I am trying to program a Nomura nn13 lathe we purchased. This program will use the sub spindle to pick the part off. The problem I have is that the sub spindle hits a soft limit about 35mm before the end of its travel when jogging toward the guide bush. The machine manual says it should have -4mm and +170mm of travel on Z2 axis, and we are only getting -1mm and +135mm. The part I am making is 26mm long so I am unable to pick it off for back work. This leads me to believe that the previous owner may have changed the soft limits. When I go into the user parameters under soft limits I do not see any parameters relating to Z2, I only see X1, Y1 and Z1. I tried going into the M mode under plc/if screen, and still do not see any parameters for Z2. I think I need to find the $2 parameter area but have not been able to locate it. If anyone knows how to access these parameters, that would be of great help.

thanks
Eric
