Programming example
Example of macro definitions.
DEFINE M6 AS L6
DEFINE G81 AS DRILL(81)
DEFINE G33 AS M333 G333
Example of a global macro file:
After reading the macro file into the control, activate
the macros (see above). The macros can now be
used in the part program.

• Vocabulary words and reserved names must not
be redefined with macros.
• Use of macros can significantly alter the control's
programming language!
Therefore, exercise caution when using macros.
• Macros can also be declared in the NC program.
Only identifiers are permissible as macro names.
G function macros can only be defined in the
macro block globally for the entire control.
• With macros you can define any identifiers, G, M,
H functions and L program names.
• Macro identifiers with 1 letter and
1 digit are permissible (FM-NC only).

810D 840Di
On gear change, a subroutine is called to handle care of data
transfer. The actual tool change M function is output in the
subprogram (e.g. M106).
Emulation of the DIN G function
During thread cutting synchronization is requested with the PLC.
The original G function G33 was renamed to G333 by machine
data so that the programming is identical for the user.
