ADJUSTABLE FEATURES
IT TRANSISTOR CONTROLS
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 8 MAX FIELD CURRENT
( Push 8 )
This function allows for the adjustment of the maximum
field current in order to obtain the maximum torque of the
motor.
Min Max Set
0 50 51 to 255
MAX I = (VAL-51) X 0.269
F
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 9 REGEN BRAKING C/L
(Push 9)
This function allows for the adjustment of the Regen
braking current limit. Higher current correlates to shorter
stopping distance.
Min Max Set
32A 382A 0 to 255
REGEN BRAKE I = (VAL X 1.5)
A
FUNCTION 10 REGEN FIELD CURRENT LIMIT
( Push 10 )
This function allows for the adjustment of the field current
to be used during the regen braking mode.
Min Max Set
0 50 51 to 255
I = (VAL-51) X 0.269
F
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 11
This function allows for the adjustment of the top speed of
the vehicle (maximum battery volts to the motor) when it
is being operated in the forward direction.
Range 0 to 255
Set 0 to 255
Resolution 0.25MPH per set unit
Example: Setting of 60 x 0.25 = 15mph
FUNCTION 12
This function allows for the adjustment of the top speed of
the vehicle (maximum battery volts to the motor) when it
is being operated in the reverse direction.
Range 0 to 255
Set 0 to 255
Resolution 0.25mph per set unit
Example: Setting of 50 x 0.25 = 12.5mph
FUNCTION 13 ROLLING RADIUS
( Push 13 )
This function adjusts for tire rolling radius.
Range 0 to 255
Resolution 0.1
Example RR = 11.4in / 0.1 = 114
Set Value 114
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. Load the traction motor to 100 amps at 100% on-time
of the control and record the open circuit voltage (V
at the control panel positive and negative power
terminal.
2. Load the traction motor to 200 amps at 100% on time
the control and record the voltage (V
panel positive and negative power terminal
3. Calculate voltage dro p (V
V = V - V
