We are in the final stages of reloading all the memory of our FV-45. When he calls an H code for tool offset, the display is off by 5 inches. If we call the G55 with no tool, it correctly displays the work offset position. The parameters and macros were re-loaded from a very old tape.

We are getting by for now by manually adjusting by 5 inches, but I can't find a parameter or setting to change this.

Anyone have an idea?

check manual/absolute.

Thanks for the reply. We looked at it and don't see anything.

It seems to only be when we call the tool offset.

Confirm the value in parameter 2202 bit 2 (3rd bit from right)

DTL

0 : The incremental and absolute positions displayed on the CRT include the distance traveled by tool length compensation/tool length compensation in tool axis direction.

1 : The incremental and absolute positions displayed on the CRT do not include the distance traveled by tool length compensation/tool length compensation in tool axis direction. Namely, the positions specified by the program are displayed.

2202 is all zeroes. I noticed that our FH-55 with the same control has that bit as a 1.

UPDATE: That was it.

Thank you.
