SOCAPEL SA SOFTWARE FOR SYNCHRONIZATION OF AXES 024.8068.A8.12.5 Parameter ZMPOTThis parameter expresses a dead band around <strong>the</strong> reference value; a voltage inside<strong>the</strong> limits is considered as null.The value <strong>of</strong> ZMPOT must be positive, between 0 and 32,767 (hexa : 1 ... 7FFF).Address :191 (hexa : BF)Default value : 0.8.13. MISCELLANEOUS PARAMETERS8.13.1 Parameter TIMTOPThis parameter can be employed to improve <strong>the</strong> precision <strong>of</strong> instructions ETOP andINIPM whenever <strong>the</strong>y are available. What TIMTOP actually expresses is <strong>the</strong> physicaldetection and transmission delay that triggers <strong>the</strong>se functions. One lsb in TIMTOPequals 0.02844 ms. The s<strong>of</strong>tware takes account <strong>of</strong> this delay and <strong>the</strong> speed to correct<strong>the</strong> corresponding positions.Computation <strong>of</strong> parameter TIMTOP takes account <strong>for</strong> <strong>the</strong> reaction time <strong>of</strong> <strong>the</strong> sensorand <strong>the</strong> 96delay dued to <strong>the</strong> input filter. A 1/6 ms delay must be added, whichcorresponds to half <strong>of</strong> <strong>the</strong> capture-time uncertainly (ST1 s<strong>of</strong>tware cycle-time is1/3 ms).If input INO <strong>of</strong> <strong>the</strong> LIO board is used, this uncertainly may be reduced to 0.01422 ms.TIMTOP value must be <strong>the</strong>n incremented by 32,768.Example 1 : Sensor delay : 2.5 msInput filter delay :0.6 msCapture-delay (average) :0.167 msTotal average delay :3.26 msTIMTOP = 3.26 ms / 0.02844 ms = 115Example 2, using input INO :Sensor delay :Input filter delay :Capture-delay (average)Total average delay :TIMTOP = 1.814 ms / 0.02844 ms + 32,768= 32,832 (hexa : 8040)1.2 ms0.6 ms0.014 ms1.814 msAddress :56 (hexa s : 9C)Default value : 0.87
