Section 6.4 Setup Functions for Traction Controller
FUNCTION 1
ADJUSTABLE MOTOR EMF FOR
PLUGGING OR REGEN
(Push 1)
This function allows for the adjustment of the level of
motor EMF required for plugging or regenerative braking.
The control will default to standard regen functionality if
the setting is higher than a value of 60.

FUNCTION 2
CREEP SPEED
( Push 2 )
This function allows for the adjustment of the creep speed
of the vehicle. Creep speed can add 13 % to the percent on
time at the slowest speed range.
Range
2% to 15% on time
Set
0 to 255
Resolution

ARMATURE CURRENT LIMIT
(Push 4)
This function should always remain set at 255 (maximum
current limit) for this family of controls.
FUNCTION 5
COUNTER EMF TRIP POINT FOR AUTO
BRAKING
(Push 5)
This function allows for the adjustment of the speed at
which the truck will activate auto braking, after the
accelerator pedal is released. The truck speed correlates
to the amount of voltage produced by the traction motor
when it is coasting. The setting of this function represents
the motor voltage.
Range
0 to 100 volts
Set
0 to 255
Resolution
0.392 volts per set unit
Example:
Setting of 20 = 7.84 volts
FUNCTION 6
AUTO CALIBRATION OF ACCELERATOR
POTENTIOMETER
(Push 6)
This function allows for the auto calibration of the
accelerator potentiometer. This function should be left set
to a value of zero during normal truck operation. To
activate the auto calibration routine, set this function to a
value between 15 and 20, and refer to Section 8.0 of this
handbook for detailed instructions covering the auto
calibration procedure.
FUNCTION 7
MIN FIELD CURRENT
( Push 7 )
This function allows the adjustment of the field weakening
level in order to set the top speed of the motor.
