Division In Set-Up Mode; Division From The Plc - Siemens SINUMERIK 840C Installation Instructions Manual

12.13.1
With this function the indexing positions are traversed incrementally in set-up modes INC and
JOG.
INC mode (incremental dimension)
The indexing axis is traversed incrementally by one division when the traversing key "+" or
"–" is operated. This function is independent of the position on the mode switch. Incremental
dimensions INC 10, 100, 1.000, 10.000 have the same effect as INC 1 in the function "Setup
mode division related".
JOG mode
The indexing axis is moved as for normal JOG mode when the traversing key "+" or "–" is
operated.
If the traversing key "+" or "–" is let go in JOG mode, the axis moves to the next indexing
position to be reached in the direction of travel. If the direction is changed, the next indexing
position is approached in the direction of travel before changing direction.
12.13.2
Division from the PLC is sent via the command channel. The user must specify axis number,
division number, velocity, preparatory functions etc.
Division from the PLC can be executed in NC modes AUT, MDA, JOG, INC and REPOS. The
indexing position can be approached incrementally and absolutely. These are defined in the
preparatory functions in the command channel (G90/G91).
Please refer to the function "Path dimension from PLC" with regard to the conditions for
modes, channels, abort conditions, error behaviour, stop conditions, part program interruption,
part program stop, travel behaviour, travel logic etc. with division from the PLC.
