CD
FUNCTION: Contour Data
DESCRIPTION:
The CD command specifies the incremental position on contour axes. The units of the command
are in encoder counts. This command is used only in the Contour Mode (CM). The
incremental position will be executed over the time period specified by the command DT
(ranging from 2 to 256 servo updates) or by the = operand.
ARGUMENTS: CD n,n,n,n,n,n,n,n = m
or
CDA=n
where
n is an integer in the range of +/-32762.
m (optional) is an integer in the range 0 to 8.
n = m = 0 terminates the Contour Mode.
m = 1 through 8 specifies the time interval (DT) of 2m samples.
By default the sample period is 1 msec (set by the TM command); with m = 1, the time interval
would be 2 msec.
Note: The command CD0=0 will assign a variable CD0 the value of 0. In this case the user must
have a space after CD in order to terminate the Contour Mode correctly. Example: CD 0=0
will terminate the contour mode for the X axis.
