This is a cycle when the welder would normally be in full control (as in a standard cycle) BUT and external
device is performing an operation that interrupts the cycle. A typical example would be to perform a “test”
on the workpiece to determine its merit before the weld (ultrasonics) cycle begins. If the device tests OK
the weld cycle is allowed to proceed: if the device tests BAD the weld cycle can be aborted by PLC assum
-
ing the User I/O is properly configured to send a Cycle Abort input and the workpiece be handled appropri-
ately using the fixed User I/O functions such as Suspect or Reject Alarm outputs. Also can be used with a
sound enclosure or part clamping device, where the door or clamp arms have to go into place before the
actuator is allowed to travel.
Ext(ernal) Signal
Note: Not a new V9.xx feature but repeated here for clarity. Now the hardware pin and function is selectable
in the User I/O menu.
Used as input to allow external input to trigger amplitude or force change (model dependant).
Or as the start cycle input when in Hand Held mode.
External Sonics delay
A cycle where the ultrasonics are not started after the horn contacts the workpiece until an external device
has determined that the cycle should continue. It may be a test apparatus or perhaps a part-marking opera
-
tion.
Note: The Cycle Abort input can be used to end the welder cycle and not waste time on a workpiece that the
external apparatus determined to be a reject.
External Start
These are both input and output signals, and both must be turned on and assigned a hardware input and out-
put pin in order to function.
Once the unit has received a legitimate start input the External Start output pin activates an external device
(horn clamp cylinder, sound enclosure door, part in position, etc) before moving the horn. When the external
device becomes in position, it then signals the External Start input to commence the welder’s horn travel
and weld cycle. To enable this feature, select the System Configuration menu, then User I/O menu.
While in that menu you can also set “Ext Start Dly” of up to 10.0 sec. to wait before receiving the External
Start input before setting an alarm.
External Trigger delay
This is when the external input normally used for Amplitude or Force Stepping is instead used to delay the
start of ultrasonics, to allow for external device functions prior to the start of welding.
External Beeper
An output pin that operates the same as the internal beeper, and could operate an external (louder) device or
light.
