will cause axis 2 to move in the positive direction and axis 3 to move in the negative direction. When both
axes have stopped moving, the WS command will cause a 0.3 second delay after which the remainder of
the command line will be executed.
After going through this complex motion 5 times, it can be repeated another 5 times by simply entering a
return character. All command strings are retained by the controller until some character other than a
return is entered. This comes in handy for observing the position display during a move.
If you enter:
1MR1000 <return>
1TP
<return>
(return)
(return)
(return)
(return)
The controller will respond with a succession of numbers indicating the position of the axis at that time.
Many terminals have an "auto-repeat" feature that allows you to track the position of the axis by simply
holding down the return key.
Another way to monitor the progress of a movement is to use the
Repeat
command without a value. If
you enter:
1MR10000 <return>
1TP,RP
<return>
The position will be displayed continuously. These position reports will continue until stopped by the
operator pressing the Escape key.
While the controller is executing commands, it will ignore all alphanumeric keys that are pressed. The
user can abort a currently executing command or string by pressing the escape key. If the user wishes
only to pause the execution of commands, the user should press the space bar. In order to restart
command execution press the space bar again. If after pausing command execution, the user decides to
abort execution, this can be done by pressing the escape key.
