Properties of type 1 positioning axis
With SW 5 and lower, type 1 positioning axes have the following behavior:
● The block change occurs (NC block finished) when all the path and positioning axes have
● Continuous-path mode (G64) is only possible for path axes if the positioning axes reach
● Programming with
