8.5.3 Skip Operation
Decelerate and stop the current operation step and change to the operation data of next operation step no., then execute
positioning control.
(1) Characteristics of Control
(a) SKIP operation command stops the operation and carries out the operation of next step after executing the command other
than Continuous operation command (Next Move).
(b) This is used in case that the operation mode is End, Keep, Continuous and the operation pattern is in Acceleration,
Constant speed, Deceleration section.
(c) If SKIP operation command is executed in the status that the operation data of next step is not yet set, Error 151 will occur.
(d) When set position data, there would be differences on skip operation command depending on absolute coordinates and
relative coordinates,

■ The goal position of next operation step after skip operation command is executed on absolute coordinates is the same as
the case did not execute skip operation. Therefore, current position positioned by skip operation is P2. (A area and B area
both are same size)
■ When skip operation is executed on relative coordinates, the movement amount between current position and goal
position is the real goal position. Therefore, the goal position is different from the one without continuous operation. The
position positioned by skip operation is P1 + P2.
