4-30Pr3.24 * Title Numerator of external scale division Relatedcontrol mode P S T FRange 0 to 220 Unit — Default 0Set up the numerator of the feedback scale dividing setup.When setup value = 0, encoder resolution is used as numerator of the division.Pr3.25 * Title Denominator of external scale division Relatedcontrol mode P S T FRange 1 to 220 Unit — Default 10000Caution• Check the number of encoder pluses per one motor revolution and the number of feedbackscale pulses per one motor revolution, and then set up the numerator of external scaledivision (Pr3.24) and the denominator of external scale division (Pr3.25) to establish theexpression shown below.• With Pr3.24 set at 0, the encoder resolution is automatically used as numerator.Example: When ball screw pitch is 10 mm, scale 0.1 _m/pulse, encoder resolution 20 bits(1048.576 pulses);Encoder resolution per one motor revolution [pulse]Feedback scale resolution per one motor revolution [pulse]=Pr3.24 1048576Pr3.25 100000If this ratio is wrong, the difference between the position calculated based on the encoderpulses and the position calculated based on the feedback scale pulses becomes large overa long travel distance and will activate the excess hybrid deviation error protection.Pr3.26 * Title Reversal of direction of external scale Relatedcontrol mode P S T FRange 0 to 1 Unit — Default 0NoteReverse the direction of feedback scale, feedback counter.Setup value Content0 Count value of external scale can be used as it is.1 Sign (positive/negative) of count value of external scale should be inverted.For setting method of this parameter, refer to P.3-12 Full closed control mode.Pr3.27 * Title External scale Z phase disconnectiondetection disableRelatedcontrol mode P S T FRange 0 to 1 Unit — Default 0Enable/disable Z-phase disconnection detection when A, B phase output type feedbackscale is used.Setup value Content0 Valid1 Invalid1.
