SOCAPEL SA SOFTWARE FOR SYNCHRONIZATION OF AXES 024.8068.A8.5.4 Parameter FILTEIThe OEI board contains a digital filter, <strong>for</strong> use when <strong>the</strong> encoder environment containsa high degree <strong>of</strong> disturbance. The parameter FILTEI gives <strong>the</strong> maximum frequencygenerated by <strong>the</strong> encoder : <strong>the</strong> filter removes frequencies above this value. Thefollowing table gives <strong>the</strong> value <strong>of</strong> FILTEI as a function <strong>of</strong> <strong>the</strong> maximum speed <strong>of</strong> <strong>the</strong>application :FILTEI 0 1 2 3 4 5 6Dashes/s 250,000 100,000 27,500 3,500 875 190 0Address :102 (hexa 66)Default value : 0.8.5.5 Parameter ACCLIMIn an OEI system, if <strong>the</strong> encoder resolution is coarse, <strong>the</strong> obtained reference willcontain noise, especially if <strong>the</strong> slave is rotating much faster than <strong>the</strong> master.It is possible to reduce this noise by limiting <strong>the</strong> resulting acceleration using <strong>the</strong>parameter ACCLIM.Caution : ACCLIM must not limit <strong>the</strong> real acceleration measurement on <strong>the</strong> mastershaft : this would have <strong>the</strong> effect <strong>of</strong> cutting an electric shaft drive.ACCLIM is calculated by reference to values CA1 and CA2, using <strong>the</strong> following<strong>for</strong>mula :ACCLIM=CA1( ouCA2)⋅ CKA2⋅CRANSThe value <strong>of</strong> ACCLIM must always be positive, between 0 and 32,767(hexa : 0 ...7FFF).Address :174 (hexa : AE)Default value : 32,767 (hexa : 7FFF).64
