Setup Functions for Traction Controller
FUNCTION 1
HANDSET MONITOR ENABLE
(Push 1)
This function allows for use of the handset monitor enable
routine for the control. Set Function 1 to a value of 75 to
enable the routine.
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 6K and 4.0K ohms is
provided.
Range
2% to 15% on time
Set
0 to 255
Resolution
0.05% per set unit
Example:
Setting of 20 = 3% on time
Important Note: This 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
(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. The 1A
contactor will automatically close 2.0 seconds after the
controlled acceleration stops and the accelerator input is
less than 0.5 volts or less than 200 ohms.
Range
0.1 to 22.0 seconds
Set
0 to 255
Resolution
0.084 seconds per set unit
Example:
Setting of 20 = 1.8 seconds C/A
and 2.0 1A time
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 specification sheets and current limit curves
for the control used in your vehicle.
Range
See control C/L curves
Set
0 to 255
Example:
0 = min. current, 255 = max.

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.

by field personnel without the permission of the OEM.
FUNCTION 6
1A DROP OUT CURRENT
(Push 6)
This function allows for the adjustment of the 1A
contactor drop out current. The 1A contactor will be
dropped out and the vehicle motor torque will be limited to
the control current when the set drop out current is
reached.
