  • Page 5 select The LIK series of incremental encoders from NUMERIK JENA are equipped with features which are supposed to fulfill these high requirements in an ideal way. • Due to an interpolation up to 64-times a resolution down to 78,125 nm is possible without any additional electronics. • The permissible traversing speed for a sinusoidal signal output amounts to 10 m/s. A square wave signal output with a resolution of 0.1 μm allows a permissible traversing speed of 1.6 m/s. • The short-range position errors (interpolation errors) were significantly reduced by introducing an electronic compensation of amplitude and offset deviations of the coarse signals. This compensation functions without following error in all velocity ranges. Applications: • Production and inspection machines for the semiconductor industry • Linear units, drives and coordinate tables • Measuring machines and measuring microscopes • Positioning and measuring devices for medical technology • Precision devices for reprography • Precision machining • Robotics Additional features: • Wide range of integration and configuration options through modular system • Compact size and ultra flat design • Customizable sensor frames and housings available • Reference signal(s) with repeatability accurate to a specific increment, regardless of the direction from which the reference mark(s) is/are traversed •...

  • Page 13: Reliability

    select Reliability With its compact dimensions, the exposed linear encoder from NUMERIK JENA is equipped with two scanning fields. The scanning signals are generated by two large 1.1 mm² sensor fields. Local contamination on the measuring element such as dust, fingerprints or particles have only a minor effect on the signal amplitude, as the ASIC SV4 installed in the measuring head monitors the signals and eliminates any deviations in the amplitude. If the signal amplitude decreases due to the presence of contamination on the measuring scale, the sensor amplifier readjusts by increasing the signal amplification. The output signals do not change in offset and phase position. The result is a constant signal shape. This measuring system is especially suitable for applications that require high reliability.

In order to avoid counting errors, the interpolator‘s output frequency is matched to the counting frequency of the operator‘s evaluation electronics. This adaptation is possible in discrete frequency steps. For the selection of the appropriate interpolation factor or speed factor, see the chart in chapter 11.

  • Page 29: Sensor Without Frame

    select 6.3.3 Sensor without frame For measuring systems supplied without a frame, the customer must attach the measuring system to the frame. This pressure-, shock- and contact-sensitive area must not be selected for alignment or fixing of the sensor mo- dule during the installation process. Mechanical stress can lead to the destruction of the sensor. Step 1: Secure the aligned sensor in the frame. To do this, apply some spots of adhesive to the centre of the fix point. If the corners of the sensor are fixed in the frame with a glue dot, please check the exact alignment and planarity. Step 2: The adhesive can be applied all around, but at least 5 m m long adhesive beads should be applied to the long sides of the sensor. To ensure that the high-precision measuring system works properly, no adhesive residue should remain on the sensor surface. Image 24 Note the usage requirements of the manufacturer! Recommended adhesives: Cyanoacrylate-based adhesives such as LOCTITE 480 or LOCTITE 401, as well as 2-component epoxy adhesives such as DELO AD 840.

  • Page 32 select Step 2 • Use a solvent to clean the adhesion surface of the machine (e.g. Acetone or Alcohol). • Make sure that no contaminations remain on the machine‘s adhesion surface. • Dirt or other elements between the machine and scale tape cause local differences in the spacing between the scale tape and the scanning head. This may diminish the encoder‘s functionality and/or result in measuring errors. • The scale tape can be mounted in a slot already on the machine or along an edge already on the machine. • Place the edge of the scale tape exactly on the marking for the beginning of the scale tape. • Run the scale tape exactly along the slot or edge when applying it.

  • Page 36 select Step 8 • Ideally, the sensor mounting is constructed by the customer in a way that the mounting height of the sensor can be adjusted. • Place the measuring head on the mounting device and tighten both fastening screws alternately lightly and evenly (tightening torque = 0.5 Nm). • To check the parallelism between the housing of the measuring head and the scale tape, you can use the spacing gage “1.4”. This serves only as a guideline for an approximate check of the mounting, since the ideal working distance of 1.4 mm refers to the distance between the sensor glass and the measuring standard. • If available – slide the spacing gage “1.4” lengthwise between the scale tape surface and the scanning head and check for even play. • Please take care not to scratch the measuring system when removing the spacing gage. If it is difficult to remove or jammed, loosen the scanning head and repeat the installation procedure. Otherwise the surface of the sensor module can be damaged! Image 32 36 / 52...
  • Page 37 select Step 9 • Mount the PCB (tightening torque = 0.1 Nm) and provide strain relief near the scanning head. • Connect the encoder cable to the evaluation electronics and pay attention to the pin assignment. The evaluation electronics must be switched off! • After connecting the encoder cable, switch on the evaluation electronics and and perform a function test. • If there are errors in the function or during measurement, please read chapter 10 “Troubleshooting” first.

  • Page 48: Speed Chart For Likselect Series

    11.2 Speed Chart for LIKselect Series The maximum attainable traversing speed of the encoder is determined by the maximum output frequency of the interpolator and/or the minimum counting frequency of the operator‘s evaluation electronics (e.g. controller or display). Please take the suitable values for your application from the following chart and select it in the ordering key. First select the interpolation factor you have chosen and the traversing speed you are aiming for. Once you have found the corresponding specifications, please check whether your evaluation electronics guarantee the correspondingly necessary counting frequency. The listed values in the chart refer to a grating period (TP) of 20 µm.
