Pee Ell Sea Posts: 672 Rating: (57)	Hi, Encoder can be a problem if you are not getting the reference pulse. Can you perform spindle positioning. i.e. SPOS = 0 Pee

Ekalavya Posts: 2964 Rating: (484)	Hello.... It is not like that....when your doing the threading operation....it looks for the position if this not proper you have this error....try to command the spindle RPM in MDA and check the exact RPM what you have commanded is displayed on the screen.... Check it .... Regards, Prakash
