The control has two offset tables: geometry and wear table. The sum from
these two tables is used to generate tool length data when the tool offset
number is programmed. When in 7300 mode, the active offset is also
computed as the sum of the geometry and wear offsets. Refer to chapter 3
for details.
When changing from inch to metric (or vice versa) in 7300 mode, the
control does automatic conversion on tool offset values. The 7300 did
not provide this automatic conversion and, instead, required the operator to
re-enter tool offsets.
A T-word cannot be programmed in circular interpolation mode (G02 or
G03).
Important: The control allows the Power-Turn-On (PTO) mode of the
control to be specified in AMP with respect to inch/metric (G70/G71) and
absolute/incremental (G90/G91) etc. For 7300 tape compatibility, these
parameters may need to be modified if a certain PTO mode is expected.
Refer to the AMP manual for details.
In this section, we describe how to copy a 7300 tape to the control. This
process involves these steps:
store a 7300 part program and pattern repeat into the control
execute the 7300 part program and patten repeat
Storing 7300 Part Programs
A 7300 tape can be stored in control memory by using the COPY
PRGRAM softkey function. While reading the tape to the control, any TN
code, which defined the program name for 7300s, is interpreted as a
comment block; this means a new program name must be entered. The
control prompts you to enter a program name for each part program or
pattern repeat stored. The name given to the program must adhere to the
format of control program names.
Important: When storing a pattern, the pattern name entered here must be
a 1-to 5-digit numeric prefixed with the letter O; for example, O10005.
Refer to section 11.5.9 for information on valid subprogram names.
At this time, the control creates an internal cross-reference table for all
pattern repeat names. The cross-reference table is generated so that any
blocks that call pattern repeat do not need to be rewritten with the new
program name. Refer to the section on Pattern Repeat for details.
You can not copy pattern repeat programs from memory to memory.
Doing so does not create the necessary cross-reference table.
