Response with special functions

6.8.1

Dry run (DRY RUN)

The dry run feedrate is also effective for positioning axes unless the programmed feedrate is
larger than the dry run feedrate.
Activation of the dry run feed entered in SD42100 $SA_DRY_RUN_FEED can be controlled
with SD42101 $SA_DRY_RUN_FEED_MODE. See

V1: Feedrates (Page 125)
6.8.2

Single block

Positioning axis type 1
Single-block mode is effective with positioning axes of type 1.
Positioning axis type 2
Positioning axes of type 2 also continue across block limits in single block mode.
Positioning axis type 3
Positioning axes of type 3 also continue across block limits in single block mode.

Examples

6.9.1

Motion behavior and interpolation functions

In the following example, the two positioning axes Q1 and Q2 represent two separate units of
movement. There is no interpolation relationship between the two axes. In the example, the
positioning axes are programmed as type 1 (e.g. in N20) and type 2 (e.g. in N40).
