These generated impulses can be used to control angular or linear movements, if they are associated with a rack or endless screws. The electrical signals during rotation can be elaborated by numerical controls (CNC), programmable logic controls (PLC), control systems, etc. The main applications of these transducers are as follows: machine tools, working of the material, robots, retroaction systems on motors, measurament and control apparatus. In ELTRA’s encoders the angular movement trasduction is carried out on the photoelectric scanning principle. The reading system is based on the rotation of a radial graduated disc formed by opaque windows alternated with transparent ones. This system is all illuminated in perpendicular way by an infrared light source, so the light projects the disk image on the receivers surface, which are covered by a grating called collimator, having the same step as the disk. The receivers work trasducing the light variations occuring with the disk shifting, converting them into their correspondig electrical variations. Electrical signal raised to generate the squared impulses without any disturbances must be electronically processed. The reading system is always carried out in differential mode comparing two different signals nearly identical, but out of phase for 180 electrical degrees to increase the quality and the stability of the output signals. The reading is made on the two signals difference, eliminating the disturbances defined "shifted common way" because they are overlapped in an equal way on every type of wave. Photo emitter Optical disc Photo receivers Incremental encoders The incremental encoder gives usually two types of squared waves that are out of phase for 90 electrical degrees, which are usually called channel A and channel B. The reading of only a channel gives the information in relation to the speed of rotation, while through the acquisition of second channel the sense of the rotation is given on the basis of the states sequence produced by the two signals. A further signal called Z or zero channel is also available, which gives the position of absolute zero on the encoder shaft. This signal is a squared impulse with the phase and the width centered on A channel. B A Z 2 Example of incremental windows A, B and Z on the optical disc The incremental encoder precision depends from mechanical and electrical factors among which, the error in the grating division, the disc eccentricity, the bearings eccentricity, the error introduced by the reading electronics and the innacurancy of optic. The unit of measurement, to define the encoder precision is the electronical degree, which determines the division of the impulse generated by the encoder, inf act 360 electrical degrees correspond to the mechanical rotation of the shaft which is necessary to carry out a complete cycle. To know how many mechanical degrees corresponds to electric 360° you need to apply the following formula: Rotation sense- CLOCKWISE 360° 180°± 25° max 90°± 35° max Values expressed in electrical degrees A B Electrical 360°= Mechanic 360° n° pulse / turn The error of encoder division is given from the maximum shifting shown in electrical degrees, of two consecutive surges. This error exists in any encoder and is due to the above mentioned factors. Graphic representation of the A, B and Z incremental signals . For Eltra encoders this error is included in electrical +/- 25° Max. (in whatever condition declared) which corresponds to a shifting +/- 7% from the nominal value. Regarding the shifting between the two channels shifted by electrical 90° nominally, it differs by electrical +/-35° max, corresponding to more or less the +/- 10%. Z Incremental encoder with integrated commutation phases More than the above mentioned traditional encoders there are also other ones making part of the same incremental family, but which integrates other electrical output signals. This is the case of the incremental encoders with integrated commutation signals which are usually used as retroaction on a motor. These supplementary signals carry out the simulation function for the hall phases generally present in the commutation motors (brushless type); they are usually made with magnetic sensors. In ELTRA’s encoders these commutation signals are optically generated and they are present in the form of three square waves that are shifted by electrical 120°. These signals are needed to the convertor that will pilot the motor in order to generate the correct phase voltages or the currents to supply the rotation. These commutation impulses can be repeated many times within one mechanical rotation because they depend directly to the number of poles in the connected motor, so we have phases of commutation for motors of 4, 6, or more poles. 90° Rotation sense- CLOCKWISE INCREMENTAL SIGNALS A B Z U V W 120° 360° Values expressed in electrical degrees COMMUTATION PHASES Graphic representation of A, B and Z incremental signals with commutation U,V and W.

To ensure good motor piloting performance the encoder retroaction must be able to supply a high number of impulses especially when the velocity rotation is low. The error refered to encoder/turn depends. the use of analogue signals allows to limit drastically the above mentioned inconveniences and to simulate efficiently an encoder of high impulses.CLOCKWISE Values represented in electrical degrees SIN COS Z Graphic representation of the sin. This encoder is used when one wants to increase the dynamic performance in comparison to other traditional systems. The use of the traditional incremental encoder with high impulses becomes problematic from many points of view.

