Introduction
The 5000-10 Auto-Setup Module (ASM) allows the OmniLink 5000 Press and Automation control to
set up press shut height, counterbalance air pressure, cushion air pressures, and hydraulic overload
pressure settings automatically when jobs are recalled from memory. It consists of a base 5000-10
microprocessor board that installs in the OmniLink extended card rack, and additional modules that may
be mounted on the base board to provide pressure or shut height adjustment functions. When one slide
adjust is provided , up to four air systems and a hydraulic overload can be adjusted. For double action or
banjo presses with two slide adjust systems, up to two air systems and a hydraulic overload can be
adjusted.
Section 1.1
Counterbalance Control
The proper setup of the air counterbalance system in a press is often thought of as a relatively
unimportant detail. In fact, the counterbalance performs a very critical function. By countering the
weight of the slide and its associated tooling a properly adjusted counterbalance:
Takes up bearing clearances before the die closes at the bottom of the stroke, reducing bearing load
and impact.
Helps reduce gear tooth impact in geared machines by maintaining drive edge gear tooth contact in
the press downstroke.
Decreases the downstroke stopping time of the press since less load is seen by the brake in the
downstroke.
Enhances safety by reducing the possibility that the slide will free fall, if the brake is released and
the clutch is not engaged.
Causes less total energy to be used by the press.
Increases drive motor life by reducing peak motor currents.
None of the foregoing advantages will be realized if the counterbalance pressure is set too low. But a
counterbalance pressure that is set too high is also detrimental to the press, causing excessive clutch
wear and loss of flywheel energy in the downstroke before material is contacted by the dies.
By setting the pressure automatically when a job is recalled, the OmniLink 5000 assures that the
pressure is correct for the tooling used. This not only reduces machine maintenance, but increases safety
and speeds up job setup tremendously. In addition, the Auto-Setup module sets the correct pressure for
each die, rather than an approximate pressure for a range of die weights from tables provided with
manually adjustable counterbalance systems.
Section 1.2
Cushion Control
Quick die change is becoming increasingly important to maintaining a competitive edge. By controlling
up to four cushions automatically, the OmniLink 5000 can shorten die change and assure a correct setup
in the least amount of time.
