Encoders Technical Description EUCHNER- encoders are sensors for absolute-encoded or step-bystep incremental-encoded detection of angles of rotation. A rotating, digital code disk representing dimensions is precisely scanned by miniature opto-electronic light barriers and converted to electrical output.

Absolute encoders are systems for measuring angles of rotation using encoded detection of the measured quantity. Each angular position has unique code information assigned to it. Assigned to each track of the dimensional representation (S1, S2, S3, S4 etc.) is one bit of code information and, in the parallel output interface, one digital output signal.

Besides pure measuring systems with resolutions of over 8,000 positions per revolution, programmable absolute encoders not only reduce machine commissioning times but also mean that the user has fewer devices to deal with. In the case of incremental encoders, the value is acquired by electrically counting the periodic divisions of the material measure or the electronic output signals (A, B). These encoders have an additional output signal (R, reference point) to uniquely define the absolute position.

Angular positioning systems PSU / PSV with integrated open and closed loop position control, as asynchronous NC control systems, are an economical alternative for auxiliary axes on large series machines. But PC based programming and optimisation with a graphical user interface is also a completely new, practical and time-saving way of commissioning small series and test machines. The programmable electronic cam switch PNS, a compact unit in an angular position transducer housing, not only replaces mechanical controllers but also improves their functionality in terms of accuracy, universality, freedom from wear and simple handling.

Mechanical Construction The absolute encoder is constructed from a stator, consisting of housing or flange, cover and scanning system, and a rotor with a shaft to which the code disk is mounted to represent the dimensions.

Electrical Construction In EUCHNER absolute encoders, the code disk is scanned by a highly integrated multiple optoelectronic system of light barriers. The special feature of this optical ASIC is its high measuring accuracy. Automatic control of the LED intensity also improves long-term reliability.

Encoders Conformity / EMC Requirements Absolute encoders are used as components in a larger system.

The following standards are applied in particular:

The operator or owner of this larger system, e.g. a machine, is responsible for complying with the safety and accident prevention regulations that apply to the given application.

      

The encoder must be installed by authorised personnel.

EUCHNER absolute encoders, positioning systems and programmable cam switches meet the requirements of European EMC Directive 89/336/EEC.

EN 50081-2 EN 50082-2 ENV 50140 ENV 50141 EN 55011, class A, group 1 IEC 801-2 IEC 801-4.

The test severity used is the class for "typical industrial environment". The use of these products in a machine does not guarantee that the entire machine or installation conforms to the European Directive.

Installation Notes As a general rule, cables and leads must be laid and routed to reflect EMC requirements. The connecting leads must be shielded (common outer shield). Ensure that there is a good ground connection between the machine body and housing flange of the absolute encoder. In encoder versions with built-in flange socket, attach the lead shield at the free connector via an EMC cable screw union with shield bushing or shield cone. Ground the shield at the lead end to a central frame location, e.g. in the distribution board or in the switch cabinet, with low impedance and low inductance (grounding strip). The reference point for the electrical characteristics - especially voltages given in the technical specifications is the plug connector or a lead length of 2 meters.

Encoders Definitions Starting Torque

Code Direction

The starting torque of the absolute encoder is the torque required to set the shaft in rotational motion from standstill.

The code direction indicates the direction of rotation for which the output code corresponds to increasing values, as viewed when looking at the encoder shaft.

Operating Temperature Range

Clockwise (cw)

The operating temperature range specifies the temperature limits between which the specified error limits must not be crossed. The maximum operating temperature is the temperature that occurs on the housing of the absolute encoder at maximum speed and maximum operating voltage.

Counter-clockwise (ccw)

Error Limit The error limit indicates, for static measurements, the biggest positive or negative deviation of any angle of rotation referred to the set point.

Output Code

Bearing Service Life

The output code is the unique coding of the measured values at the output of the absolute encoder using a defined scheme. With the exception of absolute encoders of series ending with -A (factory programmed) and -PC (PC programmable), the output code is identical to the pitch code.

The bearing service life specifies the life of the encoder bearing, accounting for maximum shaft load and maximum operating speed.

Operating Torque The operating torque is the torque required at a specified speed to keep the rotor rotating against frictional forces.

Storage Temperature Range The bearing temperature range specifies the temperature limits between which the absolute encoder can be stored or transported without damage.

Absolute Encoders Maximum Output Frequency The maximum output frequency is the frequency at which the correct code value sequence is still ensured at the output. The following relationship exists between the speed n and the output frequency f: n rpm

=

60 ×

f / (1 / s ) No. of steps

Incremental Encoders Maximum Output Frequency The output frequency is the repetition rate of the output signals A or B at which signals still capable of evaluation are guaranteed. A signal capable of evaluation is characterised by the fact that the phase difference between signals A and B changes by no more than 50 % in comparison with the value at lower speeds. In the case of incremental encoders, the following relationship applies between the speed n and the output frequency f: n rpm

=

60 ×

f / ( 1/ 1/ s) No. of steps

Maximum Operating Speed The maximum operating speed is the highest permitted speed at which the absolute encoder can be operated without damage.

Measuring Step Deviation The measuring step deviation is the maximum measuring deviation (angle deviation) from one measuring step to the next.

Measuring Steps α The measuring step α is the smallest measurable angle.

Pitch Code The pitch code is the unique coding of the measured quantity (angle of rotation or angular position) on the dimensional representation (code disk) using a particular scheme (e.g. gray code).

Absolute Encoders 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 optoelectronic system of light barriers. This optical ASIC features high measuring accuracy. Its long-term reliability is improved by automatic control of LED intensity.

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 requirement requirementss of isfied.

Examples of applications for absolute encoders are:  

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.

Angular Positioning Systems PSU / PSV Angular Positioning Systems The angular positioning systems PSU PSU and PSV are designed for positioning tasks in industrial applications. The absolute angular position transducer, sequence control system and closed-loop position control combined in a single unit. Control signals for direction of rotation, speeds and "in position" are available to the user, relieving the machine control system of positioning tasks.

EUCHNER positioning systems in combination with a PLC allow positioning processes that are not possible, or are limited, with a conventional angular position transducer.

48

Areas of application include all positioning tasks for a fixed number of positions on rotary or linear axes, while complying with the technical specification of the positioning systems. Communication can take place either directly with the PLC or with other suitable controllers. The positioning programs (angle tables), the location of the switching points for speed control and, in the PSU, the ramps and automatic control parameters, are created by the customer on a PC and transferred through a serial interface (RS 232) to the PSU/PSV. The PSV positioning system has only digital outputs. In the PSU, the additional analogue output (± 10 volts) is used for control and automatic position control of a servomotor, for example.

In the electronic Multiturn PSU-M and PSV-M, the required number of absolute revolutions is programmed by the customer. The revolutions are monitored and assigned by a microcontroller.

Features  Angular

position encoder and electronics in a single device  Machine control system is relieved of positioning tasks  Ideal price/performance ratio  Directional logic minimises down time  No mechanical zero point ad justment required  Custom parameters can be programmed on PC  High resolution (1440 or 4096 positions per revolution)

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

Controller

(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.

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 mo re than 180° 18 0° while power is absent.

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.

Programmable Cam Switch Programmable Electronic Cam Switch PNS 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.

54

The PNSWIN Interface

Advantages

The PNSWin graphical user interface makes it easy for the user to

The PNS provides the following advantages over mechanical cam controllers:

 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.

 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.

Incremental Encoders 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 converte d into two 90° phaseshifted 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 satisfied.
