1 Turn on the manual operation in hand coordinate system signal
(G226#3 HNDCD).
2 Jog feed
Each axis moves in the ± Xh-axis direction using jog feed axis
direction signal ± X. They also move in the ± Yh-axis direction using
a ± Y signal and the ± Zh-axis direction using a ± Z signal.
For the jog feed in the hand coordinate system, one-axis operation
(including α and β axes) is performed at the same time. When jog feed
axis direction signal ± α and ± β are specified, the rotarion axis
operates in the nozzle tip fixed mode. If execution of the rotation axis
command stops, the hand coordinate system is updated to a new
coordinate system.
A linear axis command is executed in the updated hand coordinate
system.
3 Handle feed
Each axis can be moved in the ± Xh-axis direction using a manual
pulse generator when manual handle feed axis select signal HX
turned on. They also move in the ± Yh-axis direction using ± HY
signal and the ± Zh-axis direction using a ± HZ signal.
H4 (4th axis: α axis) and H5 (5th axis: β axis) handle feeds cannot be
accepted when hand coordinate mode select signal HNDCD is set to 1.
To move the α and β axes by the handle feed, set the HNDCD signal to
0. When manual handle feed axis select signal H4 or H5 is selected, set
a PMC ladder so that the HNDCD signal is “0”. This facilitates the
operation.
Set all the X–, Y–, and Z–axes to the same manual feedrate.
