Section 6.4 Setup Functions for Traction Controller

FUNCTION 1 MOTOR VOLTS TO ENABLE AUTO REGEN (Push 1)

This function allows for the adjustment of motor volts to enable AutoRegen.

For a setting value of less than 25 (corresponding to a soft release of auto regen and normal regen), the motor voltage to enable regen is calculated by multiplying the value of the setting by 0.375. For example, a setting of 16 will be multiplied by 0.375 to enable regen at 6 motor volts.

Vm = VAL(setting) X .375

For a setting value of greater than 25, the motor voltage to enable auto regen is calculated by subtracting 25 from the setting value and multiplying that number by 0.375. For example, a setting of 33, the motor volts necessary to enable auto regen is (33 - 25) x 0.375, or 3 volts.

FUNCTION 2

CREEP SPEED

 

(Push 2)

This function allows for the adjustment of the creep speed of the vehicle. Creep speed can be adjusted when an accelerator input voltage between 3.9 and 3.3 volts or an

accelerator ohm input between 6.0K and 4.0K ohms is provided.

Range

2% to 15% on-time

Set

0 to 255

Resolution

0.05% per set unit

Example

Setting of 20 = 3% on-time

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 3 ARMATURE CONTROLLED ACCELERATION

(Push 3)

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.

Range

0.025 to 6.3 seconds

Set

0 to 255

Resolution

0.025 seconds per set unit

Example:

Setting of 20 = 0.5 seconds

FUNCTION 4 ARMATURE CURRENT LIMIT (Push 4)

This function allows for the adjustment of the armature current limit of the control. The rating of the control will determine the range of adjustment for this function. Please refer to the specification sheets and current limit curves for the control used in your vehicle.

Range

See control C/L curves

Set

0 to 255

Example:

0 = min. current, 255 = max.

FUNCTION 5 PLUGGING DISTANCE (CURRENT) (Push 5)

This function allows for the adjustment of the plugging distance of the vehicle. The larger the current setting, the shorter the stopping distance.
