As a systems supplier, SEW offers a comprehensive range of encoder systems.Various mounting devices are available to connect non-SEW encoders to SEW motors.Proximity sensors represent an inexpensive and easy-to-fit solution, if all that is required is theinformation about whether or not the drive is turning and in which direction.Encoders Absolute encoders and resolvers Encoder systems for asynchronous AC motors Encoder systems for synchronous motors1SEW encoder systems for asynchronous AC motors:•Incremental encoders-for5V DC supply voltage and with 5 V TTL signal level according to RS-422recommended for operation with the MOVITRAC® 31C frequency inverter-for24V DC supply voltage and with high-resolution sinusoidal signal levelrecommended for operation with the MOVIDRIVE® drive inverter-for24V DC supply voltage and with 5 V TTL signal level according to RS-422-for24V DC supply voltage and with 24V HTL signal level•Absolute encoder-for15V DC supply voltage and with MSSI interface-for24V DC supply voltage and with MSSI interface and two sinusoidal tracks•Proximity sensors-with six pulses per revolution-with A track or A+B track•Mounting devices for non-SEW encoders-mounting of spread shaft-mounting of full shaft with couplingSEW encoder systems for asynchronous servomotors:•Incremental encoders-for24V DC supply voltage and with high-resolution sinusoidal signal levelstandard feature in CT/CV motors-for24V DC supply voltage and with 5 V TTL signal level according to RS-422•Absolute encoder-for24V DC supply voltage and with MSSI interface and two sinusoidal tracksSEW encoder systems for synchronous servomotors:•Resolverstandard with synchronous servomotors for speed control•Absolute encoder15/24 V DC supply voltage with MSSI interfaceEncoder selection based on setting range:•Setting range up to 1:3000-with asynchronous AC motors → encoder with TTL signals and1024 increments/revolution-with synchronous motors → built-in resolver•Setting range up to 1:5000-with asynchronous AC motors → encoder with high-resolution sinusoidal signal levels-with asynchronous servomotors → encoder with high-resolution sinusoidal signal levelsSEW encoder systems56SEW encoder systems 1All encoder systems at a glance: *recommended encoder for operation with MOVITRAC ® 31C **recommended encoder for operation with MOVIDRIVE ® Mounting devices for non-SEW encoders Name For SEW motor size Type of encoder Shaft Specification Supply Signal ES1T*CT/DT 71...100Encoder Spread shaft - 5 V DC controlled 5 V DC TTL RS-422ES1S**24 V DC 1 V SS sin/cos ES1C 24 V DC HTL ES1R 5 V DC TTL RS-422ES2T*CV/DV 112...132S 5 V DC controlled 5 V DC TTL RS-422ES2S**24 V DC 1 V SS sin/cos ES2C 24 V DC HTL ES2R 5 V DC TTL RS-422EV1T*CT/CV71...180DT/DV71...225Solid shaft 5 V DC controlled 5 V DC TTL RS-422EV1S**24 V DC 1 V SS sin/cos EV1C 24 V DC HTL EV1R 5 V DC TTL RS-422NV16DT/DV 71...132S Proximity sensor Solid shaft A track 24 V DC 6 pulses/revolu-tion, NO contact NV26A+B track AV1Y DS56DY71...112CT/CV71...180DT/DV71...225Absolute encoder Solid shaft -15/24 V DC MSSI interface and 1 V SS sin/cos Name For SEW motor size Type of encoder Shaft Specification Supply Signal ES1A DT71...100Non-SEW encoder Spread shaft -Configured as mounting device ES2A DV112...132S EV1A DT/DV71...225Solid shaft AV1A DS56, DY71...112Solid shaft XV1A DT/DV71...225Solid shaftSEW encoder systems722Technical Data2.1Technical descriptionThis chapter explains the various types of signals, signal tracks and signal levels. The signal tracks are represented in the form of timing diagrams.Encoders have a sturdy light metal housing and generously sized precision ball bearings. Their solid metal housing protects the encoders against interference, which lends them a high degree of electromagnetic compatibility.2.1.1Incremental encoders with TTL and HTL signalsEncoders convert the angle of rotation input parameter into a number of electrical pulses. This is performed by means of an incremental disc incorporating radial slits permitting the passage of light. These slits are scanned by opto-electronic means. The number of slits defines the resolution (pulses/revolution).Signal tracks:SEW encoders are encoders with two tracks and one zero pulse track, which results in six tracks due to negation. Two light barriers are arranged at right angles to one another in the encoder. They supply two pulse sequences on tracks A (K1) and B (K2). Track A (K1) is 90° ahead of B (K2) when the encoder is turning clockwise (to the right as viewed looking onto the motor shaft, the “A” side).This phase relationship is used for determining the direction of rotation of the motor. The zero pulse (one pulse per revolution) is sensed by a third light barrier and made available on track C (K0) as a reference signal. With TTL encoders, tracks A (K1), B (K2) and C (K0) are negated in the encoder and made available on tracks A (K1), B (K2) and C (K0) as negated signals.01877AXXFig. 