2 Note for CAD users! CAD data available scale 1:1 as DWG, DXF, IGES on request conformity / EMV Requirements Absolute encoders form part of a fully independent system, such as a machine which is subjected to very high safety standards. The SIKO absolute encoders and positioning systems are in compliance with the European EMV directive 89/6/EU. The European standards EN and EN are applicable to these devices. Tests were based on the classification typical industrial environment. Please observe carefully the appropriate notes in the user documentation before mounting the absolute encoders, especially with respect to their insulation and screening requirements. The characteristic electrical values such as voltage ratings apply for plugs and cable lengths of 2 m.

3 Absolute encoders produced by SIKO Absolute encoders provide absolute and direct measurement of angles of rotation and distances. Linear motion is converted into rotary motion via toothed belts, pinion gearings or cable control. Absolute encoders may find their fields of application in the wood working, metal, printing or packaging industries to measure the movements of robot arms, movement along linear axes, changes in angle or are used in synchronizing (correcting) control. Single-turn, Multi-turn SIKO absolute encoders are supplied in single-turn and multi-turn version, in the case of single-turn encoders, a code disc measures up to 8192 (1 bit) steps per revolution (60 ). After each complete revolution, the coding starts again at its initial value. Additionally, multi-turn encoders are equipped with an encoded stepdown gearing which measures and codes up to 4096 (12 bit) steps per revolution. No need to move to a calibration point after reactivating the voltage supply. Cost saving, because no counter subassemblies are needed. No errors in counting. Direct processing of the bit code by the control unit. Field bus compatible Robust assembly, high shock load tolerance Blind hollow shaft up to ø 20 mm Absolute encoder WK 50/1 Multi-turn with hollow shaft The total resolution can be calculated Code disc as follows: : 1 Bit (single-turn) + 12 Bit (revolutions) = 25 Bit Since the number of measuring steps is very high (> million), very long distances can be divided into small steps. 1 Optoelectronic Measuring Principle In comparison to other codes, the Gray code only changes one bit per step (single step code) to prevent reading errors. When the absolute encoder and/or code discs rotate, an optical array scans the code. After one complete turn, the coding starts anew (single-turn) and the sequence is repeated. Optical absolute encoders with a mechanical multi-turn component are equipped with a code disc for measuring 60 of rotation and with additional discs for measuring further revolutions. GRAY Bit pattern LSB BINARY Bit pattern LSB Information Information 2 Principle of a mechanical multi-turn encoder 1. single-turn-disc multi-turn components with stepdown gearing 4 5 Principle of operation of optoelectronic scanning with absolute encoders Gray code Binary code Gray-Excess-Binary codes Gray codes are used when the desired number of steps per revolution is an integer power of 2, e.g = 1024 steps per revolution. With Gray-Excess-Binary codes, any integer number of steps, e.g. 60, 1000, can be measured. In this case the coding of the next larger integer power of 2 is partly used, where the codes at the upper and lower ends are symmetrically capped and the surplus codes not used. Example: 1000 = 1024 (2 10 ) - 24 Capped at each end by 24/2 = 12 This results in the special condition that the output codes do not start with 0 and the end value is not identical to the required number of steps per revolution. Example: 1000 steps/revolution (e.g. degrees) Start code 12 (represents 0 ) End code 1011 (represents 59 ) Capped codes are only available on single-turn absolute encoders. SIKO Absolute Encoders

27 Data Transfer / Interface Parallel Interface Parallel or serial transmission of measurement data to the control unit. Parallel interfaces allow simultaneous parallel access of the output data. There are as many data transmission lines necessary as there are tracks on the code-disc. Additionally, one line is required for the voltage supply and one line as a ground cable. Advantages of parallel interface: High data transfer rates and simple connection to digital input devices and counters. Easy maintenance due to easy verification of the independent lines.

