during each loop, this results in overshoot and
instability of the speed.
The closed loop sensitivity can be set from 0
to 99.9%.

Screen 19 SENSING DELAY
This screen allows a delay to be set by turning
the adjust knob to increase or decrease the value.
During the delay time, the closed loop mode is
turned off, this avoids any instability during the
acceleration time of the motor. It is recommend-
ed to always allow a short time for the system to
stabilize before closed loop is active.
Sensing delay can be set from 0 to 9.9 sec-
onds.
Press the touch pad with the down arrow to
proceed to the next screen.
Screen 20 DISPLAY
If a signal is being received from a tach-gen-
erator tted on the wire feed drive motor, the
control can display the actual wire feed speed.
To do this, the adjust knob should be turned to
select Actual.
If there is no tach-generator tted and therefore
no tach-generator signal, the adjust knob should
be turned to select Preset. In this mode, the
display will provide a wire feed speed reading
which is based upon the wire feed speed which
has been programmed (Screen 2).
Press the touch pad with the down arrow to
proceed to the next screen.
Screen 21 HIGH LIMIT
This screen allows the maximum speed of the
wire feeder to be set by turning the adjust knob
to increase or decrease the value.
Following the pre-delivery calibration routine,
the high limit value will be preset at the factory
and should not be changed when the system is
received.
It will be necessary to change this value only if
a change is made in the drive mechanism, i.e.
the gear ratio is changed to provide a different
wire feed speed. If this happens, contact Jetline
to verify the correct speed to be entered in this
screen.
Screen 30 allows the unit to be setup for inch or
metric readings. If the unit is set for inches, the
maximum speed should be entered in inches per
minute. If the unit is set for metric readings, the
equivalent maximum speed in centimeters per
minute should be entered.
The high limit can be set to a maximum number
of 9999.99 inches (or centimeters) per minute.
The minimum number which can be set is one
digit more than the number set for the low limit
(Screen 24).
Press the touch pad with the down arrow to
proceed to the next screen.
Screen 22 HIGH OUTPUT
This screen allows the high output of the control
to the wire drive motor to be set by turning the
adjust knob to increase or decrease the value.
The high output represents the maximum DC
output voltage which is transmitted to the motor
drive control. The number has been predeter-
