About this Manual:
This manual describes the features, specifications, and operation of the CS1W-MC421/221 Motion
Control Unit and includes the sections described below.
Please read this manual and the other manuals related to the CS1W-MC421/221 Motion Control Unit
carefully and be sure you understand the information provided before attempting to install and operate
the Motion Control Unit.
Refer to
1-12 Overview of Version 1 Upgrades
for an outline of the new features added to the CS1W-
MC421-V1 and CS1W-MC221-V1. (“-V1” is omitted in this manual.)
Section 1
explains the features and system configuration of the CS1W-MC421 and CS1W-MC221
Motion Control Units (MC Units), and outlines some of the differences with the features of the earlier
C200H-MC221 MC Unit.
Section 2
describes the MC Unit components and provides the information required for installing the
MC Unit.
Section 3
describes the data contained within the MC Unit.
Section 4
describes the means used to store data of various types and explains how data is trans-
ferred between the MC Unit and the CPU Unit.
Section 5
describes the ways in which data can be transferred between the CPU Unit and the MC
Unit, including using the IOWR/IORD instructions, using the PLC Interface Area, and using dedicated
bits/flags in memory.
Section 6
explains the basic positioning operations executed by the MC Unit.
Section 7
describes using the G language to program motion control in the MC Unit.
Section 8
provides examples of G-language programming for the CS1W-MC421/221.
Section 9
explains how to search for and establish the origin using either an incremental encoder or
an absolute encoder, and gives a general overview of absolute encoders.
Section 10
describes the teaching function. This function can be used to teach new positions by mov-
ing to a given position and then reading the present position of each axis as position data.
Section 11
explains how to get started using the MC Unit. It provides information on the MC Unit’s
startup procedures, system configuration, wiring, creating I/O tables, inputting MC programs, creating
ladder programs, transferring data, saving data, and conducting trial operation.
Section 12
explains the troubleshooting procedures to be employed if problems should occur in MC
Unit operation.
Section 13
explains the maintenance and inspection procedures that must be followed to keep the MC
Unit operating in optimum condition. It includes instructions on the proper procedure to follow when
replacing an MC Unit, and precautions to observe when replacing a Servomotor.
The
Appendices
provide MC Unit performance information, control bit/flag timing charts, MC program
coding sheet, sheets for recording system parameter settings, and position data coding sheet.
!WARNING
Failure to read and understand the information provided in this manual may result in per-
sonal injury or death, damage to the product, or product failure. Please read each section
in its entirety and be sure you understand the information provided in the section and
related sections before attempting any of the procedures or operations given.
