ADJUSTABLE FEATURES
IT TRANSISTOR CONTROLS
FUNCTION 6 Accelerator Input Slope Select
(Push 6)
This function is used to select the accelerator input slope.
Setting Input Voltage Range
0 to 9 3.5 to 1.0 VDC
10 to 19 3.5 to 1.0 VDC
20 to 29 0.5 to 3.0 VDC
30 to 39 0.5 to 3.0 VCD
Linear = 50% travel equal 50% on time
Non-Linear = 50% travel equals 25% on time
FUNCTION 7 MIN FIELD CURRENT
( Push 7 )
This function allows the adjustment of the field weakening
level in order to set the top speed of the motor.
Min Max Set
0 40 51 to 255
MIN 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 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 40 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)
Response
Linear
Non-Linear
Linear
Non-Linear
Resolution Per Unit Value
0.269
Resolution Per Unit Value
0.269
This function allows for the adjustment of the Regen
braking current limit. Higher current correlates to shorter
stopping distance.
Min Max Set
32A 291A 0 to 255
REGEN BRAKE I = (VAL X 1.0156) + 32
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 40 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 100% to 0%
Set 0 to 255
Resolution 0.39% per set unit
Example: Setting of 0 = no speed limit
Setting of 255 = maximum speed
reduction
Setting of 110 =110/255 x 100 = 43%
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 100% to 0%
Set 0 to 255
Resolution 0.39% per set unit
Example: Setting of 0 = no speed limit
Setting of 255 = maximum speed
reduction
Setting of 110 =110/255 x 100 = 43%
