I have a Mori Seiki SL 7 lathe with Fanuc 6T - B control. Referece for both axis is not working in zero return mode in selector swich by jogging using jog switch. Both axis are moving to end limit without catching reference point. But, in MDI mode, using code, zreo return is working ok for both axis. Can somebody help me to solve this problem? The machine was down for about one year because of spindle problem and now it is solved. During down time, the machine was made on every day and manual dry movements were done. All the parameter values remain same as original. Battery backup is ok. Now, the machine is working ok in auto mode after referencing in MDI mode. I want some help to solve referencing in zero return mode.Thanks.
