HEIDENHAIN MANUALPLUS 620 User Manual page 178

Remember the following when converting DIN/ISO programs of the
CNC PILOT 4290:
Tool call (T commands of the TURRET section):
T commands containing a reference to the tool database are left
unchanged (example: T1 ID"342-300.1").
T commands containing tool data cannot be converted.
Variable programming: Variable accesses to tool data, machine
dimensions, D compensation values, parameter data and events
cannot be converted. These program sequences have to be
adapted.
M functions are left unchanged.
Names of external subprograms: When an external subprogram
is called, the converter prefixes "CONV_..." to the name.
If the DIN/ISO program contains nonconvertible elements,
the corresponding NC block is saved as a comment. The
word WARNING is inserted in front of this comment.
Depending on the situation, the nonconvertible command
is taken into the comment line, or the nonconvertible NC
block follows the comment.
HEIDENHAIN recommends adapting converted NC
programs to the circumstances of the MANUALplus 620
and then testing them before using them for production.
