is replaced by
G700
, alarm 61000 (
N220
) does not occur.
Synchronized actions
To ensure in the case of synchronized actions that the current part program context does not determine the
measuring system used in the condition and/or action part, the measuring system must be defined within the
synchronized action (condition and/or action parts). This is the only way of achieving defined, reproducible
behavior in the use of length-related data within a synchronized action.
Example 1
The measuring system is not specified within the synchronized action. Therefore, the traversing motion of the X
axis takes place in the measuring system of the configured initial state:
Example 2
The "metric" measuring system is explicitly programmed with
G71
within the synchronized action. This means the
traversing motion of the X axis takes place in the metric measuring system:
