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 and the
supporting electromechanical devices. Failure to comply
with proper application standards could result in mis-
operation or damage to the controls and/or motors.
FUNCTION 18
STEER PUMP TIME DELAY
( Push CONT 3 )
This function allows for the selection of steer pump
contactor pick up input, either seat switch or directional
switch closing, and adjustment of the time delay for the
contactor drop out.
•
=
Pick up steer pump contactor on seat switch closure
and time delay drop out of steer pump contactor on
seat switch opening.
Range
1.5 to 65 seconds
Setting
Between 0 and 128
Resolution
0.5 seconds per set unit
Example
Setting of 20 = 11.5 seconds
FUNCTION 19
NOT APPLICABLE
This function is not applicable to this type of control and
should not be adjusted.
FUNCTION 20
NOT APPLICABLE
This function is not applicable to this type of control and
should not be adjusted.
FUNCTION 21
NOT APPLICABLE
This function is not applicable to this type of control and
should not be adjusted.
FUNCTION 23
ERROR COMPENSATION
(Push CONT 8)
This function is used to reduce the ripple in the field current
due to the interaction between the motor field design and
the digital field current regulation circuit. The value for this
function will be defined to the vehicle manufacturer by the
GE application engineer.
Important Note: The 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 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
1.625 per set unit
Example
Setting of 20 = 32.5 amps
FUNCTION 25
MONITOR
( Push CONT 10)
This function allows the monitoring of certain control
functions by looking directly at the RAM of the
microprocessor. Because absolute memory locations need
to be known, this function should not be used without
detailed instructions from the GE application engineer.
To ensure optimum operation of the control, this function
must be left with zero stored in this register.
FUNCTION 26
RATIO
( Push CONT 11)
This function sets the ratio between armature and field
current when transitioning from minimum field to maximum
field current. The setting represents the quantity of field
current changed for each 1 amp of armature current
changed.
