FUNCTION 13 FIELD RAMP UP RATE WHILE IN
REGENERATIVE BRAKING MODE
(Push 13)
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 14
INTERNAL RESISTANCE
COMPENSATION
( Push 14 )
This function is used when the Battery Discharge Indicator
is present. Adjustment of this function will improve the
accuracy of the BDI. In order to determine this setting, the
voltage drop of the battery under load must first be
calculated by the following method:
1. Record open circuit voltage (Vo) by measuring the
voltage at the control positive and negative power
terminals.
2. Load the traction motor to 100 amps in 1A and record the
voltage (V
L
) at the control positive and negative power
terminals.
3. Calculate voltage drop (V
Drop
) as follows:
V
Drop
= V
O
- V
L
4. Use the table below to determine the appropriate setting
using the calculated V
Drop
as a reference.

FUNCTION 15
BATTERY VOLTS
(Push l5)
This function allows for the adjustment of voltage range for
controls equipped with the Battery Discharge Indication
function. In order for the BDI to operate properly, the
setting as shown in the table must be entered:
Battery Volts Set Units
24 volts Between 0 and 31
36 volts Between 32 and 44
48 volts Between 45 and 69
36/48 volts Between 184 and 250
No BDI Between 251 and 255
FUNCTION 16
FIELD RAMP DOWN RATE WHILE
IN REGENERATIVE BRAKING MODE
(Push CONT 1)
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 17
JOYSTICK TIMER
( Push CONT 2 )
This function allows for the adjustment of the delay time
from the point at which a direction is selected to actual
vehicle movement.
Range 0 to 25.5 seconds
Setting Between 0 and 255
Resolution 0.1 seconds per set unit
Example Setting of 2 = 0.2 seconds
FUNCTION 18
ARMATURE CURRENT RAMP UP RATE
WHILE IN REGENERATIVE BRAKING
MODE
( Push CONT 3 )
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 19 TACH LOSS TRIP TIME
This function allows for the adjustment of the delay time
from the point at which the tach signal is lost and certain
other conditions are met until the control locks the brakes.
Range 0 to 25.5 seconds
Setting Between 0 and 255
Resolution 0.1 seconds per set unit
Example Setting of 2 = 0.2 seconds
The following functions have function numbers larger than the
numbers on the Handset keyboard. To access these functions,
push the CONT key and the number shown in the instructions at
the same time. THE SEAT SWITCH MUST BE OPEN.
