Process Setup
The first submenu of Process Setup to consider is:
Travel Limit
This setting sets the position limit the servo press
is permitted to travel. Its purpose is to prevent
contact between the horn and fixture. This position is
monitored continuously throughout the weld.
See additional information on Page 55.
Initiate Mode
Initiate Mode controls the way a cycle is started, using
either of two modes, Manual or Auto.
Manual
The cycle is started by depressing both operate switches
on the press base (Operate Switch 1 and Operate Switch
2) within 0.35 seconds of each other.
Depress the operate switches continuously until the
trigger switch on the press has activated or until the
ultrasonic signal is applied.
Latch on Bad Part
When this feature is active (It is available only with the
Manual Initiate mode.), the cycle stops when a bad part
is detected, and
SYSTEM LOCKED,
Bad Part Limit
Exceeded,
LATCHED
appears on the
iQ
display. The
operator must deal with the
LATCHED
message before
a new cycle will start.
The next cycle will not activate until the latch is cleared.
There are two ways the latch can be cleared:
• Remove the
LATCHED
Message from the Display
1. Go to the Main Menu.
2. Go to
Utilities
, and then to
Part Count Settings
.
3. Enable
Clear Bad Part
. (See Figure 5-7 to the
right.)
When these three steps are completed, the operator can
press the
ENTER
key to clear the latch, or
• Activate the System Latch Reset Input
The System Latch Reset Input signal (Pin 12 of J2, the
System Inputs connector) can be activated.
See Page 20 for information about Pin 12 of the System
Inputs (J2) connector. The pin can be used for latch reset.
What is a “bad part”? Bad part limits de-
fine what is considered to be a bad part.
If the
UPPER
limit of a selected charac-
teristic is reached during its phase of the
weld cycle, the weld process is stopped,
and the part is identified as a bad part.
If the
LOWER
limit of a selected parameter
is not reached by the end of its phase of
the weld cycle, the assembly process is
stopped, and the part is identified as a
bad part.
