Slope Time. If there is Motor Step-Pulsing, then this is the value associated
with the Low Pulse value of the current. Valid values are from 0.00 to
10.00 rpm.
When the last weld procedure parameters have been entered in the Final
Slope Level, the ACL program will advance to the Procedure Limit Information
Screen. This value can be found at the bottom of the screen under the title
“Max. Scale Change”.
2.17 Procedure Limit Information Screen
This screen is used to set a value on the amount of scaling allowed to
the operator during a weld, as well as setting deviation logging and abort
tolerances on the weld procedure parameters; high and low values for
current, voltage, and motor speed.
2.17.1 Maximum Scale Change
This value limits the amount, by percentage, by which both the Current and
Motor Speed may be scaled, either up or down. This value should be large
to allow for compensations of expected variations in material and welding
conditions, but not so large that control of the welding process is lost.
This value has no effect unless the ACL system is in Production Mode (see
WELDING OPERATIONS in this section).
2.17.2 Current Limit (Tolerance)
These are limits (tolerances) set on the high and low current pulse values
of the weld procedure. Limits are set as a percentage of the actual demand
value along with an amount of time allowed for the current to exceed the
limit.
If the current and time feedback from the welding arc should exceed
the limit, then a deviation will be logged and printed, if the procedure is
programmed to do so.
2.17.3 Voltage Limit (Tolerance)
These are absolute limits (tolerances) set on the welding arc voltage. The
limits that exist on the maximum and minimum voltage values are allowed.
If the voltage and time feedback from the welding arc should exceed
the limit, then a deviation will be logged and printed, if the procedure is
programmed to do so.
2.17.4 Motor Speed Limit (Tolerance)
These are limits (tolerances) set on the high and low motor speed values of
the weld procedure. Limits are set as a percentage of the actual demand
value along with an amount of time allowed for the motor speed to exceed
the limit.
Should the motor speed and time feedback from the motor tachometer
feedback exceed the limit, then a deviation will be logged and printed, if
the procedure is programmed to do so.
2.17.5 Current Abort (Abort Tolerance)
These are abort limits (tolerances) set on the high and low current pulse
values of the weld procedure. The abort limits are set as a percentage
of the actual demand value along with an amount of time allowed for the
current to exceed the limit. Typically these abort limits are greater than
those of the current limits, thus extending or allowing more of a deviation
before aborting the weld.
Should the current and time feedback from the welding arc exceed the
abort limit, the weld will automatically abort and an abort deviation will
be logged and printed, if the procedure is programmed to do so.
