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 ) at the control positive and negative power
L
terminals.
3. Calculate voltage drop (V
V = V - V
Drop O L
4. Use the table below to determine the appropriate setting
using the calculated V

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.
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
