4.4.9 Pitch Feeding by Relative Coordinate Specification
For the target position in the position table, relative coordinate specification is also available. Therefore, it can be
used in constant-pitch positioning (constant-pitch feeding).
(1) Operation example in the position no. The following is the description of an example of positioning
with a 50 mm pitch from position No. 1. Create a position table as shown below. Operational
completion is judged by PLC’s executing count control. The combined use of the zone signal
allows a double check specification mode.
