H1: Manual and handwheel travel
3.4 Handwheel travel in JOG
Figure 3-3
If a stop condition is activated during the handwheel travel, the motion is aborted and the
"Travel request" and "Travel command" NC/PLC interface signals are reset.
Example 3: Handwheel travel with velocity specification, stop condition is an abort criterion
If the handwheel is no longer moved for velocity specification
(MD11346 $MN_HANDWH_TRUE_DISTANCE == 0 or == 2), the "Travel request" NC/PLC
interface signal is reset.
The "Travel request" PLC signal is also reset when the handwheel is deselected.
