c. Set movement command to point table
The point table offers movement commands of straight line, arc
and spiral interpolation which can set movement commands in
point table with the paired APS function.
You may set up relevant movement parameter and required
synchronous instruction command as well as save them in the
point table with these three steps. Follow the same steps to save
all graphic sections in point table.
4.10.6.2 Execute Point Table Movement
The controller features two point table which contains 50 buffer
points respectively. You may enjoy point table functions of large
amount of points and free from any practical limits by monitoring
the usages status of buffer point space and reloading these 50
buffer point space repetitively.
A point table movement can be executed in following steps:
a Enable/disable point table function
b Monitor buffer space and fill in the points
c Start /stop point table movement
