( Push CONT 1)
This function allows the adjustment of the field weakening
level in order to set the top speed of the motor.
Resolution
Volts Min Max Set Per unit value
36/48 0 60 51 to 255 .314
MIN I
F
= (VAL-51) X .314 (36/48 VOLT)
This MIN FIELD takes effect when the Mode 1 settings are
called for by the interactive Dash Display
.
FUNCTION 49 MODE 1 FIELD WEAKENING START
( Push CONT 2)
This function allows for setting the armature current at
which minimum field current will be achieved.
Range 0 to 414 Amps
Setting 0 to 255
Resolution 1.625 per set unit
Example: Setting of 20 = 32.5 amps
I
M
FWS = VAL x 1.625
This FIELD WEAKENING START takes effect when the
Mode 1 settings are called for by the interactive Dash
Display.
FUNCTION 50 MODE 1 RATIO
( Push CONT 3 )
This function sets the ratio between armature and field
current when operating below the maximum field current
and above the Field Weakening Start point. The setting
represents the quantity of field current changed for each 1
amp of armature current changed.
Volts Max Change Set Resolution
36/48 .48 0 to 40 .024
This RATIO takes effect when the Mode 1 settings are
called for by the interactive Dash Display.
FUNCTION 51 MODE 1 MPH LIMIT
( Push CONT 4)
This function allows for the adjustment of the traction MPH
limit, to limit the achievable top speed of the truck.
VAL x 0.1 = MPH.
This MPH LIMIT takes effect when the Mode 1 settings are
called for by the interactive Dash Display.
FUNCTION 52 MODE 2 MIN FIELD
( Push CONT 5)
Same as Function 48.
This MIN FIELD takes effect when the Mode 2 settings are
called for by the interactive Dash Display.

Mode 2 settings are called for by the interactive Dash
Display.
FUNCTION 54 MODE 2 RATIO
( Push CONT 7 )
Same as Function 50.
This RATIO takes effect when the Mode 2 settings are
called for by the interactive Dash Display.
FUNCTION 55 MODE 2 MPH LIMIT
