The command in this example would cause the controller to consider a difference
between the target and the current position greater than 400nm to be too large. If this
large of an error were detected, the controller would re-engage the move algorithm to
place the position error back inside of the Finish Error (
PC
) limit.
Command: HALT
Shortcut:
\
(the backslash character)
Format:
HALT
Function:
This command will stop all active motors and other actuators too. It’s usually a
Broadcast command
but can be used as a
Non-Addressed Command
as well. When
addressed to a specific card, it stops motion on that card only. Note that to use as a
Non-Addressed Command the full command
HALT
must be used instead of the
shortcut
\
, because
\
is handled quickly in the command parser.
Command: HERE
Shortcut:
H
Format:
HERE [axis]=[position in 1/10 microns]…
Function:
Assign the specified number to the axis’s current position buffer. The unit of
measurement is in tenths of microns. This defines the current position to be a specific
distance from the origin (0), i.e., the origin may change. It’s an
Axis-Specific Command.
DOES NOT WORK FOR PIEZOS AND MICROMIRRORS.
Reply:
If there are no errors, the positive reply
:A
will be sent back from the controller.
Example:
H X=1234 Y=4321 Z
:A
The X position will change to 123.4 microns from the origin, Y will change to 432.1
microns, and the Z will be zeroed.
Command: HOME
Shortcut:
