FANUC 18iT, tool measuring

[MRPM]

Our lathe has this tool measuring device and when measured with it the tool offset values X and Z get incorrect values. This can be fixed, i believe, by changing the values of the following machine parameters:

PARAMETER (TOOL OFFSET)

5015 MEASURE (XP) -838580
5016 MEASURE (XM) -759014
5017 MEASURE (ZP) -2744462
5018 MEASURE (ZM) -2704891

Am I right?

And another thing: To make changes in the machine parameters the parameters must first be unlocked. I've done this before but how again did it go? (Just trying to save work time here...)

Yes, you're correct with the parameter numbers.

To edit the parameters, proceed as follows:

1. Place the NC in the MDI mode.
2. To display the setting screen, press the SETTING function key as many times as required, or alternatively press the SETTING function key once, then the SETTING section select soft key. The first page of the setting screen appears.
3. Position the cursor on “PARAMETER WRITE” using the cursor move keys.
4. Press the [(OPRT)] soft key to display operation select soft keys.
[NO.SRH] [ ON:1 ] [ OFF:0 ] [+INPUT] [INPUT]
5. To set “PARAMETER WRITE=” to 1, press the ON:1 soft key, or alternatively enter 1 and press the INPUT soft key. At this time an alarm condition (P/S100 PARAMETER WRITE ENABLE) will occurs; this is normal. The parameters can now be set.
6. Once trough setting the parameters, set “PARAMETER WRITE” back to 0 and press Reset to clear the P/S100 alarm.
