FUNCTION 6 ARMATURE ACCELERATION RATE
REVERSE
(Push 6)
This function allows for the adjustment of the rate of time it
takes for the control to accelerate to 100% applied battery
voltage to the motor on hard acceleration in the reverse
direction.
Range 0.1 to 25.5 seconds
Set 1 to 255
Resolution 0.086 seconds per set unit
Example: Setting of 29 = 29 x 0.086 = 2.5 seconds
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.
Range 0 to 37 amps
Set 51 to 255
Resolution 0.185 amps per set unit
Example Setting of 82 = (82-51)x0.185 = 5.7 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 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.
Range 0 to 37 amps
Set 51 to 255
Resolution 0.185 amps per set unit
Example Setting of 251=(251–51)x0.185=37 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
(Push 9)
This function allows for the adjustment of the maximum
armature current limit during regenerative braking.
Range 32 to 240 amps
Set 1 to 255
Resolution 0.8157 amps per set unit
Example Setting of 221 = (221x0.8157) +32
= 212 amps
FUNCTION 10 PLUG/REGEN FIELD CURRENT LIMIT
( Push 10 )
This function allows for the adjustment of the maximum
field current limit during regenerative braking.
Range 0 to 37 amps
Set 51 to 255
Resolution 0.185 amps per set unit
Example Setting of 180 = (180-51)x0.185
= 24 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 11 TURF SPEED LIMIT
(Push 11)
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% (or creep speed)
Set 51 to 170
Resolution 0.78% per set unit
Example: Setting of 0 = no speed limit
Setting of 170 = maximum speed
reduction
Setting of 122 =100%-((122-51) - (creep val/8)) x 0.78
