3.2 G functions

A DIN block with a G function always has the following structure: the letter

"G" is followed by the number of the G function. This is then followed by the

parameters, which are each formed by their address letters and the

corresponding value.

G(number) [address identification(address value)] ...

Possible address identifications are

ƒ X ,Y ,Z ,A ,B, C, U, V, W, x, y, z, a, b, c, u, v, w as designations for axes,

referred to as AXES in the following.

ƒ D, F, H, I, J, K, L, R as G function−specific flow point parameters

ƒ E, O as G function−specific integral parameters

As address values, any flow point numbers alternatively with exponent (e.g.

−23.475e

−3

) are valid for axis addresses and flow point parameters. For all the

others, integers in the range of −32767 to +32767 are allowed.

As an alternative to direct input, all the above−mentioned addresses can also

be programmed indirectly. This is displayed by the specification of "P". The

programming takes place via the P field. Instead of the numerical value, the

index on the P field is then assigned to the address letter.

G0 X=P1000 For X, the value contained in the P field in the index 1000 is then valid.

G0 X=PP1100 For X, the value, whose index is contained P field in the index 1100 is valid

(indicated twice).

A DIN block does not necessarily have to contain a G function. Some of the

functions have a modal effect and do not need to be repeated. The above

specifications are then valid for the rest of the block.
