I have set up many NEW TOOL EDGES in the tool list on my CNC lathe using the Siemens 808D Advanced Control BUT when I use the same method to make a new tool edge on my milling machine using the same Siemens 808D Advanced Controls I end up getting this alarm #17184.

I have a column in the mills tool list of "H" I do not know what this is or what it is for

Is this what is causing the alarm code?
