Torque Trigger Option
This option species a torque level to sense when the
upper and lower parts make contact. Prior to contact,
the motor is spinning the tool in the air using a very low
amount torque. At contact, there is an increase in the
torque required to maintain a constant angular velocity,
at which point the weld is considered to start (i.e. the
weld timer and counter are started). Note that the welder
begins to sense the torque after reaching the TRIGGER
Position. To enable this option, press the Torque Trigger
button and then the Enable box on the screen shown in
Figure 5-18. The Torque (% of max.) eld species the
torque level at which the weld will start. The Timeout
(s) value species the amount of time the welder will
wait between reaching the TRIGGER Position and the
sensing of the torque trigger. If torque trigger does not
occur within this time, the machine will abort the cycle
and display an error. The DONE button causes a return
to the main
WELD
tab screen.
For this option to work properly, the torque trigger value
must be set above the torque required to keep the spin
tool running before part contact (i.e. in free air). To set
the torque trigger value correctly, follow these steps:
1. Program all welder settings as desired (refer to
other sections in this manual if needed).
2. Disable the Torque Trigger Option.
3. Verify that the VERTICAL TRAVEL LOWER
LIMIT is set properly to prevent the possibility
of contact between the tool and xture (refer to
TOOLS, SYSTEM SETUP tab menu).
4. Press the RUN button.
5. Run a “dry” cycle (i.e. without parts) by acti-
vating both RUN switches until the spin motor
stops.
6. Read the Peak Torque (%) value on the
RUN
screen. This value represents the torque re-
quired to keep the tool spinning in the air.
7. Repeat Steps 5 and 6 several times to determine
the largest torque value.
8. Enable the Torque Trigger Option and set the
Torque (% of max.) eld to be slightly larger (at
least 2%) than the number from the previous
step.
