Based on this, inductive sensors and integrated evaluation electronics (ASIC) have been developed to create a new and powerful generation of measuring systems. </p><p>The AMOSIN length measuring systems are supplied as open, nonguided systems or as guided encapsulated systesms. AMOSIN systems are very well able to resist environmental influences such as dust, humidity and so forth, and also feature extremely high resistance to shock and vibration. The high precision is mainly due to the procedure used to manufacture the rigid steel measuring scale, and to the exceptionally high quality sensor signal, with deviations in the sine wave down to &lt; 0.1 % harmonic content, as a measure of the achievable interpolation precision within the gra-ting pitch. As will be seen from the measuring principle described below, the measuring system does not include any magnetic parts (either in the scale or in the scanning head). As a result it is not at all sensitive to electromagnetic interference of any kind and has no hysteresis in contrast to magnetic measuring systems. The systems output interfaces either 1 Vpp sine/cosine signals, or RS-422 square wave signals, in real-time. </p><p>The wide range of available AMOSIN length measuring system types covers a wide area of applications from high accuracy positioning for mea-suring machines and pick and place machines over machine tool, sheet metal working machines to direct drives where high dynamic range and stiffness is required.</p><p>General properties</p><p>Not sensitive to soiling - IP67 </p><p>Not sensitive to interfering magnetic fields </p><p>High precision </p><p>High resolution </p><p>Speed up to 30 m/s </p><p>Operation temperature -10C to 100C </p><p>Analog output 1Vpp with divided signal period till 10m </p><p>Digital output RS-422 / TTL with resolution till 0,125m </p><p>Any measuring length </p><p>Integrated reference pulse, also distance coded </p><p>Typical applications</p><p>Machine tool </p><p>Direct drives </p><p>Sheet metal working machines </p><p>SMT- pick and place machines</p><p>Measuring machines </p><p>Medical equipment </p><p>Printing machines </p><p>Punching machines </p><p>Hydraulic axes </p><p>Electronic production equipment </p><p>AMOSIN - General information</p><p>ELECTROMATEToll Free Phone (877) SERVO98</p><p>Toll Free Fax (877) SERV099www.electromate.com</p><p>sales@electromate.com</p><p>Sold &amp; Serviced By:</p></li><li><p>5Allgemeine InformationenGeneral informations</p><p>AMOSIN - LngenmesssystemeAMOSIN length measuring systems</p><p>AMOSIN - Measuring principleThe AMOSIN measuring systems function on the principle of a transformer with a moving reluctance core. The mutual inductance of the primary and secondary windings of a transformer changes in accordance with the relative position of the core. The AMOSIN system consists primarily of a planar coil and a measuring scale (Fig.1). The coil structure, with a number of wind-ing elements (individual main elements with primary and second-ary SIN/COS coils) aligned in the direction of measurement, is implemented on a substrate using micro-multi-layer technology. The measuring scale is a stainless-steel tape onto which a highly precise graduation (e.g. = 1000 m) of variable reluctance has been etched using photo-lithographic techniques.The relative movement in the direction of measurement between the sensor structure (in the scanning head) and the measuring scale periodically changes the mutual inductance of the individual coils, generating two sinusoidal signals with a 90 phase shift (SIN and COS). The extremely accurate signal, and its immunity to environmental influences has the effect that after conditioning of the signal in the evaluation electronics (Fig. 2) deviations of no more than 0.1% from the ideal sinusoidal form (harmonic content) remains. This allows high interpolation factors (further levels of sub-dividing ) to be carried out in the course of signal digitisation. This can either be done in the measuring system itself, or in the subsequent electronics (CNC etc.).</p><p>An important feature of the principle of operation is that using the AMOSIN technology does not give rise to any measurement hysteresis (ma-chine backlash error). In contrast to magnetic systems, the high-frequency alternating field suppresses any hysteresis in the material.</p><p>The evaluation electronics conditions the sensor signals and interpolates them continuously, without strobe times, exploiting a novel circuit prin-ciple. It then supplies the measurement information at the output through differential interfaces and linedrivers, either as a sinusoidal signal or as a square wave signal. (See the signal diagram on Page 47) </p><p>In addition to the periodic quadrature signals (A, B and their inverted) a reference signal is output for the determination of absolute position. This signal is generated from individual marks integrated into the measuring scale, and does not require any additional parts.

