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.
