2 INCREMENTAL ENCODER GENERAL DESCRIPTION Working principle An encoder is a rotational transducer converting an angular movement into a series of electrical digital pulses. If associated to racks or endless screws, these generated pulses can be used to control angular or linear movements. During rotation, electrical signals can be elaborated by numerical controls (CNC), programmable logic controls (PLC), control systems, etc. Main applications of these transducers are: machinery, robots, motor feedback, measure and control devices. In Eltra s encoders the angular movement transduction is based on the photoelectric scanning principle. The reading system is based on the rotation of the radial graduated disk formed by opaque windows and transparent ones alternated. The system is perpendicularly illuminated by an infrared light source. The light projects the disk image on the receivers surface which are covered by a grating called collimator having the same disk steps. The receivers trasduce the light variation occurring with the disk shifting, converting them into their corresponding electrical variations. Electrical signals raised to generate squared pulses without any interference must be electronically processed. The reading system is always carried out in differential modality, in order to compare different signals nearly identical but out of phase for 180 electrical degrees. That in order to increase quality and stability of output signals. The reading is designed comparing the difference between the two channels eliminating the disturb note as shifted common way because signals are overlapped in equal way on every kind of wave. Photo receivers Optical disc Photo emitter Incremental encoders The incremental encoder usually gives two types of squared waves out of phase for 90 electrical degrees. They are usually called channel A and B. The first channel gives information about the rotation speed while the second, basing on the states sequence produced by the two signals, provides the sense of rotation. A further signals, called or zero channel, is also available. It gives the absolute zero position of the encoder shaft. This signal is a squared impulse with the phase and the width centred on A channel. 2

3 The incremental encoder precision depends on mechanical and electrical factors. These errors could be: grating division, disk eccentricity, bearings eccentricity, electronic reading and optic inaccuracy. The measurement unit to define encoder precision is the electrical degree. It determinates the division of the impulse generated by the encoder: 360 electric degrees correspond to the mechanical rotation of the shaft which is necessary to carry out a complete cycle. To know how many mechanical degrees correspond to electrical 360 the following formula has to be applied: Clockwise rotation sense Values expressed in electrical degrees Mechanic 360 Electrical 360 = n pulse / turn The encoder division error is given from the maximum shifting shown in the electrical degrees of two consecutive surges. This error exists in any encoder and is due to the above mentioned factors. For Eltra s encoders this error is included in electrical +/- 25 Max in whatever allowed condition, which corresponds to a shifting of +/- 7 % from the nominal value. Regarding the 90 electrical degrees shifting between the two channels, it differs by +/- 35 electrical degrees Max. It corresponds to +/- 10 %. Graphic representation of the A, B and incremental signals. Incremental encoder with integrated commutation phases In addition to the above mentioned encoders, there are others which integrate additional electrical output signals. These are the incremental encoders with integrated commutation signals, used as motor feedback. These additional signals simulate the Hall phases generally present in the commutation motors (brushless type) and usually designed with magnetic sensors. In Eltra s encoders these commutation signals are optically generated and presented as three squared waves, shifted by 120 electrical degrees. These signals will be used by the driver control to the motor in order to generate the correct voltages phase to determinate the correct rotation. These commutation pulses can be repeated many times within one mechanical rotation because they directly depend on the poles number in the connected motor. So we have commutation phases for motors of 4, 6 or more poles.

