Depending on the axis of the change, operate the
trackball and Z-ring as follows.
• To change on the X-axis, rotate the trackball
horizontally.
Parameter values increase as you rotate to the right,
and decrease as you rotate to the left.
• To change on the Y-axis, rotate the trackball
vertically.
Parameter values increase as you rotate upward, and
decrease as you rotate downward.
• To change on the Z-axis, rotate the Z-ring.
Parameter values increase as you rotate clockwise,
and decrease as you rotate counterclockwise.
However, if you have pressed the [LOC XYZ]
button or [AXIS LOC] button, the parameter values
increase as you rotate counterclockwise, and
decrease as you rotate clockwise.
To reduce the rate of change of the parameters
(fine mode)
Press the [FINE] button, turning it on.
This enables fine control using the trackball and Z-
ring.

To restrict the change in the transform to a specific
axis, press the [X], [Y], or [Z] button, tuning it on.
This enables the trackball and Z-ring operations on the
selected axis only.
Functions assignable to trackball and Z-ring
operations
Three-Dimensional Parameter
Display
You can check the values of three-dimensional parameters
in the DME menu or on the device control block
(trackball).
Display in the DME menu
The status area of the DME menu shows the three-
dimensional parameters currently controlled by the device
control block.
• When multiple DME channels are selected, this shows
the parameters for the reference channel.
• When both Global and Local are selected, the three-
dimensional parameters are shown for the channel (the
reference channel) for which the button is lit green.