Precision within one grating pitch - primarily determined by the quality of the sensor signal and the evaluation electronics of the scanning 2. head. </p><p>The following should also be considered for the measuring systems with a 1 Vpp output interface: </p><p>Precision of the analog/digital conversion at the input stage of the subsequent electronics (in the controller) 3. Noise coupled into the output signals as it is transferred from the scanning head to the subsequent electronics 4. </p><p>A detailed description of these aspects follows:</p><p>1. Scale accuracy</p><p>Every measuring scale is measured on a linear test bench and a test certificate quoting the precision class in accordance with the specification, is completed. Optionally a measuring diagram (registered under ideal assembly conditions) can be supplied as follows.</p><p>2. Precision within the grating pitch</p><p>The periodical deviation which appears within the grating pitch is less than 0,1% of the pitch because of the high quality of the sensor signal and the signal evaluation (e.g.. maximum deviation is 0,5m on a 500m grating pitch).This high accuracy level will be achieved not just for the ideal, nominal mounting and environmental conditions but for the whole specified func-tional range of geometrical mounting deviations and temperature.</p><p>In order to suppress the errors discussed above under points 3 and 4, a new output interface has been implemented in the new generation of AMOSIN systems, in which the sine, cosine and reference signals, for the 1 Vpp output interface can be divided and delivered over line drivers (see signal diagram on Page 47). The divided output signals (with programmable dividing factor) are generated in real time with signal periods down to 10 m.</p><p>The effect of any possible deviation in the evaluation of the encoder signals in the subsequent electronics (controller etc.), is reduced exactly by the dividing factor that is applied. In addition, this reduced sinusoidal signal period leads to finer quantisation in the subsequent electronics, which is of particularly great importance to demanding high stability, high stiffness drive applications. Additionally, the signal dividing reduces the effect of interfered noise on the signal transfer line in proportion to the dividing factor; in other words, an improved signal/noise ratio is achieved.</p><p>The metrological principle on which the AMOSIN systems operate means that they are entirely free from hysteresis and dont lead to a backlash effect.</p><p>-20</p><p>-15</p><p>-10</p><p>-5</p><p>0</p><p>5</p><p>10</p><p>15</p><p>20</p><p>0 200 400 600 800 1000 1200 1400 1600 1800 2000 2200 2400</p><p>Messlnge [mm]Measuring length [mm]</p><p>Abw</p><p>eich</p><p>ung </p><p>[m</p><p>]Er</p><p>ror [</p><p>m]</p><p>ELECTROMATEToll Free Phone (877) SERVO98</p><p>Toll Free Fax (877) SERV099www.electromate.com</p><p>sales@electromate.com</p><p>Sold &amp; Serviced By:</p></li><li><p>7Allgemeine InformationenGeneral informations</p><p>AMOSIN - LngenmesssystemeAMOSIN length measuring systems</p><p>ELECTROMATEToll Free Phone (877) SERVO98</p><p>Toll Free Fax (877) SERV099www.electromate.com</p><p>sales@electromate.com</p><p>Sold &amp; Serviced By:</p></li><li><p>8AMOSIN - LngenmesssystemeAMOSIN length measuring systems</p><p>Allgemeine InformationenGeneral informations</p><p>Selection Table</p><p>Grating pitch500 m 1000 m 3000 m</p><p>Non</p><p>-gui</p><p>ded </p><p>syst</p><p>ems</p><p>Ma</p><p>band</p><p>typ</p><p>Scale with adhesive Scale mounted on carrier</p><p>LMB-1x50LMB-4x50</p><p>Page 9</p><p>LMB-1x0LMB-4x0</p><p>Page 9</p><p>LMB-130LMB-430</p><p>Page 9</p><p>Abt</p><p>astk</p><p>opfty</p><p>p</p><p>Miniature scanning head with external electronics</p><p>LMK-105x</p><p>Page 21</p><p>LMK-10x</p><p>Page 21-</p><p>Scanning head with integrated electronics</p><p>LMK-115xLMKF-115x</p><p>Page 27</p><p>LMK-11xLMKF-11x</p><p>Page 27</p><p>LMK-13xLMKF-13x</p><p>Page 27</p><p>Standard flat</p><p>Gui</p><p>ded </p><p>syst</p><p>ems Sc</p><p>ale </p><p>type</p><p>Measuring rail</p><p>LMF-3150LMF-3250</p><p>Page 37</p><p>LMF-310LMF-320</p><p>Page 37</p><p>-</p><p>Scan</p><p>ning</p><p> hea</p><p>d ty</p><p>pe</p><p>Measuring slider</p><p>LMK-315x</p><p>Page 43</p><p>LMK-31x</p><p>Page 43-</p><p>High resolutionHigh accuracy</p><p>High mounting tolerancesHigh dynamic</p><p>LMKF-110LMK-110</p><p>LMK-100</p><p>LMB-100 LMB-400</p><p>ELECTROMATEToll Free Phone (877) SERVO98</p><p>Toll Free Fax (877) SERV099www.electromate.com</p><p>sales@electromate.com</p><p>Sold &amp; Serviced By:</p></li><li><p>9Measuring scales for non guided AMOSIN measuring systems</p><p>Measuring scale for adhe- sive mounting or stainless steel extrusion as a carrierEasy to mount Can be combined with all non guided AMOSIN scan-ning heads</p><p>ELECTROMATEToll Free Phone (877) SERVO98</p><p>Toll Free Fax (877) SERV099www.electromate.com</p><p>sales@electromate.com</p><p>Sold &amp; Serviced By:</p></li><li><p>10</p><p>Offene AMOSIN - LngenmesssystemeOpen AMOSIN length measuring systems</p><p>MaverkrperungScale types</p><p>LMB-100 - Measuring scale for open measuring systems, mounted with adhesive</p><p>Technical data</p><p>Configuration</p><p>LMB-1050 / 1150 LMB-100 / 110 LMB-130</p><p>Grating pitch:500 m 1000 m 3000 m</p><p>Accuracy after linear compensation:bis zu (down to) 3 m/m bis zu (down to) 5 m/m</p><p>Coefficient of expansion:~ 11 ppm/K</p><p>Measuring length:Any lengths up to 30m</p><p>Mechanical execution:Stainless steel measuring tape with adhesive layer for mounting</p><p>Reference marks:1 reference mark as standard or any desired number and position or distance coded </p><p>(see page 48)</p><p>At the open, non-guided systems a double sided adhesive foil is applied on the measuring scale for direct sticking on the machine bed.
