84 ● DT DMC-40x0 Command Reference
DT
FUNCTION: Delta Time
DESCRIPTION:
The DT command sets the time interval for Contour Mode. Sending the DT command once will
set the time interval for all contour data until a new DT command (or CDm=n) is sent.
ARGUMENTS: DT n where
n is an integer in the range 0 to 8.
n = 1 through 8 specifies the time interval of 2n samples.
n = -1 allows a pre-load of the contour buffer or to asynchrounsly pause the contour buffer. DT-1
during countor mode will pause the contour buffer (and commanded movement). A positive
DT will resume contour mode from paused position of buffer.
By default the sample period is 1 msec (set by the TM command); with n=1, the time interval
would be 2 msec
n = ? Returns the value for the time interval for contour mode.
USAGE: DEFAULTS:
While Moving Yes Default Value 1
In a Program Yes Default Format 1.0
Command Line Yes
Controller Usage ALL CONTROLLERS
OPERAND USAGE:
