TNC 406/TNC 306 12 Jog increment positioning 2/97
12 Jog increment positioning
In the operating mode "Electronic Handwheel" the jog increment feature may be activated by the
PLC program. By pressing one of the axis direction keys (e.g. X+) the corresponding axis will move
by the programmed increment (0.001 to 50mm).
Increment positioning is enabled by the PLC marker M2498. In "Electronic Handwheel" mode the
prompt "Increment" appears in the line above that of "Interpolation Factor."
Normally, jog increment positioning is initiated by the axis direction keys. In order to move only one
increment per press of a key, the edge evaluation of inputs function in the PLC is used. (See the
chapter "PLC Programming", section "Edge Evaluation of PLC Inputs.") The continuous jog function of
the axis direction keys must also be inhibited in "Electronic Handwheel" mode.
