Position command
You can use the Position command in any PR paths (PR#1 - PR#99). It is marked as “Position”,
and includes the options to “Stop once position control completed” and “Load the next path
once position control completed”. The only difference is that “Load the next path once position
control completed” shows an arrow pointing to the next PR. See Figure 7.1.4.4.

Figure 7.1.4.4 Position command display
(1) Command execution type (property): a Position command can interrupt (INS) the previous
PR path. If the Interrupt function is enabled, it displays (I); if not, no information is
displayed. The Position command can overlap (OVLP) the next PR path. Set the delay
time to 0 when you use the Overlap function. If the Overlap function is used, it displays
(O); if not, no information is displayed.
(2) Delay time (DLY): determined by shared PR parameters. It is defined by a command from
the controller. The servo drive starts counting the delay time once the motor reaches the
target position.
(3) Target position: the set target position.
(4) Position command type: “ABS” means absolute positioning; “REL” means relative
positioning; “INC” means incremental positioning; “CAP” means high-speed position
capturing.
(5) Target speed: determined by shared PR parameters.
(6) Acceleration time (ACC): determined by shared PR parameters; length of time to reach the
target speed from stopped.
(7) Deceleration time (DEC): determined by shared PR parameters; length of time to
decelerate from target speed to stopped.
