Measuring units per revolution Number of Revolutions Denominator If it is not possible to enter parameter data in the permitted ranges of numerator and denominator the attempt must be made to reduce these accordingly If this is not possible it may only be possible to represent the decimal number affected approximately The resulting minor inaccuracy accumulates for real round axis applications infinite applications with motion in one direction A solution is e g to perform adjustment after each revolution or to adapt the mechanics or gearbox accordingly The parameter Measuring units per revolution may also be decimal number however the Total Number of Steps may not The result of the above formula must be rounded up or down The resulting error is distributed over the total number of revolutions programmed and is therefore negligible Preferably for linear axes forward and backward motions The parameter Revolutions Denominator can be programmed as a fixed value of 1 The parameter Revolutions Numerator is programmed slightly higher than the required number of revolutions This ensures that the measuring system does not generate a jump in the actual value zero transition if the distance travelled is exceeded To simplify matters the complete revolution range of the measuring system can also be programmed The following example serves to illustrate the approach Given Measuring system with 4096 steps rev and
