1. Has it ever crossed your mind that
you could operate an automated
machine without using neither
mechanical cams nor PLC or PC con-
trollers?
Have you ever thought about simply
installing an encoder with integrated
electronic cams instead?
But maybe you all don't know what
device is that.
Let's suppose you need to operate a
machine where several operations
are synchronized with the position of
a reference axis (e.g. in presses, tool
changers, packaging machines, etc.).
For some of such processes
you may install mechanical
cams; but they have the
inconvenience of providing
an unchangeable system
and what is more suscepti-
ble to both velocity and
wear. Otherwise, you may
use a PLC or a PC controller
which allow the maximum
flexibility and yet lead to
costs increase.
An integrated-cam encoder is the
inexpensive solution which is able to
accommodate multiple motion con-
trol requirements in low-level
systems. In very plain words we could
state it can be both a basic motion
controller and a feedback transducer
in the same package.
AMR58 is the multiturn optical
encoder equipped with eight pro-
grammable cam outputs.
Each output allows to switch a peri-
pheral device by using the position
signal of the integral encoder. In this
way output signals are more precise
and even actually “real time”.
For each output you can programme
at desired points up to 120 so-called
electronic cams, i.e. changes of state
in each peripheral device. Then you
can save the set configuration to the
internal memory which allows you to
store max. 16 programs. Four inputs
enable to select the desired program
on board, thus making also frequent
changeovers more simple and quick.
Zero setting and counting direction
inputs are further implemented.
AMR58 can be easily programmed via
RS-232 from any Windows pc using
the software tool supplied for free.
Among the key features:
• AMR58 is fitted with 8 indepen-
dent outputs; they are “real time”
and driven directly with negligible
delays even compared with PLCs as
they are controlled via hardware
instead of via microprocessor;
• it allows 16 programs to be stored
in the Flash; they are selectable via
inputs and if necessary editable via
serial port; furthermore position
presets can be independent in
each one;
• it eliminates the need for expensi-
ve PLC and PC controllers;
• it allows to replace mechanical
cams which are susceptible to
velocity and wear;
• thanks to the modular bus cover
design, it can be additionally
equipped with a variety of bus
interfaces (SSI, Profibus, others on
request) to deliver speed and
position information (optio
nal);
•the “all-in-one” configura
tion reduces both space and
time for installation and thus
costs, offering two devices in
the same still compact
enclosure.
AMR58 features a 20-bit
multi-turn overall resolution (12-
bit single-turn x 256 revolutions) and
is offered in both connector and
cable as well as radial and axial out-
put versions.
It comes in a very compact enclosure
with standard 58-mm diameter flan-
ge and solid shaft (Ø 6, 8, 9.52, 10, 11,
12 mm). IP65 protection rate.
It is also available in single-turn ver-
sion with 16 programmable cam out-
puts and an additional analogue
interface.
Have you ever heard about integrated-cam encoders?
AMR58 is the multiturn absolute encoder fitted with eight integrated electronic cams: it generates
ON/OFF phase electrical signals at set points to run peripheral devices and can be additionally
equipped with bus interfaces (on request).
