MIN FIELD CURRENT
FUNCTION 7
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.
0 to 20 amps
Range
51 to 195
Set
0.15 amps per set unit
Resolution
Setting of 73 = (73-51) x 0.15
Example
= 3.3 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.
MAX FIELD CURRENT
FUNCTION 8
This function allows for the adjustment of the maximum
field current in order to obtain the maximum torque of the
motor.
0 to 30 amps
Range
51 to 255
Set
0.147 amps per set unit
Resolution
Setting of 251=(251–51)x0.147
Example
= 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.
32 to 350 amps
Range
1 to 255
Set
1.38 amps per set unit
Resolution
Setting of 221 = (221x1.38)
Example
= 212 amps
FUNCTION 10
REGEN FIELD CURRENT LIMIT
This function allows for the adjustment of the maximum
field current limit during regenerative braking.
0 to 30 amps
Range
51 to 255
Set
0.147 amps per set unit
Resolution
Setting of 180 = (180-51)x0.147
Example
= 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.
100% to 0%
Range
0 to 255
Set
0.39% per set unit
Resolution
Setting of 0 = no speed limit
Example:
Setting of 255 = maximum speed
reduction
Setting of 110 =110/255 x 100
=43%
REVERSE SPEED LIMIT
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.
100% to 0%
Range
0 to 255
Set
0.39% per set unit
Resolution
Setting of 0 = no speed limit
Example:
Setting of 255 = maximum speed
reduction
Setting of 110 =110/255 x 100
=43%
ROLLING RADIUS
FUNCTION 13
This function allows for defining the vehicles rolling radius
in inches.
0 to 25.5 inches
Range
0 to 255
Set
0.1 inch per set unit
