FUNCTION 1 MPH SCALING
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. Note: This function should
always be calculated using MPH.
0 to 1.28 seconds Range
0 to 255 Set
0.005 seconds per set unit Resolution
Setting of 18 = 0.09 seconds Example
Example to determine sitting:
RR = Rolling Radius (Inches)
Pi = 3.14159265
GR = Gear Ratio
PPR = Pulses per rotation of motor
Setting = 3600 X 2 X Pi X RR
5280 X 12 X GR X PPR X .005
Setting = 3600 X 2 X 3.14159265 X 9
5280 X 12 X 8.91 X 4 X .005
Setting = 203575
11290
Setting = 18
CREEP SPEED FUNCTION 2
This function allows for the adjustment of the creep speed
of the vehicle when the accelerator potentiometer is at its
minimum value and the start switch is closed.
2% to 15% on time Range
0 to 255 Set
0.047% per set unit Resolution
Setting of 205=(205x0.047)+2 Example
= 11% on time
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 ACCELERATION RATE
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 in the forward
direction.
0.1 to 25.5 seconds Range
1 to 255 Set
0.086 seconds per set unit Resolution
Setting of 20 = 20 x 0.086=1.72 seconds Example:
FUNCTION 4
MAX ARMATURE CURRENT LIMIT
This function allows for the adjustment of the armature
current limit of the control during motoring.
0 to 350 amps Range
0 to 255 Set
1.38 amps per unit Resolution
Setting of 255 =(255x1.38) Example:
= 350 amps
FUNCTION 5 NOT USED
FUNCTION 6 ODOMETER CALIBRATION
This function is used to adjust the number of tachometer
pulses (divided by 64) that are equivalent to 0.1 MPH.
0 to 255 Range
0 to 255 Set
RR = rolling radius Example:
GR = gear ratio
PPR = pulses per rotation of motor
