6.1.3 Path-jog mode.
The "path jog" mode acts when the switch is in one of the continuous or incremental jog positions.
This feature may be used to act upon the jog keys of an axis to move both axes of the plane at the
same time for chamfering (straight sections) and rounding (curved sections). The CNC assumes
as "Path jog" the keys associated with the X axis.
The data to define the paths is defined using the following variables.
• For a linear path, indicate the path angle in the MASLAN variable (value in degrees between
the linear path and the first axis of the plane).
• For an arc, indicate the arc center coordinates in the MASCFI, MASCSE variables (for the first
and second axes of the main plane).
Variables MASLAN, MASCFI and MASCSE may be read and written from the CNC, DNC and PLC.
Operation in path-jog mode
The "path jog" mode is only available with the X axis keys. When pressing one of the keys associated
with the X axis, the CNC behaves as follows:
The rest of the jog keys always work in the same way, whether "path jog" is on or off. The rest of
the keys move only the axis and in the indicated direction.
The movements in path-jog may be aborted by pressing the [STOP] key or setting the jog switch
to one of the handwheel positions.
Considerations about the jog movements
This mode assumes as axis feedrate the one selected in jog mode and it will also be affected by
the feedrate override switch. If F0 is selected, it assumes the one indicated by machine parameter
"JOGFEED (P43)". This mode ignores the rapid jog key.
Path-jog movements respect the travel limits and the work zones.
This feature must be managed from the PLC. This feature is usually activated and deactivated by
means of an external push-button or a key configured for that purpose, as well as the selection of the
type of path.
