Position Table

The position table enables a set Move program sequence containing variable
positions to be run.
Up to 50 positions can be stored in the position table that can be queried by
Move commands. The position table entries can be evaluated on the basis of
absolute or relative Move commands.
The position table can be downloaded. As an alternative to this, individual
entries can be written or "taught" as absolute or relative positions with the
current position.
2.1.2.12.3.1

Teaching of Positions

Teaching of positions using the mailbox command POS_TABLE_TEACH
allows the current actual value to the saved in the position table so that it is
available as a target for a Move task.
