7.3.4 Fixed-feed operation program
7.3.4 Fixed-feed operation program
This program executes positioning in the address increasing direction according to the specified movement amount
and speed. Execute fixed-feed operation by turning on Fixed-feed start command repeatedly. Use the current value
change function and positioning start in the absolute system. Suppose that parameter setting and OPR were
completed. ( Page 117, Section 7.3.1, Page 119, Section 7.3.2)
(1) Program detail
• As X40 is turned on, the following positioning data are written.
• As X41 is turned on, the module starts fixed-feed operation.
