I have a 1990 interact 308 with a TNC 2500. The machine lost the parameters and I am haveing some problems getting the machint act correctly. I do have a prameter list but not all the parameters are listed. For Example in my list MP1350's value is 15 but the machine is showing 1350.0,1350.1,1350.2.... After some research on this site i determined that the encoders are all rotary type and set the values to 2.
Here is the problem....
During the "pass over ref" test the Z axis acts as expected and the X axis acts as expected. The Y axis moves to the limit switch like it should. Then it backs up to the ref mark in the encoder (I assume). The other two axis are referenced at this point and this should be the end of the positioning but the y axis after backing up moves y+ untill it hits the end of the screw and starts to load up the motor. The limit switch has two ramps and two switches on it. When the motor moves to the end of the screw, THe second ramp/switch seems to have no effect on the process. I have gone back thru the prameters but dont find any discrepancies. Does anyone have any sugesstions?
