high setpoint The tonnage limit above which AutoSet generates a high tonnage
fault, stopping the press and displaying a fault message. To
calculate the high setpoint, AutoSet multiplies the percent high
tolerance set on the AutoSet processor board by the
reference
tonnage and adds this value to the reference tonnage.
linearity The proportional increase of tonnage readings with increasing
load, a measure of how well the press has been calibrated. When
a press has been calibrated for linearity, AutoSet should read 40
tons when 40 tons is applied to the load cells and 80 tons when 80
tons is applied.
nuisance stop A press shutdown initiated by AutoSet because setpoints have
been set too close to normal tonnage values or normal tonnage
variations. As a result, setpoints are regularly exceeded, causing
unnecessary press shutdowns.
reference tonnage The highest tonnage measured by AutoSet during the sample
period.
repeatability setpoint The limit in tonnage variation from one stroke to the next above
which AutoSet generates a repeatability fault, stopping the press
and displaying a fault message. AutoSet calculates the
repeatability setpoint by multiplying the percent repeatability
tolerance set on the AutoSet processor board by the
reference
tonnage .
sample period The number of strokes during which AutoSet collects and
measures press tonnage in order to calculate high tonnage and
repeatability setpoints. AutoSet calculates setpoints using the
highest tonnage measured during the sample period as the
reference tonnage.
tonnage fault A press shutdown initiated by AutoSet because tonnage has
fluctuated enough to exceed the high, low, repeatability, or
reverse setpoint. A fault may be caused by a stuck part,
significant change in material thickness or hardness, slug
stacking, load imbalance, misfeed, broken punch, end of stock, or
any die malfunctions.
