Discontinuous step / Continuous step

Discontinuous step : It means a step to move off on the aimed step.

The move-off point is a point which the current value (feedback encoder) reaches to the accuracy level (Bit, Distance) designated in the step.

Continuous step : It means a step which doesn't have the move-off point. There are steps that the cornering is possible and impossible step in the continuous step.

Step that the cornering is possible

The step that the cornering is possible shifts after planning the route between two steps. The step that the cornering is possible is the same as following. There are P(Interpolation OFF), L(Straight Line Interpolation) and C(Circular Arc Interpolation) in the interpolation type which supports in the Hi4 controller. The continuous system which supports the cornering in these types is L-L, L-J, J-L, C-J, J-C and J-J.

Only, the step which the coordinate system changes( for example, such case as it shifts for the direction of the positioner motive interpolation step from the robot tool interpolation ) is excluded in the cornering step.

② The locus of L-L cornering

The L-L cornering is a method that plans the locus with a circular arc between two locuci of continuous straight line. It corners describing the locus of circular arc that circumscribes on the circle of accuracy range from two straight lines and a point which is applicable to step1 in the following figure. When replaying in the automatic mode, the locus should be checked in advance due to shifting without reaching to designate step.
