14.27.3 Detailed Specifications

When a hypothetical coordinate system is selected using a PLC signal during manual feed (jog, incremental or handle mode)
or at handle interrupt in automatic operation, manual feed can be performed in the selected coordinate system.
This function has two feed modes: "Feed in hypothetical coordinate system" and "Rotation with the tool tip as the center".
"Feed in hypothetical coordinate system" is applied to a linear axis travel command. The manual feed is carried out in
hypothetical coordinate system using the three linear axes.
Tool tilt (feed direction after A axis rotates by +45° and C by -90°) Table tilt (after B axis rotates by -45° and C by +90°)

Rotation with the tool tip as the center is applied to a rotary axis travel command. The manual feed is carried out using the
rotary axes and the three linear axes so that the positional relationship between the workpiece and tool tip can be kept.

Select the hypothetical coordinate system from among the table, feature or tool axis coordinate system.
If not selected, standard manual feed and interruption are carried out in the machine coordinate system.

14.27.3.1 Requirements for 3-Dimensional Manual Feed

When all of the following requirements are met, the 3-dimensional manual feed is carried out.
 The rotary axis configuration parameter "#7912 NO_MANUAL" is "0" (3-dimensional manual feed is valid).
 Selected mode is either jog, incremental or handle.
 A hypothetical coordinate system is being selected. Or,"Rotation with the tool tip as the center" is being selected.
 Not in a state where axis travel is disabled; such as during alarm occurrence, during manual interlock, and when the axis
has reached the soft limit, etc.
