(4) 2 axes linear interpolation continuous operation with circular arc insertion
When the operation method is set as “continuous” and the direction of movement changes rapidly, machine is
possible to be damaged. When you need not position the object to the target position precisely, user can insert
„circular interpolation operation‟ between two trajectories to make operation softer and smoother.
(a) Operation order
1) Confirm whether to execute 2 axes linear interpolation continuous operation with circular arc insertion. It can
be set in
「
Arc insertion
」
of extended parameter.
Setting items Setting value Description
Arc insertion
0 : Don‟t insert
In case of 2 axes linear interpolation continuous
operation, it
doesn‟t insert arc
1 : Insert arc cont.
In case of 2 axes linear interpolation continuous
operation, it inserts arc
2) It checks the position where arc will be inserted and resets the starting position of circular interpolation
(target position of linear trajectory 1) and the target position (starting position of linear trajectory 1). The
position where circular arc will be inserted can be set in
「
Arc insertion position
」
of extended parameter.
Setting items Setting value Description
Arc insertion position 0 ~ 2147483647
Set the position where circular arc will be
inserted. This value means the incremental
distance from the target position of linear
trajectory 1.
3) After linear interpolation to the starting position of circular arc to be inserted, it executes circular interpolation
at the same speed as linear interpolation. After finishing the circular interpolation, it executes linear
interpolation to the target position of the next operation step again at the same speed.
