Ctrl Command home_position_xyz
Function activates the home jump mode (for the X, Y and Z axes) and defines the home position
Restriction If the 3D option is not enabled or no 3D correction table has been assigned (see
select_cor_table), then the command will have the same effect as home_position.
However, microvectorization will be calculated like a 3D command and hence will
influence the effective jump speed in the XY plane.
Call
home_position_xyz( XHome, YHome, ZHome )
Parameters
XHome,
YHome,
ZHome
Comments • Except for the additional motion in the third dimension, this command functions simi-
larly to the
• The home jump mode is deactivated with the command
home_position_xyz( 0, 0, 0 ) or home_position_xy( 0, 0 ).
• The X and Y axes can be controlled with 20-bit resolution, the Z axis with 16-bit resolu-
tion. The RTC
upscales Z coordinate values internally to 20-bit values, so that the three dimensions of
space can be handled equivalently in terms of the supplied jump speed value.
• The DirectMove3D parameter of the
of Z-axis motion (linear or with stepwise correction).
• During calculation of the Z output value to the scan system, any previously defined
offset to the Z coordinate and focal length is taken into account (see

List Command
Function Conditional command execution: This command immediately executes the directly
following list command, if the current IOvalue at the EXTENSION 1 connector's 16-bit
digital input port meets the following condition:
((IOvalue AND Mask1) = Mask1) AND (((not IOvalue) AND Mask0) = Mask0)
(i.e. if the bits specified in Mask1 are 1 and the bits specified in Mask0 are 0). Otherwise, the
next list command is skipped over.
Call
if_cond( Mask1, Mask0 )
Parameters
Mask1,
Mask0