63 Tape composition As shown below, the Eltra magnetic tape is composed by three layers: 1 - A fl exible magnetic tape made of plastic material 2 - A magnetised steel tape used to create a shield against any external magnetic disturb. Although, it s glued to the upper plastic layer in order to supply the correct mechanical consistency to the magnetic tape. 3 - The third part is the most rigid one and therefore is supplied separately due to transport and application needs. It must be stick to layer 1 by the user. The steel tape is magnetically neutral and employed to mechanically protect the magnetic tape NOTE: To prevent damage from possible internal tensions in the magnetic tape, keep the tape rolled up with the magnetic part facing outwards with a minimum internal diameter of 300 mm. Installation measures of the magnetic tape Fixing pressure The magnetic tape is adhesive. Therefore, it is important an optimum contact between surfaces for a correct application. A good pressure must be uniformly applied to guarantee a perfect result. Gluing temperature In order to guarantee an optimum adhesion it is preferable a surface temperature between 20 and 37 C. Maximum adhesion is obtained after 72 hours at a temperature of 21 C. We suggest to avoid applying the magnetic tape at a lower than 10 C surface temperature. Application materials For a correct adhesion the magnetic tape must be placed in dry, smooth and clean places. The surface must be cleaned with an alcohol-water solution at 50% or heptane. For appliances on brass, copper etc. the surface must be protected to prevent possible oxidation.

For instance, it happens to have an encoder with a 5 Vdc output and a control accepting only 24 Vdc data. It may also happen to use an encoder connected with a controller at the same voltage, but having different electronics. It can solve a wide range of problems: check the ordering code in the back page to find further information. On the board there can be present up to two different voltages and it must be supplied through the X4 connector with the higher voltage used. Moreover, it is possible to obtain up to eight outputs by assembling more than one board reducing drastically wiring by mounting boards in a single support. In this case, the ordering code will contain information about all outputs. For example, a board with a 5 Vdc NPN and eight outputs line drivers at 5 Vdc has the following ordering code EMB5N5L5L5L5L5L5L5L5L. The following may give an example of a typical EMB application: an encoder with 5 Vdc LINE DRIVER output has to be connected to a PUSH-PULL 24 Vdc input and also to an instrument having a LINE DRIVER 5 Vdc input. The board to order has the following code: EMB5L24P5L where 5L indicates a 5 Vdc LINE DRIVER input on X1 connector, 24P indicates the 24 Vdc PUSH-PULL output on the X2 connector, and the last 5L indicates the 5 Vdc LINE DRIVER output on the X3 connector. The input voltage of this board is the 24 Vdc one, because it is the highest used, and it will be supplied from the X4 connector. 66

The output signal is selected by opportunately suppling the two inputs, IN1 and IN2, according to the working diagram (see back side). Output and encoder type to be connected have to be within the range described in the ordering code. All electronic types of the connected encoders have to be the same. Moreover, the EMD supplies three contacts normally open switching to close when the respective input is selected. In order to better understand the use of this board the following example is provided. We would like to realize a device reading three encoders input (or other sensors with compatible characteristics), in a sequential way. Encoders have to be choosen featuring the same electronics output, for example 5 Vdc line-driver. Instead, the device can acquire data with another electronic type; for example 24 Vdc push-pull. In this case the EMD board realizes the commutation function of the connected encoders and adapts the electronics of those with the one required from the instrument. The ordering code will be: EMD5L8/249 5L indicates that inputs are 5 Vdc line-driver. 8/24P indicates that the output is with push-pull electronics and with an input voltage from 8 to 24 Vdc. The board input voltage has to be the highest between the requested: in this case 8/24 Vdc. The encoder commutation happens through a logic type signal at the IN1 and IN2 inputs on the Xn terminal board. The logic level 1 is obtained by connecting the above mentioned inputs to a voltage included between +5 and +24 Vdc. Instead, for the 0 level, the voltage must be between 0 and +3 Vdc. The combination of the logic levels at IN1 and IN2 configurates the terminal board of output in 4 different mode as described in the table in the following page. 68

70 PRECISION ASTIC COUPLINGS Elastic Couplings Ordering Code SPECIAL PRODUCTS TRA elastic precision couplings are essential parts for the transmission of rotational motion to the encoder shaft. Couplings are designed in aluminium alloy (type D11S A.A 2011) and are composed by a cylindrical body on which there is an helicoidal groove. Main characteristics are: - torsional rigidity - ability to support slight shaft misadjustments - ability to absorbe small axial shift of the shaft. TRA elastic couplings have also a perfect balancing of the rotating body. They don t have critical points subjects to breakage and are completely frictionless. Moreover, they perfectly transmit the rotation motion, even in case of axial misadjustment and misalignment. Our coupling do not require any type of maintenance. The internal drain allows the coupling between the shafts from a minimum of 0.5mm to a maximum of 6.12mm (note F quota). NOTE: Elastic Coupling can be supplied with different coupling diameters. Eg: d1=8mm, d2=10mm. In this case the identifi cation code should be: G25A8/10.