Advantages of serial interface: low cabling requirements suitable for long transmission distances field bus compatible Synchronous Serial Interfaces (SSI): Absolute encoders with the interfaces RS422 and SSI provide the following advantages: Only four transmission lines are required for the pulse sequence and data transmission, regardless of the absolute encoder resolution. Accurate data recording by application of one-step Gray code Total electrical isolation by use of an optical coupler between absolute encoder and control unit. Easy conversion of Gray code into Binary code. The clock signals of the control unit synchronize the data transfer between encoder and the control unit. Baud rates can be in the range of 62,5 khz to 1 MHz, depending on the cable length. In applications where several absolute encoders are used, simultaneous recording of all encoder information with no additional line required.

28 Data Transfer / Interface Processing system of synchronous serial data transmission: Continual scanning of the position of the code disc(s). The required data is available at the data input of the parallel/serial (P/S) converter. The control unit calls up the measured value by sending a special pulse sequence to the encoder (the number of bits is dependent of the data to be transferred). The first High-Low transition (point 1 in the pulse diagram fig. ) triggers the monoflop i.e. the value available at the P/S-converter is retrieved. (the Low level of the monoflop prevents more values from being retrieved by the converter during data transfer). The first Low-High-transition (point 2 fig. ) triggers the transfer of the Gray code bit with the highest value. Each following Low-High-transition of the pulse sequence triggers the transition of the bit with the next lower value. The pulses continuously retrigger the monoflop, so it remains Low and no further data will be retrieved. The bit sequence will be halted by stopping the pulses when the bit with the lowest value has been transmitted to the control unit (point fig. ). No further triggering of the monoflop. After the period tm (point 4 fig. ), the output value changes back to the High level and thus enables the P/S transducer to call in new parallel data. pluse Takt Daten data seriell serial monoflop Monoflop P/S Daten data parallel Takt pluse T 4 m 1 m m + 1 m = stored parallel information tv = delay time for the 1st pulse max. 540 ns, for all further max. 60 ns Gn = highest bit value in Gray code Fig. : Pulse diagram for data transfer Taktfolge clock pluse rate tv Gn Gn 1 G 1 G 0 m clock Taktpause pluse break (Tp) p) tm T = period duration of pulse signal G0 = lowest bit value in Gray code tm = monoflop-time15 µs to 25 µs Tp = clock pulse break > 5 µs Fig. 4: Clock pulse rate for synchonous serial data transfer Taktfolge clock pluse rate Recommended baud rates for the data transfer: cable length Baud rate m KHz < 50 < 400 < 100 < 00 < 200 < 200 < 400 < 100 (Cables must be twisted pairs and screened.)

29 Data Transfer / Interface Interface InterBus-S The InterBus-S has been developed with the aim of supplying SPS users with a fast field bus for digital data input and output while reducing the cabling cost. The InterBus-S ring-topology is designed in such a way that reciprocal data transmission lines are combined and integrated in one physical line. Basically, a distinction can be made between (distance-) and periphery busses. Note that Inter- Bus-S is an real time bus for the sensor-actor-level which operates with small overhead and transmits up to 4 bytes of data per user for the maximum total number of 256 users. Interface InterBus-S Features low cabling and installation cost low susceptibility to interference easy planning, installation and start-up high efficiency simultaneous recording of all user data and subsequent data transfer easy determination of responding time which is only dependent on overall capacity constant scanning rate for desired value/actual value equal priority of all users complex diagnostic software no parameter assignment before operation data integrity ensured by 16-bit CR-check which is processed each time data is transmitted according to the CCITpolynomial. Run Operation (InterBus-S) The InterBus-S consists of the following elements: Field bus RS485 transfer of difference in voltage Cable length between two bus terminals: max. 400 m Entire cable length of field bus: max. 1 km A maximum of 64 bus terminals/modules may be connected directly to the field bus Periphery bus 5 V potential interface entire cable length of periphery bus: max. 10 m a maximum of 8 modules may be connected Installation field bus only for modules with protection IP 65 RS485 transfer of difference in voltage Entire cable length: max. 50 m Connectors: bus terminal or passive T-distributor Electrical isolation of each user the 24 V supply may be applied at the bus line or at the T- distributor the data transmission rate amounts to 500 kbit/s Principle of protocol ENCOM-web group Ein Summentelegrammrahmen; ein Telegrammrahmen für alle Teilnehmer An additional telegram frame; a telegram frame for all users Data Data Data Data Data Data Data Header Gerät Unit 1 Gerät Unit 2 Gerät Unit Gerät Unit 4 Gerät Unit n-1 Gerät Unit n FCS End Bus terminal - repeater function Busklemme - (de-) activates alternative - Repeaterfunktion path for insulation of - schaltet alternative Wege errors zur Fehlerisolierung and system configuration und Systemkonfiguration Anschaltbaugruppe Activating Assembly Busmaster Field Fernbus 1 km optimised for cylcle optimiert für zyklische Prozeßdaten process data cycle Zykluszeit time answering Antwortzeit time t Summenrahmen additional frame Periphery Peripheriebus 8 Teilnehmer 8 partner mm Sensor 1 Sensor 2 Aktor Sensor 4 Aktor 8 Sensor 9 Aktor 40 Field Fernbus 400 m Rahmendaten frame data Nutzdaten used data 400 m Installationsfernbus field 50 m Fig. 7: Protocol InterBus-S Fig. 6: Principle InterBus-S SIKO Absolute Encoders 29

