settings to determine the optimal
drive configuration using the
9000XDrive software program. The
tools facilitate upload and download
drive parameters, which can be
changed, saved and ported back to
the drive and then printed or saved
to a file for future reference. Other
operator functions included in the
software are the ability to set
references, start and stop the drive,
and monitor and display signals and
values.
Leverage integrated
power assemblies
Integrated power assemblies (IPAs)
– sometimes called e-Houses – are
ideal for either new mine sites or for
adding capacity at existing facilities.
They are prefabricated metal
enclosures housing power
distribution and industrial control
equipment, such as switchgear, motor
control, power generation and
communication systems
custom‑tailored to individual
specification. IPA implementations
save time, reduce cost and simplify
expansion efforts.
Existing power distribution
centres (PDCs) can be retrofitted with
IPA solutions to extend lifecycles, add
processing power and meet
regulatory requirements. An alternate
containerised, mobile solution allows
the owner the ability to transport a
substation to multiple locations,
thereby reducing cycle time to
redistribute power, where needed,
while simultaneously making
maintenance much faster and easier.
The modular design of Eaton’s
IPAs reduces complexity and
simplifies installation. A rugged,
welded I-beam base provides a solid
foundation for internally mounted
components, allowing either slab or
raised‑on‑piers installation. IPAs can
be built with galvanised steel,
stainless steel or aluminum
construction to address any variety of
site environmental conditions.
The engineered IPA arrives
pre-wired, pre-assembled and
pre-tested to reduce site installation
costs and speed to production.
Onsite contractor installation
expenses are virtually eliminated
because all equipment is installed,
wired, tested and ready to use upon
delivery. A single, coordinated IPA
shipment eliminates multiple onsite
handling and storage expenses. Staff
training maintenance costs are also
reduced as the equipment comes
standardised with proven support
documentation.
These factors can significantly
reduce timeline to production, which
consequently allows earlier startup
of both the facility and the revenue
stream. This jumpstart on uptime
may seem minor, but it can translate
into hundreds of thousands of
dollars for the facility in terms of
speed to first production. If that is
not enough, there are tax breaks in
some countries, allowing accelerated
depreciation of the asset that are also
available as an incentive.
