Have you ever heard about integrated-cam encoders?

Has it ever crossed your mind that you could operate an automated machine without using neither mechanical cams nor PLC or PC controllers? 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 susceptible 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 control 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 programmable cam outputs. Each output allows to switch a peripheral 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 independent 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 expensive 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 (optional); - the “all-in-one” configuration 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 output versions.
It comes in a very compact enclosure with standard 58-mm diameter flange and solid shaft (Ø 6, 8, 9.52, 10, 11, 12 mm). IP65 protection rate.
It is also available in single-turn version with 16 programmable cam outputs and an additional analogue interface.
