Word structure and address
Functionality/structure
A word is a block element and mainly constitutes a control command. The word consists of the following two parts:
●
Address characters
: generally a letter
●
Numerical value
: a sequence of digits which with certain addresses can be added by a sign put in front of the address,
and a decimal point.
A positive sign (+) can be omitted.
The following picture shows an example of the word structure.
Several address characters
A word can also contain several address letters. In this case, however, the numerical value must be assigned via the
intermediate character "
=
".
Example:
CR=5.23
Additionally, it is also possible to call G functions using a symbolic name (For more information, refer to Section "List of
instructions (Page 258)".).
Example:
SCALE
; Enable scaling factor
Extended address
With the following addresses, the address is extended by 1 to 4 digits to obtain a higher number of addresses. In this case,
the value must be assigned using an equality sign "=".
R Arithmetic parameters
H H function
I, J, K Interpolation parameters/intermediate point
M Special function M, affecting the spindle with other options
S Spindle speed
Examples:
R10=6.234 H5=12.1 I1=32.67 M2=5 S1=400
