Section 6.4 Setup Functions for Traction Controller
FUNCTION 1
MPH SCALING ( When Used )
( Push 1 )
This function allows for the pulses from the tachometer to
be scaled to miles per hour, based on the number of pulses
received by the control in a given time. For example, if you
were scaling to 8 MPH, it would correspond to the length of
time that it took to capture 8 tachometer pulses when the
vehicle is traveling at 8 MPH.

FUNCTION 2
CREEP SPEED
( Push 2 )
This function allows for the adjustment of the creep speed
of the vehicle. Creep speed can be adjusted when an
accelerator input voltage between 3.9 and 3.3 volts or an
accelerator ohm input between 6.0 K and 4.0K ohms is
provided.

Important Note: The function is used to optimize motor and
control performance and this setting will be determined by
GE and OEM engineers at the time of vehicle development.
This setting must not be changed by field personnel without
the permission of the OEM.
FUNCTION 3
ARMATURE CONTROLLED
ACCELERATION AND 1A TIME
(Push 3)
This function allows for the adjustment of the rate of time it
takes for the control to accelerate to 100% applied battery
voltage to the motor on hard acceleration.

FUNCTION 4
ARMATURE CURRENT LIMIT
(Push 4)
This function allows for the adjustment of the armature
current limit of the control. The rating of the control will
determine the range of adjustment for this function. Please
refer to the operating instructions and current limit curves
for the control used in specific vehicle.

FUNCTION 5
PLUGGING CURRENT LIMIT
(Push 5)
This function allows for the adjustment of the plugging
distance of the vehicle. The larger the current setting, the
shorter the stopping distance.