This can be easily squared to supply an impulse of reference with a variable opening angle. it is also difficult transmitting and processing the digital signals when the motor rotates at high speeds (6000rpm). cos and Z sinusoidal signals.it E-mail:eltra@eltra. with the main difference that the output signals are not digital but analogue of sinusoidal form. the band-width necessary to the servomotor to treat the signal (for example an encoder of 10.it ELTRA reserves the right to make any modifications without prior notice SV008GB0803A The error of the deviation of the angle measured in comparison to the real one is generally produced by the above mentioned factors and is maintained within 10’. The fundamental data to define the precision of this encoder are the linearity of the single sinusoid (of the 2048 on turn) and the maximum deviation of any angle rotation in comparison to the real mechanical position. This happens thanks to the interpolation method of the sine and cosine analogue signals for the calculation of the rotation angle. It is easy to obtain a high multiplication of the base sinusoids by getting .ITALY . .

Generality As can be seen from the explicative drawing, the Eltra magnetic belt is composed essentially of three layers: 1 - A flexible magnetic belt made of plastic material. 2 - This is a magnetised steel belt with the characteristic of creating a shield against any external magnetic fields of a certain level; apart from this, as it is in contact (glued) to the upper plastic layer, it is essential for supplying the correct mechanical consistency to the magnetic belt. 3 - This last part of the belt is the least flexible part. It is in fact supplied separately (for transport and application reasons) and is glued to layer 1 by the user. This is a steel belt transparent to the magnetic flow, with the function of mechanically protecting the magnetic belt. 3 Various products 1 2 N.B.: To prevent damage from possible internal tensions in the magnetic belt, keep the band rolled up with the magnetic part facing outwards with a minimum internal diameter of 300 mm. Measures to adopt when applying the magnetic tape Pressure for fixing The magnetic belt is adhesive and it is therefore important that the contact with the surface to be glued is optimum for correct application. For this to take place, good pressure must be applied uniformly to guarantee perfect adhesion between the surfaces. Gluing temperature For the adhesive to adhere in an optimum way, it is preferable for the temperature of the material in which the magnetic belt is placed to be between 20° C and 37° C. Maximum adhesion is obtained after 72 hours at a temperature of 21° C. We recommend against applying the magnetic belt if the temperature of the gluing surface is lower than 10° C. Application materials For the magnetic belts to adhere correctly, they must be placed in dry, smooth and clean places. The surfaces should be cleaned with a solution of alcohol and water at 50% or heptane. In the case of materials such as brass, copper etc. the surface must be protected to prevent possible oxidisation.

The open collector variant is different for the lack of the pull-up resistor. freeing. Infact the major limitations of the npn NPN D or pnp electronics. so that the output is of low impedance. is of the pull-down type connected. The manner is influenced in proportional way by the increase of the cable length. thus the ideal application should keep these considerations in mind. PNP and PNP open collector + Vdc PNP Out 4. in comparison to the preceeding logics. can depend on the use of the resistor 22 W which presents a much higher impedance than a transistor in Out closing. The levels of signal saturation are contained. if present. To overcome these inconveniences in the push-pull PNP type elctronics. if crossed by a superior current to the one prearranged. The Eltra encoders can be equipped with these two levels of protection against short circuits. which can bring about a progressive delay in the components to be protected.54R 0 Vdc Protection for output stages Exist two different mode to protect an electronic circuit from short circuit: the first uses passive element (fuses.) and the other uses active parts (transistor.

The use limitations of this protection are to be found in the speed of the intervention which is rather low. Passive protection The passive solution is the cheapest solution and is direct to cover accidental short circuits. increases its resitance to limit the increase of the current itself. effective for a limited number of short circuits and is available for the npn. non linear resistors.

It is only available for line-driver and push-pull electronics. which is the mass of the system. pnp and push-pull electronics. it is insensitive to common way disturbances. This characteristic allows at the protection to be very efficient and fast in the intervention on repetitive and permanent short circuits and it is specifically indicated for heavy use. to be balanced by the input resistance of the receiver that must have an equal load impedance. created on purpose. or rather from the differences of the voltages present on the complementary channels of trasmission and. Active protection The second solution is based on an integrated electronic circuit on the output stage.This electronics presents an impedance of typical line of about 120 Ohm. therefore. these interferences are known as “common way disturbances”. DIFFERENTIAL electronics type It is used in the sinusoidal line-driver analogic encoders where is necessary a transmission of a signal without disturbances. etc. Like to the line-driver electronics. further more power supplies up to 24 Vdc are available where the hard conditions of use need them (long cables. etc.This type of transmission is used in 5 Vdc systems and is also known as RS422 compatible. so the disturbances are L limited (the disturbances are caused to cables or adjacent Out apparatus). as their generation is refered to a common point. which happen with limited repetitions. etc. Thermal protection °C NPN D PTC +Vdc Out +°C PNP D D 0V + Vdc D Out Out 0 Vdc 64 .
