2 Sequence number
[Input] A sequence number can be specified to search for the block to be
executed in memory command mode. A sequence number within the
range of 1 to 99999999 can be specified, using binary codes.
NOTE
A search can be performed only when the following
conditions are satisfied:
1 MEM mode is selected.
2 Automatic operation is reset. (Automatic operating
signal OP is 0.)
3 The system is not being reset. (Resetting signal RST
is 0.)
[Output] The sequence number of the block currently being executed can be
output.
3 Tool offset value
[Input] An offset number can be specified to change the tool offset value. The
following specifications are possible, using part of an address:
1. For milling systems, whether cutter compensation amount or tool
length compensation amount.
For lathe systems, whether X-axis position compensation amount,
Z-axis position compensation amount, tool-nose radius
compensation amount, or Y-axis position compensation amount.
2. Whether geometric or wear.
3. Whether an absolute value or incremental value. If an absolute
value, the value specified in the data section is directly used as the
new tool offset value. If an incremental value, the value equal to
the current offset value plus the specified value is assumed to be
the new tool offset value.
An offset number can be specified using binary codes between 0 and
999. If a number other than those provided by the compensation
amount memory (which depend on the option used) is specified, an
alarm is issued. If 0 is specified as an offset number, the tool offset
number currently selected for execution is selected. A compensation
amount can be specified with binary codes within the range of 0 to
+999999999, with the least input increment used as the units.
[Output] An offset number can be specified to output the current tool offset
value.
Upon an output request, an offset number must be specified. The
specification is the same as that at input. The output data includes the
corresponding offset number. If offset number 0 is specified, not 0 but
the offset number currently selected for execution is output. In the
address section, the specification of whether the value is absolute or
incremental has no meaning.
