Part 1 Specification
(5) Operation by Relative Coordinate Specification
The target position in the position table can also be specified in relative coordinates. This function can be used to repeat
positioning operations at equal pitches.
[1] Example of operation in the positioner 1, 2 mode
The following explains an example of positioning operation repeated at a 50-mm pitch, starting from position No. 1.
The position table shown below is created. End of operation is determined based on the count managed by the PLC.
The zone signal can be used to doubly confirm that operation has ended.
