Settings for these functions should be made within the
ranges indicated above.
Warning: These settings must be changed by
authorized personnel only, following instructions
supplied by the vehicle manufacturer. Card type
selection must be made within the capabilities of the
control panel used and the supporting electro
mechanical devices. Failure to comply with proper
application standards could result in mis-operation or
damage to the control and/or motors.
FUNCTION 18 BRAKE COIL/LINE CONTACTOR COIL
DROP OUT TIME DELAY
( Push CONT 3 )
This function allows for the adjustment of the time delay
for the brake or line contactor coil drop out when the
control receives a neutral signal from the direction switch
or the start switch opens.
Range
0 to 65 seconds
Setting
Between 0 and 128
Resolution
0.1 seconds per set unit
Example: Setting of 20 = 20 x 0.1 = 2.0 seconds
FUNCTION 19 BRAKE COIL AND LINE CONTACTOR
HOLD VOLTAGE
(Push
CONT
4)
This function sets the voltage level at which the line
contactor and brake coils are held.
Range
0 to 96 volts
Setting
0
to
255
Resolution
0.377 volts per set unit
Voltage = SETTING VALUE/2.65
FUNCTION 20 ARMATURE/BRAKING CURRENT
( Push CONT 5 )
When Function 17 is set to call for tach feedback, this
feature represents the armature current point at which
regen braking is cancelled.
When Function 17 is set for no tach feedback, this feature
represents the braking current level regulated with the
accelerator pedal up and the start switch closed.
Setting: 0 to 128
Resolution: 6.5 per set unit
Current = (128 – SETTING VALUE) x 6.5
FUNCTION 21 PEDAL DOWN/BRAKE REGEN RATE
(Push CONT 6)
This function allows for the adjustment of the rate at which
speed is reduced during regenerative braking under
speed regulation.
Range
0.1 to 25.5 seconds
Set
0 to 255
Resolution
0.086 seconds per set unit
Example:
Setting of 20 = 1.72 seconds
Setting of 1 = Most aggressive braking
Setting of 255 = Least aggressive braking
FUNCTION 22 OVERSPEED DECREASE RATE FOR
FIELD/ARMATURE CURRENT
(Push CONT 7)
This function adjusts the rate at which the armature and
field currents decrease when the accelerator pedal is
released with the start switch closed, or when the vehicle
speed is less than the speed limit.
Setting
1 to 255
Setting of 1 = Most aggressive braking
Setting of 255 = Least aggressive braking
FUNCTION 23 FIELD GAIN
(Push CONT 8)
This function allows for the adjustment of the pedal up
field gain. This value is determined by GE application
engineering and should be set using the OEM setting
specifications for this vehicle.
FUNCTION 24 FIELD WEAKENING START
( Push CONT 9)
This function allows for setting the armature current at
which minimum field current will be achieved .
Range
0 to 414 Amps
Setting
0 to 255
Resolution
