2. Commissioning General information NOTICE Interference from sources of high electromagnetic emission! Peripheral devices, such as frequency inverters or servo drives, may couse interference. • To increase the noise immunity to electromagnetic influences, use the optional functional ground connection as per IEC/EN 60204-1 NOTICE Engaging and disengaging connecting elements! Risk of damage to internal components.
Page 12 (http://www.amo-gmbh.com/en/downloads/accessory/) Choice between 32 and 64 bit version: Download and install the file "AMO-Check Installer.exe". 2.3 Connect Encoder and STU-60 diagnostic tool to the PC DANGER Risk of electric shock! Improper grounding of electrical devices may result in serious personal injury or death.
Page 13  In „Open Loop“ the encoder is supplied by the STU-60 and the output signals of the encoder are not transfered to the controller. So in this case the axis has to be controlled by a motor encoder or moved manually.
Page 14: Closed Loop
Only the adapter cable provided by AMO should be used. Step 3: Connect the USB port of the STU-60 and the USB port of your PC with the included USB cable. Only the USB cable provided by AMO should be used.

Step 3: Connect the USB port of the STU-60 and the USB port of your PC with the included USB cable. Only the USB cable provided by AMO should be used. The encoder signals and mounting condition can now be checked with the STU-0.
Page 16 2.4 Start the AMO-Check software Double-click to open the "AMO-Check" application: The AMO-Check start window opens (top left the current revision level is shown).
Page 17 All important system information can be read out in the "Diagnose" window. Mounting conditions and the internal Signals can be checked in real time. 4. Function Record/Replay If you want to forward your measurements to the AMO service department, use this function and send the records via email to: service@amo.at...
Page 18 "SIN / COS" window to the "RI" window. The playback only works with this function of the AMO-Check software. The STU-60 does not need to be connected to play the recorded data.

5. Single Head Solution Selection menus Various functions can be selected using the menu bar. 5.1 Device Type All known encoder information are listed (name, serial number, interface, etc.).
Page 20: Amplitude Sin/Amplitude Cos
5.2 Signal Adjustment In this function, the signals read from the encoder are compared with the ideal values set by AMO. Thus, you can determine the optimal mounting and reposition the encoder if necessary. Amplitude Sin/Amplitude Cos Here you can determine the deviation from ideal air gap.
Page 21: Reset Min/Max
Reset Min/Max The black bars left and right (minimum and maximum reached value) can be reset by this function.  Press reset Min/Max Now the lowest and highest measuring values have been reset to the current measuring value. 5.3 Incremental Signal Display The input signals can be checked by using a virtual oscilloscope.
Page 22 Circular representation In the circular representation the allowed amplitu- de range is marked green. The current signal am- plitude is displayed in black. When moving the encoder, a circle is created, every recorded ampli- tude value disappears after a time of 1.5 seconds. Time representation To perform this test, select the "SIN / COS"...

Page 24 6. Multi Head Solution - MHS Various functions can be selected using the menu bar. 6.1 Device Type All known encoder information are listed (name, serial number, interface, etc.).
Page 25 6.2 MHS-System In this window, the eccentricity of the scale tape can be checked. Current Mode MHS without Offset-Function: As soon as the MHS is powered on, it is in single-head mode. Here, the MHS works with single-head scan- ning → when crossing the first reference mark, it switches to dual-head mode (double-head operation). From this point on, the eccentricity of the measuring scale is corrected.
Page 26 Offset-Funktion Example below: In this version of the encoder, the offset function is not supported. If the offset function is present, the following window is available:...
Page 27 Now by pressing the button "Save Offset" the offset value can be stored in the MHS . The upper status dis- play should now turn yellow. If an offset is already stored and one or both measuring heads are dismounted, a new setting of the offset is required.
Page 28 Corrected Error by MHS - Full Flange Turn The eccentricity of the scale tape can be displayed in this diagram, by moving the axis. On the Y-axis the deviation is given in μm. The existing deviation is corrected by the MHS and therefore has no effect on the system accuracy.
Page 29 6.3 Head # 1/2 - Signal Adjustment In this function, the signals read from the encoder are compared with the ideal values set by AMO. Thus, you can determine the optimal mounting and reposition the encoder if necessary. Amplitude Sin/Amplitude Cos Here you can determine the deviation from ideal air gap.
