Specifications Section 2-2
Note (1) Set using the MSKS instruction in direct mode or counter mode.
(2) Prohibiting repeated use of input terminal number
The input terminals are used for input interrupts, quick-response inputs,
high-speed counters, origin searches and normal inputs. Therefore, do
not use the input terminals repeatedly.
A priority is as follows when used repeatedly.
Origin search settings > High-speed counter settings > Input settings.
