10.3.7 Manual Operation Using a Hand Coordinate System
A hand coordinate system can be generated in which the origin is at
the tip of the nozzle, +Zh coincides with the line normal to the nozzle,
+Xh coincides with the arm direction, and the Yh-axis is orthogonal
to both Xh-and Zh-axes. This hand coordinate system can be used for
job and handle feed.

(1) Turning on the hand coordinate system selection signal selects
hand coordinate system mode.
(2) For jog feed in hand coordinate system mode, turning on the jog
feed axis direction signal ±X causes the machine to move in the
±Xh-axis direction. Similarly, turning on the signal for ±Y or ±Z
causes the machine to move in the ±Yh-axis or ±Zh-axis
direction, respectively. To change the hand coordinate system,
turn off the hand coordinate system mode selection signal, and
operate on the α- and β-axes.
(3) For handle feed in hand coordinate system mode, rotating the
manual pulse generator with the X-axis selected as the handle
axis causes the machine to move in the ±Xh-axis direction.
Similarly, rotating the pulse generator with the Y-axis or Z-axis
selected as the handle axis causes the machine to move in the
±Yh-axis or ±Zh-axis, respectively. To change the hand
coordinate system, turn off the hand coordinate system mode
selection signal, and operate on the α- and β-axes.
(4) Set the same value for the manual feedrates on the X-, Y-, and Z-
axes.
