Frustrated by conflicting CAN Protocols
refusing to communicate with each other?
ommunication
standardisation for lift-truck
control can seem like wishful
thinking, but savvy engineers
can make devices from
different manufacturers all speak one
common control language, thanks to the
capability of urtis
controllers
aving selected their ideal set of
devices, frustrated engineers regularly
find some on t communicate ith
others, forcing them to approach
manufacturers for e pensive and
time consuming modifications to be
performed void this scenario entirely
by selecting a
e uipped urtis
motor controller that acts as an
“interpreter for devices on the bus,
translating different protocols into a
single new common language without
delay and fuss
his simple, lo er cost
solution can be done without assistance
from urtis although support engineers
are available for assistance with
customisation if preferred

was insistent that the steering had to
simulate the feel of a hydrostatic steering
system his limited the devices for
the man-machine interface forcing the
developer to choose a device that only
ran a custom version of

In summary, Curtis Low voltage
nduction and
motor
controllers give vehicle designers an
easy opportunity to use ne vehicle
configurations, or fully optimise the
energy efficiency of their vehicle,
at the same time as reducing the
overall comple ity of their control
systems
presents endless options
to create a virtual system controller
by integrating all control devices for
hydraulic and electric drives and manmachine interfaces into one system that
accommodates differing
protocols,
even IC engines or transmissions can
be included
ngineers can e plore the
benefits of easily implemented custom
functionality, safe in the knowledge
that e pert urtis customer support
engineers are ready and aiting to help
out if re uired