72 OUTPUT CONFIGURATIONS AND CONNECTIONS NPN and NPN OPEN COLLECTOR electronic NPN OPEN COLLECTOR It is composed only by an NPN transistor and a pullup resistor used to match the output voltage to the power supply when the transistor is quiscent. From the electrical point of view it is similar to TTL type logic and so it is considered compatible. If used correctly, it shows low saturation levels at 0 Vdc and close to 0 at the positive. It is proportionally influenced by the cable length, pulses frequency and by the load. Please consider these specs for a proper use. The open collector variant is different for the lack of the pull-up resistor, freeing in such way the transistor collector from the tie of the encoder power supply allowing to obtain signals with different voltage. NPN ENCODER NPN Power supply Output signal GND Power supply R load RECEIVER Power supply Power supply R load Output signal LOAD NPN GND ENCODER RECEIVER OUTPUT CONFIGURATIONS PNP and PNP OPEN COLLECTOR electronic Main characteristics and limitations are the same as for NPN electronics. Main difference is the transistor, which is of PNP type and is constrained to the positive. The resitor, if present, is a pull-down one. Therefore, it is connected between the output and zero Vdc.

73 PUSH-PULL PUSH-PULL electronic NPN PNP ENCODER R load Power supply Output signal GND LOAD Power supply RECEIVER Electronic featuring high performances. NPN or PNP major limitations are caused by the resistor, which works with a much higher impedance than a transistor. To overcome this issue, push-pull electronic uses a complementary transistor, so the impedance is lower for commutation to positive and to zero. This solution increases frequency performances allowing longer cable connections and an optimal data trasmission even at high working speed. Saturation signals are low but sometimes higher than in NPN and PNP electronics. Anyway, PUSH-PULL electronics is in any case indifferently applicable instead of NPN or PNP. LINE DRIVER LINE DRIVER electronic ENCODER Power supply output output GND PROTECTIONS + C NPN PNP ENCODER ENCODER Power supply output output GND PTC + C Power supply Output signal GND Power supply R load RECEIVER Power supply LOAD RECEIVER Power supply R load RECEIVER LINE DRIVER is used when operating enviroments are particulary exposed to electrical disturbances or when the encoder is quite far from the receiver system. Data trasmission and receiving work on two complementary channels so disturbances are limited (they usually come from other cables or close machinery). These interferences are known as «common way disturbances» as their generation is due to a common point: the system mass. Instead, in LINE-DRIVER transmetted and received signals work in «differential» way. In other words, it works basing the communication on voltage differences between complementary channels. Therefore it is not effective to common way disturbances. This type of transmission is used in 5 Vdc systems and it is also known as RS422 compatible. It is available with power supplies up to 24 Vdc Protection for output stages Two different kind of electronic protection against short circuits might be used: the passive one (using fuses, no linear resistors, etc.) and active one (using transistors). Eltra s encoders can be equipped with both type of protection against short circuits Passive protection Passive solution is the cheapest one. It is used to avoid accidental short circuits, which rarely happens. The component which carries out the protection is called PTC. It is a resistor that, if crossed by a voltage exceeding the supposed one, increases its resistance to limit electricity exceedance. Limitations of this kind of protection concern the low reacting speed, which may progressively stress the components under protection. Therefore, this protection is effective against a limited number of short circuits and it is available only for NPN, PNP, and PUSH- PULL electronics. Active protection This solution is based on a circuit integrated in the electronic output which costantly controls the temperature reached by the element to be protected. In this way, protection is very effective and the reacting speed very high. Moreover, it ensures a constant protection against repetitive and permanent short circuits, that is why is strongly suggested for heavy usages. It is available only for LINE-DRIVER and PUSH-PULL electronics.