30 Data Transfer / Interface The following ENCOM encoder types are applied: Type 2 (K2): 2 bit process data binary ranged right readable only no control or status bits The Fraunhofer-Institute for Information- und dataprocessing (IIBT; information and data processing) located in Karlsruhe performs conformity tests of InterBus-S encoders. A certifcate guarantees the reliable operation of the field bus devices tested. Type (K): 2 bit process data coded in accordance with manufacturer s details ranged right 7 status and control bits Options (for WKS and WKM ) Latch function The latch function offers the facility to store the current output value of the absolute encoder until the latch signal is deactivated. At high speeds, the data from the absolute encoder changes equally fast, in many cases too fast to be assimilated by the control unit. By using the latch function, the control unit can freeze the output value until the read sequence has been completed. This ensures that the data read is not corrupted. Control signals Function Level Status Latch 0 ( 8 V) free running 1 (+ 10 V) stored Tri-State 0 ( 8 V) disabled (high impendance) 1 (+ 10 V) enabled (active) Tri-State function The tri-state function allows the outputs of the absolute encoder to be deactivated. When switched off the outputs maintain a high impedance. Several absolute encoders may be wired in parallel on a bus ending in a single control unit. The control unit calls on the individual encoders (multiplexes) by activating the appropriate tri-state input. The activated encoder may then send it s data to the control unit to be read.

31 Options (for WKS and WKM ) Electronic Correction and Zeroing The electronic correction is achieved by bit or decade setting of the programming switches. By setting the appropriate correction values, the information output by the absolute encoder can be adjusted to the values read from the encoder code wheels. This enables the output value to be set to zero (zeroing). The correction/zeroing is activated by an exterior electrical signal. The programming switches are placed under a sealed cover (IP65) on the rear of the encoder. Due to their dimensions, encoders with electronic correction are only available with cable outlets. Only available for the series WK...65! Parity Bit (parity) This additional output, which provides an odd or even parity bit, is available as an option. Strobe signal An additional strobe signal can be used to synchronize the control unit and absolute encoder. As the requirements of the control unit can vary according to type, there can be no universal solution. Strobe LSB Fig. 10: Principle strobe signal Appendix (standard with WKS and WKM ) Complement function The complement function may be used to reverse the direction of the encoder electronically. With constant mechanical direction of rotation the level of the complement function changes the counting direction of the output codes. Control signals Function Level Status Complement 0 ( 8 V) I clockwise increasing 1 (+ 10 V) E counter-clockwise increasing Ascending codes are output in each case with: status I, clockwise rotation of the shaft status E, counter-clockwise rotation of the shaft SIKO Absolute Encoders 1
