRO: None
HPD check is made when the interlock input or direction inputs
are Off. If the throttle input >25% a HPD/Sequencing Fault is
set. The check is done regardless of vehicle speed so reversing
direction with throttle input >25% will result in a fault.
No SRO check is made with this type so the order of the
interlock and direction inputs does not matter.
The HPD/Sequencing Fault is cleared by returning the throttle
input to <25 % and the direction inputs to Off.
Sequencing Delay
Sequencing_Delay
0x335B 0x00
0.0 – 5.0 s
0 – 1250
0.1 sec Typically, the sequencing delay feature allows the cycling of the
interlock switch within a set time (the dened sequencing delay)
thus preventing inadvertent activation of HPD/SRO. This feature is
useful in applications where the interlock switch may bounce or
be momentarily cycled during operation.
This parameter also works to delay the Hydraulics_Inhibit_Type
at KSI = On (by this this same Sequencing Delay value). See the
commissioning, Chapter 6.
VCL Throttle Enable
VCL_Throttle_Enable
0x3367 0x00
On/Off
On/Off
Off When programmed On the throttle processing with fault detection
will operate normally; however the throttle command will require
VCL to dene the connection between the OS_Throttle and VCL_
Throttle variables. This allows VCL exibility and customization of
throttle processing while still allowing throttle fault detection.