3: TTL signals with zero track and negated signalsHTL signals with zero track, but without negated signals 90°90°180°360°A (K1)A K1()B (K2)B K2()C (K0)C K0()8SEW encoder systems 2Signal levels:•TTL (T ransistor T ransistor L ogic) version The signal levels are V low ≤ 0.5 V and V high ≥ 2.5 V. The TTL signals are transmitted symmetri-cally and evaluated differentially. This design makes them resistant to asymmetrical interference and ensures good EMC behavior. The signal is transmitted in accordance with the RS-422 inter-face standard.Units with a 5 V DC encoder supply voltage, e.g. MOVITRAC ® 31C, allow the user to measure the actual supply voltage at the encoder via sensor leads. The supply voltage is corrected to 5 V DC and compensates for the voltage drop along the supply cable to the encoder. Encoders with 24 V DC supply voltage do not require any supply voltage compensation and, thus, no sensor leads.The maximum permissible distance between encoder and inverter is limited by the maximum pulse frequency of the encoder signals. SEW permits a maximum distance between encoder and inverter of 330 ft. (100 m).02542AEN Fig. 4: View of TTL signal levels •HTL (H igh-voltage T ransistor L ogic) version The signal levels are V low ≤ 3 V and V high ≥ V B minus 3.5 V. The HTL encoder is evaluated without the negated tracks; the signals cannot be evaluated differentially. The HTL signals are, therefore, suscep-tible to asymmetric interferences affecting the EMC behavior.V B is the encoder supply voltage in the range of 10 to 30 V DC , with 24 V DC +/- 20% being the most common value. HTL encoders do not require any supply voltage compensation and, thus, no sensor leads. The large voltage range between V high -V Low results in a high current consumption. A fact that has to be taken into consideration when planning the encoder supply.The maximum permissible distance between encoder and inverter is limited by the maximum pulse frequency of the encoder signals. SEW permits a maximum distance between encoder and inverter of 330 ft. (100 m).02543AEN Fig. 5: View of HTL signal levels 552.52.50.50.500TTL K K V [V ]DC "1" range "1" range "0" range "0" range V [V ]DC 2420.503HTL K V [V ]DC "1" range "0" rangeSEW encoder systems922.1.2Incremental encoders with high-resolution sin/cos signalsEncoders with high-resolution sin/cos signals are referred to as sine encoders. They provide two sine signals offset by 90°. The zero passages and the amplitudes (arc tan) of the sine/cosine waves are evaluated. This means the speed can be determined with a very high resolution. This encoder is suitable for drives which are operated with a wide setting range in conjunction with the require-ment to move smoothly at low speed.Signal tracks:SEW sinusoidal encoders are also dual-track encoders with a zero pulse and negated signals,resulting in six tracks. The 90° offset sine signals are on track A (K1) and B (K2). One sine half-wave per revolution is provided at track C (K0) as the zero pulse. Tracks A (K1), B (K2) and C (K0)are negated in the encoder and made available on tracks A (K1), B (K2) and C (K0) as negated sig-nals.01917AXXFig. 6: sin/cos signal s with zero track and negated tracksSignal levels:•The sine/cosine signals are superimposed on a DC voltage of 2.5 V. They have a peak-to-peak voltage of V SS = 1 V. This arrangement avoids voltage zero during signal transmission. The sine/cosine signals are transmitted symmetrically and evaluated differentially. This design makes them resistant to asymmetrical interference and ensures good EMC behavior. The signal is transmitted in accordance with the RS-422 interface standard. The supply voltage is 24 V DC .Sine encoders do not require any supply voltage compensation and, thus, no sensor leads.The maximum permissible distance between encoder and inverter is limited by the maximum pulse frequency of the encoder signals.

