Need Help!- Hitachi Seiki HT-20 Threading problem

[wiks]

Hello everyone, i'm having a problem with getting the threading going on my machine. It's using the Yasnac LX2 controls. For some reason it stops on the G92 line of the program, no alarm, the spindle keeps spinng but the turret is not moving. I checked the position page and it came down on the X position in the G92 line but it stops there. I have also tried G76 and G32 cycles and they all do the same thing. I replaced the encoder but it didn't help. Here's an example of the program i put in, maybe i'm missing something...

N3 T500
G97 S800 M03
G0 Z.5 T505 M08
X1.1
G92 X1. Z-1. F.05
X.990
X.980
X.970
and so on...

The machine will run the cycle in dry run mode. I checked the parameters and compared to the book, but again they are not crystal clear. The machine has the threading option because the previous owner used it.

Does anyone maybe have a list of what the parameters should be or have any ideas on what it could be? Ohhh... i just recently acquired the machine and the parameters were corrupt when we fired it up, we had a company come out and put them in and have asked them for assistance but they are running out of ideas themselves.

Thanks,
Z

Maximum feedrate at G98 command (feed per minute)

place F with E, and leave it feed per rev.

Hey Newtexas,

I tried it and it still did the same thing. For some reason it just sits there on the G92 line, it came down on X and screen is blinking "f" for feeding but it isn't moving. I found a guy with the same machine and control and he was kind enough to send me his parameters. There was quite a few that was different, i changed them and it helped with other problems i was having but the threading still is doing the same thing. I'm wondering if this is a hardware or still a parameter problem????? Thanks for the help, very appreciated.

Would anyone maybe know how to get to the option parameters? I cant find them, i have found the control and macro parameters.
