4.2 Function
To determine the position of a plant component, a magnet
is connected to the component. Together they are moved
along a waveguide located inside the BTL.
An internally generated INIT pulse interacts with the
magnetic field of the magnet to generate a torsional wave
in the waveguide which propagates at ultrasonic velocity.
The component of the torsional wave which arrives at the
end of the waveguide is absorbed in the damping zone to
prevent reflection. The component of the torsional wave
which arrives at the beginning of the waveguide is
converted by a coil into an electrical signal. The position of
the magnet and thus at the same time that of the plant
component at a resolution of 5 µm is determined from the
running time of the shaft.
The current position (4 bytes) and velocity (2 bytes) are
displayed cyclically by means of process data via the
CANopen interface.
Up to 2 magnets can be used for FMM (Flexible Magnet
Mode).
The process data displayed cyclically by the BTL contain
the following output values for the available magnets
(max. 2):
– Position (4 bytes)
– Velocity (2 bytes)
