2.1 Tool axis direction handle/JOG/incremental feed
Overview
In the tool axis direction handle/JOG/incremental feed, the tool is moved in the
tool axis direction.
Tool axis direction
The tool axis direction is a direction which is specified in parameter No.19697
when the rotary axes for controlling the tool are at 0 degrees. When the rotary
axes for controlling the tool rotate, the tool axis direction is changed corresponding
to the angle of the rotary axis.

Tool axis direction handle feed
The tool axis direction handle feed is enabled when the following four conditions
are satisfied:
(1) Handle mode is selected.
(2) The tool axis direction feed mode signal (ALNGH) is set to "1". And the table
base signal (TB_BASE) is set to "0".
(3) The state of the first manual handle feed axis selection signals (HS1A-HS1D) to
make the tool axis direction handle feed mode effective is set in parameter
No.12310.
(4) The value of parameter No.12310 is corresponding to the first manual handle
feed axis selection signals (HS1A-HS1D).
Amount of movement
The tool is moved in the tool axis direction by the rotation of the manual pulse
generator.
Feedrate clamp
Feedrate is clamped so that the feedrate of each axis does not exceed the manual
rapid traverse rate for each axis (parameter No.1424).
