hello guys, i am also facing the same homing issue . 1)Step 1 -> i am giving motor the jog reverse command @ mode=7 and jog rev=1 . 2) Step 2 -> after machine reaches the homing sensor ,then mode =5 , and jog rev command is cut by the homing sensor input . also execute=1 . 3) Now after the step 2 sometimes the actual servo positon becomes zero and sometimes not . ------------------------------------------------------------------------------------------ |

Hello, The signal on binector input p2595 (start referencing) is used to trigger travel to the reference cam (p2607 = 1) if the reference point approach is selected at the same time via a 0 signal at binector input p2597 (referencing type selection). The signal in binector input p2595 (start referencing) must be set during the entire referencing process otherwise the process is aborted. Once started, the status signal r2684.11 (reference point set) is reset. The software limit switch monitoring is inactive during the complete reference point approach; only the maximum traversing range is checked. If necessary, monitoring of the software limit switches is reactivated after completion. The velocity override set is only effective during the search for the reference cam (see step 1). This ensures that the "cam end" and "zero mark" positions are always overrun at the same speed. If signal propagation delays arise during switching processes, this ensures that the offset caused during establishment of position is the same in each referencing process. Axes that only have one zero mark over their entire traversing and/or modulo range are identified using parameter p2607 = 0 (reference cam not present). Due to the missing reference cam, synchronization to the reference zero mark (step 2) is started for these axes after the referencing process is started. https://support.industry.siemens.com/cs/ww/en/view/109781535/128908526859 |
