DMC-1400 Series Command Reference AR ● 25
AR FUNCTION: After Relative Distance
DESCRIPTION:
The After Relative (AR) command is a trippoint used to control the timing of events. This
command will hold up the execution of the following command until one of the following
conditions have been met:
1. The commanded motor position crosses the specified relative distance from either
the start of the move or the last AR or AD command.
2. The motion profiling on the axis is complete.
3. The commanded motion is in the direction which moves away from the specified
position.
The units of the command are quadrature counts. The motion profiler must be on or the
trippoint will automatically be satisfied.
ARGUMENTS: ARn where
n is unsigned integer in the range 0 to 2147483647 decimal.

HINT: AR is used to specify incremental distance from last AR or AD command. Use AR if multiple
position trippoints are needed in a single motion sequence.
