(0)  Dear expert, II have 802D powerline system,& want to introduce postioning to spindle ,the spindle motor is induction motor,we have introduce encoder to the system,(motor to spindle ratiois 1:10). 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

(0)  Hi You don't have to do anything to implement M19 because is a standard M function. 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

(0)      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....................                                                                                                                                                                                                                                             === Edited by Kutty19 @ 5/18/2012 7:34 PM [GMT ] ===

What you are refering the signals are of 828D check it... in 802D signal comes with VB series check it.... Regards, Prakash Please no technical questions by Private Message(PM), use the FORUM!!!!!
