Axis Letter

In 5X machines, each rotary axis has a corresponding letter (just like the X, Y and Z linear axes). It is possible to specify that letter in GPP2, by setting the following variables: M5_A_LETTER for the alpha axis, M5_B_LETTER for the beta axis.

Using the letter variables inside the EX2 program makes the post-processor more generic. For instance, consider the following typical lines:

  IF_SET (A_CURPOS)  OUTPUT " " M5_A_LETTER A_CURPOS;   END_IF;

  IF_SET (B_CURPOS)  OUTPUT " " M5_B_LETTER B_CURPOS;   END_IF;

These lines work for any machine, regardless of the specific axis names (A, B or C).

The same letters are also used in the output for the machine simulator - see later section in this manual.

These variables may contain more than one letter. For example, "C1" or "C2" may be used instead of just "C" - depending on the machine requirements.
