42 • Chapter 5 Command Basics DMC-1000
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
1080
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 is used to specify the coordinated motion.
For example:
BG S Begin coordinated sequence
BG SW Begin coordinated sequence and W axis
Program Syntax
Chapter 7 explains the how to write and execute motion control programs.
Controller Response to DATA
The DMC-1000 returns a : for valid commands.
The DMC-1000 returns a ? for invalid commands.
For example, if the command BG is sent in lower case, the DMC-1000 will return a ?.
:bg <enter> invalid command, lower case
? DMC-1000 returns a ?
When the controller receives an invalid command the user can request the error code. The error code
will specify the reason for the invalid command response. To request the error code type the
command: TC1 For example:
