Travel Request - Siemens SINUMERIK Series Function Manual

H1: Manual and handwheel travel
3.4 Handwheel travel in JOG
Interruption of a traversing motion
When a stop command is issued, the distance-to-go is saved and the handwheel pulses are
collected. When the stop condition no longer applies, the resulting distance is traversed.
Abort of a traversing motion
When a stop command is issued, the distance-to-go is deleted and the handwheel pulses
are ignored (i.e. not collected) until the stop condition no longer applies.

Travel request

The following examples are intended to illustrate the method of operation of the "Travel
request" NC/PLC interface signal.
Example 1: Handwheel travel with distance specification, stop condition is not an abort criterion
If a stop condition that is present is not an abort criterion (see
MD32084 $MA_HANDWH_STOP_COND or
MD20624 $MC_HANDWH_CHAN_STOP_COND) during handwheel travel with distance
specification (MD11346 $MN_HANDWH_TRUE_DISTANCE == 1 or == 3), then the output of
the NC/PLC interface signals "Travel request" and "Travel command" corresponds to the
behavior in the two figures below.
