Section 5.4 Setup Functions for Traction Controller
FUNCTION 1 MPH SCALING
(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 during a given time period.
For example, if you were scaling to 8 MPH, it would
correspond to the length of time necessary to capture 8
tachometer pulses when the vehicle is traveling at 8 MPH.

Example
Example to determine setting:
RR = rolling radius (inches)
Pi = 3.14159265
GR = gear ratio
PPR = pulses per rotation o f the motor
MPH = miles per hour
Setting = 3600 X 2 X Pi X RR X Pulses per MPH
5280 X 12 X GR X PPR X 0.005 X MPH
Setting = 3600 X 2 X 3.14259265 X 9 x1 = 203575 = 18
5280 X 12 X 8.91 X 4 X 0.005 X 1

MODE SELECTION
Where indicated, certain functions can be selected using
the MODE SWITCHES, (SW1 and SW2). The values set
in these function registers will be activated when its Mode
is selected. The SW1 and SW2 logic for mode selection is
as follows:
MODE 1 MODE 2 MODE 3 MODE 4
SW1
0 Volts Batt Volts 0 Volts
SW2 0 Volts 0 Volts
FUNCTION 2 CREEP SPEED
(Push 2)
Mode 1 = FN 65
Mode 2 = FN 77
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 6.0K and 4.0K ohms is
provided.

Example
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)
Mode 1 = FN 66
Mode 2 = FN 78
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.
