ADJUSTABLE FEATURES
SX TRANSISTOR CONTROLS
FUNCTION 7 MIN FIELD CURRENT
This function allows the adjustment of the field weakening
level in order to set the top speed of the motor. This
function is used only when Mode 0 is selected.
Range 0 to 20 amps
Set 51 to 195
Resolution 0.15 amps per set unit
Example Setting of 73 = (73-51) x 0.15
CAUTION: Do not set this function to a value less than 51.
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 8 MAX FIELD CURRENT
This function allows for the adjustment of the maximum
field current in order to obtain the maximum torque of the
motor.
Range 0 to 30 amps
Set 51 to 255
Resolution 0.147 amps per set unit
Example Setting of 251=(251–51)x0.147
= 30 amps
CAUTION: Do not set this function to a value less than 51.
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 9 REGEN ARMATURE CURRENT LIMIT
This function allows for the adjustment of the maximum
armature current limit during regenerative braking.
Range 32 to 350 amps
Set 1 to 255
Resolution 1.38 amps per set unit
Example Setting of 221 = (221x1.38)
FUNCTION 10 REGEN FIELD CURRENT LIMIT
= 3.3 amps
= 212 amps
This function allows for the adjustment of the maximum
field current limit during regenerative braking.
Range 0 to 30 amps
Set 51 to 255
Resolution 0.147 amps per set unit
Example Setting of 180 = (180-51)x0.147
= 19.0 amps
CAUTION: Do not set function 10 to a value less than 51.
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 11 TURF SPEED LIMIT
This function allows for the adjustment of the top speed of
the vehicle (maximum battery volts to the motor) when it is
in Turf Mode.
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 REVERSE SPEED LIMIT
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%
FUNCTION 13 ROLLING RADIUS
This function allows for defining the vehicles rolling radius
in inches.
Range 0 to 25.5 inches
Set 0 to 255
Resolution 0.1 inch per set unit
