First of all is it possible to introduce M19 positioning command in the spindle & how. As we have introduce incoder but when we give M19 command it gives contour monitoring alarm. Plz let me know how to do it. Thanks, Chetan

The only thing to do is to optimize the spindle positioning parameters (Kv, acceleration, and all the spindle parameters). You receive Contour monitoring alarm because with actual spindle parameters, the spindle is unable to reach the prescribed position either because of the parameters or some mechanical issues. First of all try to increase the contour monitoring parameter and see the window in which the spindle is positioned and after that try to optimize the parameters. Good luck Nit

Kutty19 Posts: 38 Rating: (1)	Dear, There is no PLC program required for this M19.... But only PLC required for enabling the encoder........ Then U goto setting data parameter 43240 enter some Position or Angel ( 0-359)..... Then U goto MDA run the Spindle in M3/M4 S100 for some time...... Then U give a command M70 M19 or M19 itself...... At this time spindle ll rotate in axes mode and it ll stopped at some angel.. That angel which we had given in that parameter........ While this time the CNC may gives Contour monitoring alarm...... U check the contour deviation value in service display..... Then U enter the max value in contour tolerence parameter........... Then it ll be over....................

Kutty19 Posts: 38 Rating: (1)	Ya Ur correct..... U use V2500 1002.3 single for Spindle on at the time of M19........... Thanks......
