of these segments individually. This allows the Br-EFB to control uneven loads, or
unbalanced loads that go over fulcrum. Even if the load changes over time (the
actuator bore gets smoother, the hydraulic fluid gets thinner as it gets hotter, or the
motion base is loaded with a bunch of 300 pound football players), the Br-EFB can
compensate for this.
The Br-EFB can be set up
over ethernet using its built in
web server and just about any
b r o w s e r o n a n y t a b l e t ,
smartphone or computer. You
can also use its textual menu
a n d G i l d e r Te r m , e i t h e r
through an TCP connection
over ethernet, or through the
networkable Rs-422 serial
port.
You can configure the
Br-EFB using the PID Setup
Wizard or manually. The first
thing you need to tell the
Br-EFB is the range of voltage
expected on the position and
Compliance Feedback inputs
for the axis. Set these to
match the expected outputs
from your position and Compliance Feedback sensors. If you are using
potentiometers, you will probably be using the Br-EFB's +/10 vdc reference outputs,
and will set the inputs to match.
The next step is to tell the Br-EFB where the ends of the actuator's travel are
located. If the actuator can safely be moved to both its mechanical stops, then the
Br-EFB can find the endpoints for you. The Br-EFB will then back off slightly to set the
normal range of movement to just short of the ends of the actuator. Otherwise, you
can use the web menu to ‘Jog’ the actuator to where you want to place each end of
the actuator's stroke, and then lock them in. Once the endpoints have been set, the
Br-EFB will do its best to keep the actuator within this range of movement.
As you are setting the endpoints, the Br-EFB is detecting the 'phase' of the actuator
and Position Feedback hardware, and automatically correcting for any phase-flipped
wires or hoses.
