Starting A Weld Cycle
All weld cycles must be initiated from the
RUN
screen
after the machine is initialized and with the press at the
top-of-stroke position. If not already on this screen,
press the
RUN
button first (see Figure 5-2). If you had
powered down the welder or pressed the Abort button,
the screen may instruct you to press the
RESET FAULT
button and then reset the machine by activating the
RUN
switches. After the reset process is completed, the
welder is ready to run a cycle, which is indicated by
the smiley face in the upper left corner of the screen.
If a frowning face appears instead, it signifies that
the welder is not ready for one of several reasons (for
example, the part presence sensor is not activated if the
Part Present option is enabled).
To run a cycle, press both
RUN
switches simultaneously.
The press will begin to descend and spin motor will
accelerate. Both servos will reach their programmed
weld speeds by the time the press reaches the trigger
position (defined in
SETUP
>
PRE-TRIGGER
tab >
TRIGGER
Position
). The Trigger Indicator (see Figure
4-1) will turn on when the weld starts, which occurs
at the Trigger position if the Torque Trigger Option
is disabled, or when the trigger torque is sensed if the
Torque Trigger Option is enabled. The weld phase
continues until the selected welding parameter (time,
number of rotations, vertical distance, or energy) has
been reached, at which point the Trigger Indicator turns
off. The spin motor then stops and the welder begins the
hold phase, during which the press moves according to
the settings defined in the
Hold Setup
menu. To complete
the cycle, the press retracts to the top-of-stroke position
and the
RUN
screen is populated with weld process data
results. The base switches must remain actuated until
the start of the hold phase; otherwise, the cycle will be
aborted and no weld data will be displayed.
If a weld cycle completes successfully, the smiley face
appears to indicate that the machine is ready to run
another cycle. If a cycle terminates abnormally, a fault
message will be displayed on the screen describing
the error condition. The fault must be cleared and the
welder reset before another cycle can be initiated.
