Galil DMC-1800, DMC-1700 Command Syntax - Binary, Coordinated Motion with more than 1 axis, 1X80

PR ,,,4000	Specify W only as 4000
PR 2000, 4000,6000, 8000	Specify X Y Z and W
PR ,8000,,9000	Specify Y and W only
PR ?,?,?,?	Request X,Y,Z,W values
PR ,?	Request Y value only

The DMC-1700/1800 provides an alternative method for specifying data. Here data is specified individually using a single axis specifier such as X,Y,Z or W. An equals sign is used to assign data to that axis. For example:

PRX=1000	Specify a position relative movement for the X axis of 1000
ACY=200000	Specify acceleration for the Y axis as 200000

Instead of data, some commands request action to occur on an axis or group of axes. For example, ST XY stops motion on both the X and Y axes. Commas are not required in this case since the particular axis is specified by the appropriate letter X Y Z or W. If no parameters follow the instruction, action will take place on all axes. Here are some examples of syntax for requesting action:

BG X	Begin X only
BG Y	Begin Y only
BG XYZW	Begin all axes
BG YW	Begin Y and W only
BG	Begin all axes

1X80

For controllers with 5 or more axes, the axes are referred to as A,B,C,D,E,F,G,H. The specifiers X,Y,Z,W and A,B,C,D may be used interchangeably:

BG ABCDEFGH	Begin all axes
BG D	Begin D only

Coordinated Motion with more than 1 axis

When requesting action for coordinated motion, the letter S or T is used to specify the coordinated motion. This allows for coordinated motion to be setup for two separate coordinate systems. Refer to the CA command in the Command Reference for more information on specifying a coordinate system. For example:

BG S	Begin coordinated sequence on S coordinate system.
BG TW	Begin coordinated sequence on T coordinate system and W axis

Command Syntax - Binary

Some commands have an equivalent binary value. Binary communication mode can be executed much faster than ASCII commands. Binary format can only be used when commands are sent from the PC and cannot be embedded in an application program.
