About this Manual:
The OMRON C200H-NC112 Position Control Unit is a Special I/O Unit for C200H PCs. It is designed
to control positioning actions through pulse train outputs to a motor driver, based on PC programming
and external control inputs.
This manual covers the specifications and procedures necessary for operation and installation. Before
attempting to operate the C200H Position Control Unit, be sure to thoroughly familiarize yourself with
the information contained herein.
During operation, refer to the C200H PC Operation Manual as necessary for programming and sys-
tem details. Note that the term “channel” employed in the C200H PC Operation Manual (and other
earlier manuals) has been replaced by the term “word” in this manual, where it refers to a 16-bit ad-
dress. Wherever the term “channel” (either written in full or abbreviated as “ch”) continues to appear,
whether in earlier manuals, on displays, or on the Units themselves, it can be taken to have the same
meaning as “word.”
