Setup Functions for Traction Controller

FUNCTION 1 MOTOR VOLTS TO ENABLE AUTO REGEN
(Push 1)
This function allows for the adjustment of motor volts to
enable AutoRegen.
For a setting value of less than 25 (corresponding to a soft
release of auto regen and normal regen), the motor voltage
to enable regen is calculated by multiplying the value of the
setting by 0.375. For example, a setting of 16 will be
multiplied by 0.375 to enable regen at 6 motor volts.
Vm = VAL(setting) X .375
For a setting value of greater than 25, the motor voltage to
enable auto regen is calculated by subtracting 25 from the
setting value and multiplying that number by 0.375. For
example, a setting of 33, the motor volts necessary to
enable auto regen is (33 - 25) x 0.375, or 3 volts.
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

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.

Example:
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.

Example:
FUNCTION 5 REGEN RAMP RATE
(Push 5)
This function allows for the adjustment of the rate that
regen braking is applied .
Armature current adjustment setting range: 0 to 126
Higher values of this setting correspond to a faster rate of
change in armature current.
Field current adjustment setting range: 0 to 126
0 - 42 Fastest rate of change in field current
