4. OPERATION

(e) Interrupt positioning command (ITP)

POINT

When Interrupt positioning (ITP) is used for positioning, a stop position
differs depending on the servo motor speed provided when the "ITP"

command is enabled.

When the "ITP" command is used in a program, the axis stops at the position by the set value
farther from the position where any of Program input 1 to 3 (PI1 to PI3) turned ON.
If the move command set with the "MOV", "MOVI", "MOVA" or "MOVIA" command is less than the
set value of the "ITP (set value)" command, the program proceeds to the next step without
executing the "ITP (set value)" command.
When using the "ITP" command, always place the "SYNC" command immediately before the "ITP"
command.
