FUNCTION 6

FW RATIO

 

(Push 6)

This function sets the ratio between armature and field current when operating below the Field Weakening Start point. The setting represents the quantity of field current changed for each 1 amp of armature current changed.

0 to 10

0.029 amps

The ratio value (VAL) is the set value divided by 10 and rounded to the whole number.

Example: Setting of 45 = 45/10 = 4.5 = 4 VAL

IFIELD = VAL (IMOTOR x 0.029)

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.

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.

FUNCTION 9 REGEN BRAKING C/L (Push 9)

This function allows for the adjustment of the Regen braking current limit. High current correlates to shorter stopping distance.

FUNCTION 11 TURN SPEED LIMIT (Push 11)

This function allows for the adjustment of the speed limit (maximum battery volts to the motor) when the SL1 signal is calculated from the turn angle potentiometer by the control card.

Range

100% to 0% battery volts

Set

51 to 180

Resolution

0.78% per set unit

Example

Setting of 71 = 84.4% of battery volts

Note: To disable speed limit, and assure no 1A hold off, set this function to a value of zero.

FUNCTION 12 MAX ARMATURE PERCENT ON ( Push 12 )

Same as function 11, this function allows for the adjustment of the motor speed limit (maximum battery volts to the motor). The dash display mode selection enables the speed limit as well as setting the level of speed limit.