This code disc is scanned by opto-electronic means. Every angle position has a unique code pattern assigned to it. The absolute position of the motor shaft is determined using this code pattern. The special feature of Gray Code is that only one bit changes with the transition from one resolvable angle stepto the next. This means the possible reading error is max. 1 bit.01927AXX Fig. 7: Code disc with Gray Code Multi-turn:In addition to the code disc for sensing the angle position, multi-turn absolute encoders have addi-tional code discs for absolute sensing of the number of revolutions. These code discs are only sep-arated from each other by one gear unit stage with the reduction i = 16. With three additonal code discs (number usually installed), 16 x 16 x 16 = 4096 revolutions can be resolved absolutely.02383AEN Fig. 8: Arrangement of code discs A single-turn absolute encoder with 12 bit resolution requires 12 pulses to display the 4096 mea-suring steps per revolution. A multi-turn absolute encoder with three additional code discs requires 12 additional pulses to display the 4096 distinguishable revolutions.Single-turn evaluation Pulse 123456789101112Data 20 21 22 23 24 25 26 27 28 29 210 211 Measuring steps per revolution in addition with multi-turn evaluation Pulse 131415161718192021222324Data 20 21 22 23 24 25 26 27 28 29 210 211 distinguishable revolutions i = 16i = 16i = 16Code discs for sensing the number of revolutions Code disc for sensing of angle position Decimal Gray Code Decimal Gray Code 00000811001000191101200111011113001011111040110121010501111310116010114100170100151000Signal outputs:Every scanned code pattern is a parallel data package and is read by a parallel/serial converter. The inverter must request the position value with a defined pulse sequence in order to transmit a posi-tion value from the encoder to the inverter. The pulse sequence starts by converting the current parallel data package and transmitting it to the inverter. The input of the parallel/serial converter is inhibited by the monoflop for the duration of the pulse sequence.01923AENFig. 9: Signal conditioning in absolute encoders with SSI interfaceIn addition to the absolute angle position, the SEW absolute encoders generate the incremental encoder signals A (K1), A (K1), B (K2)und B (K2) and make them available as 1 V SS sine signals.Signal transmission:SEW absolute encoders have an SSI interface (SSI = S ynchronous S erial I nterface) to transmit the absolute value signals and a RS-485 interface for transmission of the 1 V SS sine signals.01928AENFig. 