high setpoint
The tonnage limit above which AutoSetPAC generates a high tonnage fault,
stopping the press and displaying a fault message. To calculate the high
setpoint, AutoSetPAC multiplies the high setpoint percentage specified in
Program mode by the
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, AutoSetPAC should read 40 tons when 40 tons is
applied to the load cells and 80 tons when 80 tons is applied.
low setpoint
The tonnage limit below which AutoSetPAC generates a low tonnage fault,
stopping the press and displaying a fault message. To calculate the low
setpoint, AutoSetPAC multiplies the low setpoint percentage specified in
and subtracts this value from the
reference tonnage.
nuisance stop
A press shutdown initiated by AutoSetPAC 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 AutoSetPAC during the sample period.
repeatability setpoint The limit in tonnage variation from one stroke to the next above which
AutoSetPAC generates a repeatability fault, stopping the press and
displaying a fault message. To calculate the repeatability setpoint,
AutoSetPAC multiplies the repeatability setpoint percentage specified in
Program mode by the
reverse setpoint
The reverse tonnage limit above which AutoSetPAC generates a reverse
tonnage fault, stopping the press and displaying a fault message. To calculate
the reverse tonnage setpoint, AutoSetPAC multiplies the reverse setpoint
percentage specified in Initialization mode by the Initialization setting for the
full-scale capacity of the press.
sample period
The number of strokes during which AutoSetPAC collects and measures
press tonnage in order to calculate high, low, and repeatability setpoints.
AutoSetPAC calculates setpoints using the highest tonnage measured during
the sample period as the reference tonnage.
