PARAMETER RANGE DESCRIPTION
HPD SRO Type 0 – 3 Determines the type of HPD (High Pedal Disable) / SRO (Static Return to Off)
HPD_SRO_Type 0 – 3 protection. One type of checks is available for material-handling vehicles, and
0x30CF 0x00 two types for golf-style vehicles.

HPD/SequencingFault(ashcode47)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% or the direction inputs to Off.
2 Golf-style HPD that allows direction reversal while driving.
HPD: If throttle input is received before interlock or 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%, an 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% or 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%, an 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% or the direction inputs to Off.
Sequencing Delay 0.0 – 5.0 s Typically the sequencing delay feature allows the interlock switch to be cycled
Sequencing_Delay 0 – 1250 withinasettime(thedenedsequencingdelay),thuspreventinginadvertent
0x3009 0x00 activation of HPD/SRO. This feature is especially useful in applications where
the interlock switch may bounce or be momentarily cycled during operation.
VCL Throttle Enable
On / Off When programmed On, the throttle processing with fault detection will operate
VCL_Throttle_Enable On / Off normally; however, the throttle command (see Figure 15, page 114) will require
VCL_Throttle_Enable_Bit0 [Bit 0]  VCLtodenetheconnectionbetweentheOS_ThrottleandVCL_Throttle
0x3099 0x00  variables.ThisallowsVCLexibilityandcustomizationofthrottleprocessing,
while still allowing Throttle_Type 1–4 with throttle fault detection.
