8.5.2 Continuous Operation
Execute positioning control changing the current operation step no. to the next one.
(1) Characteristics of Control
(a) When continuous operation command is executed, operating speed is changed into the speed of next operation step
directly.
(b) This command may be used in End, Go on, Continuous mode and used at Acc.,Dec.,Steady speed section.
(c) If continuous operation command is executed in operation, the current operation step no. is changed to the next step no.
and keep operating.
(d) There are differences of operation depending on between absolute coordinates and relative coordinates.

■ The goal positions of continuous operation on absolute coordinates are same, so the goal position is the same as the
position before and after continuous operation. Therefore, the current position positioned by continuous operation is P2. (A
area and B area both are same size)
■ When continuous 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 continuous operation is P1 + P2.
