24 ● AP DMC-1400 Series Command Reference
AP FUNCTION: After Absolute Position
DESCRIPTION:
The After Position (AP) 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 absolute position.
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: APn where
n is a signed integer in the range -2147483648 to 2147483647 decimal

RELATED COMMANDS:

EXAMPLES:
#TEST Program B
DP0 Define zero
JG 1000 Jog mode (speed of 1000 counts/sec)
BG Begin move
AP 2000 After passing the position 2000
V1=_TP Assign V1 X position
MG "Position is", V1= Print Message
ST Stop
EN End of Program
HINT: The accuracy of the AP command is the number of counts that occur in 2 samples (2 msec for
TM 1000). Multiply the speed by the time period of 2 samples to obtain the maximum error. AP tests
for absolute position. Use the AD command to measure incremental distances.