10: Pulse diagram of data transmission via SSI interfaceInverterCycleSerialdataParallel dataCode discDriver InputcircuitSchmitt trigger P a r a l le l /S e r ialconverterPhoto transmitter Photo receiver MonoflopShift SI SOCycleSerialdataMonoflop P/SParalleldata2.1.4ResolverThe resolver determines the absolute position of the motor shaft. It consists of a rotor coil and two stator windings offset by 90° in relation to each other. It operates according to the principle of the rotary transformer. Furthermore, the resolver has one auxiliary winding each in the stator and on the rotor in order to transfer the supply voltage to the rotor without brushes. Both rotor windings are electrically connected.01931AEN Fig. 11: Schematic diagram and equivalent circuit diagram of the resolverSignal outputs:Voltages of varying magnitudes are induced in the stator windings depending on the rotor position. Voltages V1 and V2 on the two stator windings are modulated by the supply voltage through induc-tion. They possess sinusoidal envelopes. The two envelopes are electrically offset by 90° from one another and are evaluated in the inverter for zero passage and amplitude. This enables the rotor position, speed and direction of rotation to be established.00058AXX Fig. 12: Output voltages V1 and V2 of the resolverSignal level:The amplitude of the envelope depends on the r.m.s. value and frequency of the supply voltage V e.γS1S3S4S2R1R2V1stator statorrotorV2V RV estatorstationaryrotating stationarystationaryV2VRV1V1V22.1.5Proximity sensorsProximity sensors represent a simple and inexpensive means of monitoring whether the motor is turning. By using a two-track proximity sensor, it is also possible to determine the direction in which the motor is rotating. Proximity sensors are mounted on the side of the fan guard, and thus do not add to the length of the motor.Signal outputs:Proximity sensors react to the attenuation lugs on the fan. The number of attenuation lugs deter-mines the number of pulses per revolution.01929AXXFig. 13: Setup of the proximity sensor systemThe proximity sensors are constructed with HTL technology and have an NO contact output which is actuated every time there is a pulse. This NO contact output switches the connected supply volt-age. Proximity sensors have a mark-to-space ratio of 1:1.01930AENFig. 14: Signal output of the proximity sensorsSignal level:The signal level is determined by the supply voltage, usually 24 V DC.

第五章 状态监测与故障诊断
第二节 利用PLC进行数控机床的故障检测
5.2.1 与PLC有关的故障的特点
1. 与PLC有关的故障首先确认PLC的运行状态，判断是自动运行 方式还是停止方式。
4. 硬件故障多于软件故障，例如当程序执行M07(冷却液开)，而 机床无此动作，大多是由外部信号不满足，或执行元件故障，而不 是CNC与PLC接口信号的故障。
第五章 状态监测与故障诊断
第二节 利用PLC进行数控机床的故障检测
5.2.2 与PLC有关故障检测的思路和方法
根据故障号诊断故障 根据动作顺序诊断故障 根据控制对象的工作原理诊断故障 根据PLC的I/O状态诊断 通过梯形图诊断故障 动态跟踪梯形图诊断故障
在调查故障现象，掌握第一手材料的基础上分析故障的起因，故障分析可采用归 纳法和演绎法。归纳法是从故障原因出发寻找其功能联系，调查原因对结果的影响， 即根据可能产生该故障的原因分析，看其最后是否与故障现象相符来确定故障点。演 绎法是从所发生的故障现象出发，对故障原因进行分割式的分析方法。即从故障现象 开始，根据故障机理，列出可能产生该故障的原因；然后对这些原因逐点进行分析， 排除不正确的原因，最后确定故障点。
第五章 状态监测与故障诊断
第一节 概述
5.1.1 故障的分类
根据机床部件、故障性质以及故障原因等对常见故障作如下分类： 1 按数控机床发生故障的部件分类 2 按数控机床发生的故障的性质分类 3 按报警发生后有无报警显示分类 4 按故障发生的原因分类
按故障发生时有无破坏性来分，可分为破坏性故障和非破坏性故障； 按故障发生的部位分，可分为数控装置故障，进给伺服系统故障，主轴 系统故障，刀架、刀库、工作台故障等。

2.二进制优先编码器
允许同时输入多数个编码信号，并只对其中 优先权最高的信号进行编码输出的电路。
一般编码器输入信 号之间是互相排斥的， 在任何时刻只允许一个 输入端请求编码，否则 输出发生混乱。
为何要使用 优先编码器？
优先编码器则允许多个输入信号同时要求编码。
注意： 输入：逻辑0(低电平）有效 输出：反码输出
.
13
电路扩展应用：
①输入信号的连接；
②级联问题（芯片工作的优先级）；
③输出信号的连接。
例：试用两片74LS148接成16线－4线优先编码器，将A0～ A15 16个输入信号编为二进制编码Z3Z2Z1Z0=0000～1111。 其中A15的优先权最高，A0的优先权最低。
