B–62073E–1/042. INTERFACE BETWEEN CNC AND PMC–NA OR NB
– 248 –
NOTE 1 0: Low signal 1: High signal
NOTE 2 The notations used in the table have the following meanings:
a/i : Absolute (1) or incremental (0)
Specifies whether an offset value is to be entered using an absolute variable or
incremental value.
g/w : Geometry (1) or wear (0)
Specifies whether a tool offset value is associated with geometry or wear.
r/l : Radius (1) or length (0)
Specifies whether the tool offset value (in milling systems) is a cutter compensation
value (radius) or tool length compensation value (length).
xzry : x (00), z (01), r (10), or y (11)
Specifies whether the tool offset value (in lathe systems) is an X–axis position
compensation value (x), Z–axis position compensation value (z), tool–tip radius
compensation value (r) or Y–axis position compensation value (y).
c/s : Clear (1) or set (0)
Specifies whether to perform message clearing or message setting.
t–type: – Tool number input
00 : Tool number specification using EID0 to EID31
01 : Specification of tool numbers to which compensation is currently applicable
(after an M06 command)
10 : Specification of selected tool numbers (before an M06 command)
– Tool number output
00 : Tool number output for tool data subject to input/output
01 : Output of tool numbers to which compensation is currently applicable (after an
M06 command)
10 : Output of selected tool numbers (before an M06 command)
emp : – Input
Always set this to 0
– Output
In the following cases, 1 is output:
1 Tool number output
⋅ When no tool number has been input since power–up
⋅ When there is no tool number to which compensation is currently applicable, or
there is no selected tool number
2 Pot number output and offset value output
When no pot number and offset value are set for tool data subject to output
NOTE 3 The ERDRQ column indicates the states specifiable for ERDRQ.
When 0 is indicated, only external data input is allowed.
When 1 is indicated, only external data output is allowed.
When 0/1 is indicated, both external data input and external data output are allowed.
NOTE 4 The dashed line (– – – –) in the EID/EOD column indicates an unused area. Be sure to set it
to 0 (low) for future expansion. This is output as 0.
NOTE 5 The EIHEAD/EOHEAD column specifies whether the data is for the first tool post or second
tool post. It also indicates whether the data is input data or output data. That is,
0/1: Data that is identified as applicable to the first tool post (0) or the second tool post (1)
x: Data that is identified as applicable to neither the first tool post nor the second tool post, and
is ignored
(This is always output as 0.)
