FUNCTION 14 INTERNAL RESISTANCE
COMPENSATION
( Push 14 )
This function is used when the Battery Discharge Indicator
is present. Adjustment of this function will improve the
accuracy of the BDI. In order to determine this setting, the
voltage drop of the battery under load must first be
calculated by the following method:
1. Record open circuit voltage (Vo) by measuring the
voltage at the control positive and negative power
terminals.
2. Load the traction motor to 100 amps in 1A and record the
voltage (V
L
) at the control positive and negative power
terminals.
3. Calculate voltage drop (V
Drop
) as follows:
V
Drop
= V
O
- V
L
4. Use the table below to determine the appropriate setting
using the calculated V
Drop
as a reference.

FUNCTION 15
BATTERY VOLTS
(Push l5)
This function allows for the adjustment of voltage range for
controls equipped with the Battery Discharge Indication
function. In order for the BDI to operate properly, the
setting as shown in the table must be entered:
Battery Volts
Set Units
24 volts Between 0 and 31
36 volts Between 32 and 44
48 volts Between 45 and 69
36/48 volts Between 184 and 250
No BDI Between 251 and 255
FUNCTION 16
PEDAL POSITION PLUG
(Push CONT 1)
This function will allow the adjustment of the pedal position
plug range. Pedal position will reduce the plugging current
to the current value set by this function as the accelerator
is returned to the creep speed position. Maximum plug
current is obtained with the accelerator in the top speed
position.
Resolution
Example
Min Max Set Per unit value If set at 20
26 226 0 to 255 0.78 amps 41.6 amps
55 455 0 to 255 1.57 amps 86.4 amps
55 655 0 to 255 2.35 amps 102 amps
To disable the pedal position plug function, adjust this
current value to the same current value as the plug
distance current.
Example: If plug distance current, Function 5, is set at 350
amps, then set pedal plug current at 350 amps. With this
setting, pedal position will have no effect on plugging
distance.
Note: Vehicles equipped with regenerative braking will
vary the regen current with pedal position. However,
minimum regen current is fixed at 50 amps. The pedal
position will vary regen current between 50 amps and the
maximum value of regen current set by Function 9.
FUNCTION 17
CARD TYPE SELECTION
( Push CONT 2 )
This function allows for the selection of the card type used
for your vehicle’s application. The table below shows the
setting to select card application type, depending on which
control card is used. Note that the right (slave) control for
a dual motor proportioning system will be set differently
than the left (master) control.
Note: Non-Auto Plug/Regen logic cards must be used for
settings below:
Functions Standard Regen
Std C/L 0 to 4 40 to 44
Std C/L (Right) 64 to 68 104 to 108
High C/L 5 to 9 45 to 49
High C/L (Right) 69 to 73 109 to 113
The following functions have function numbers larger than the
numbers on the Handset keyboard. To access these functions,
push the CONT key and the number shown in the instructions at
the same time. THE SEAT SWITCH MUST BE OPEN.
