Incremental Encoders

Incremental encoders from EUCHNER have a graduated code disk as their basis for the measurement of angular steps. These radial gratings of lines and gaps form an incremental track. When a light source is transmitted through the code disk a signal is generated when the disk is rotated. This optically generated signal is converted into two 90° phase-shifted square-wave pulse trains. The measured angle is determined by counting these signals. The resolution is dependant on the number of graduations per revolution. A second track is used to generate a reference mark. EUCHNER incremental encoders feature high resolution (up to 6000 increments per revolution) and high measuring accuracy. The EMC requirements of CE are satisfied.

Examples of applications for incremental encoders are:

machine tools
textile machinery
printing presses
wood working machines
forestry machinery
handling technology
conveying and storage technology
robotics

Absolute Encoders

Absolute absolute encoders from EUCHNER represent dimensions using a code disk with tracks, the number of which corresponds to the resolution. The code disk is scanned using a highly integrated multiple opto-electronic system of light barriers. This optical ASIC features high measuring accuracy. Its long-term reliability is improved by automatic control of LED intensity. Absolute encoders require no counters or recognition of direction, as a uniquely encoded digital signal is assigned to each measuring step. As a result, the position value is available again after switching on or restoring power, so no referencing is required. EUCHNER absolute encoders feature high resolution (up to 8192 positions) and high measuring accuracy. All outputs are equipped with a non-latching thermal cutout. The EMC requirements of CE are satisfied.

Examples of applications for absolute encoders are:

machine tools
textile machinery
printing presses
wood working machines
handling technology
conveying and storage technology
robotics

Programmable Cam Switch

A compact Cam Switch in the housing of an absolute encoder

The programmable electronic cam switch PNS replaces mechanical switches and controllers. It improves their functionality in terms of accuracy, universality, freedom from wear and simple handling. The user can change the parameters of the cam switch within a very short time, resulting in short set up times and maximum flexibility. State-of-the-art electronics and the PNSWIN graphical user interface provide simple, visual and convenient programming of the cam switch.

The PNSWIN Interface

The PNSWin graphical user inter-face makes it easy for the user to

set and clear cams
copy whole cam tracks
copy complete programs
delete complete programs
set and interrogate the zero point
upload and download the parameter set to and from the PNS
archive parameter sets etc.

This straightforward principle is employed in the PNS programmable electronic cam switch. A "set" cam is described by its switch-on and its switch-off points. Between these two points, the output is active, i.e. the cam is set.

Advantages

The PNS provides the following advantages over mechanical cam controllers:

The cams are very easy to change, i.e. clear, set or relocate.
For each cam track, a great number of cams can be set, with very accurate switching points.
Several different programs can be selected (short tooling times).
Electronic zero point adjustment eliminates the need for a specific mechanical installation position.
Parameter sets can be easily archived on the PC.
Several devices can be created with identical parameter sets.

Features

1000 cams, distributed in any desired arrangement among cam tracks and programs.
16 channels / cam tracks (digital outputs).
16 programs, selected via 4 digital inputs.
Super-high resolution 0.088 degrees (4096 positions per revolution).
Outputs programmed depending on angular position via PC with menu-driven user interface (PNSWIN).
Programming can be done without a connected cam switch.
Any output combination can be programmed, for each channel and each position.
Programmable code direction.
Precision cam adjustment via PC.
Data transfer to and from the PC through serial V24 interface.
Zero point can be set with device installed, via external input or PC.
Data backup to EEPROM (requires no internal power source, data retained even when power fails).

Angular Positioning Systems

Construction and Function

The compact angular positioning systems PSU and PSV consist of the absolute angular position transducer, microcomputer, input and output amplifier subassemblies. The angular position transducer is a digital absolute angular position transducer for detecting actual values. The input amplifier is equipped with opto-couplers and forwards the specified command information (e.g. mode, required end position) to the microcomputer. The microcomputer processes the actual values furnished by the angular position transducer and the command values from the microcontroller. Accounting for the machine-specific data stored in the memory of the microcomputer (angular positions, switching points), the signals for direction of rotation, speed and position are available at the output. The output amplifier converts the microcomputer's control commands to the appropriate output signal levels. The outputs are overload protected and short-circuit-proof. A software plausibility check monitors the angular position transducer and the input information, ensuring a high degree of operating reliability. Consistent use of microelectronics, rugged construction, the use of high quality materials and components, the compact design and high degree of protection (IP65) guarantee maximum flexibility and simple use of these positioning systems. In the electronic Multiturn PSU-M and PSV-M, the current angular position is saved to non-volatile memory when the power supply is disconnected. Correct assignment of the position upon restarting requires that the shaft of the PSU-M / PSV-M is not moved more than 180° while power is absent.
