About this Manual:
The C500-NC222-E Position Control Unit in NC221 mode is a Special I/O Unit for SYSMAC C500,
C1000H, and C2000H Programmable Controllers (PCs) that support WRIT (87) and READ (88). This
Position Control Unit (PCU) in NC221 mode is designed to control positioning through voltage outputs
to a motor driver according to PC programming and external control inputs.
This manual covers the specifications and procedures necessary for installation and operation. It also
describes data layouts and examples for communication between the PLC and NC222 Module in
NC221 mode. Before attempting to operate the Position Control Unit, be sure to thoroughly familiarize
yourself with the information contained in this manual. During operation, refer also to your PC Opera-
tion Manual for programming and system details. If you wish to enter data manually via the Teaching
Box, please use this manual for wiring and setup only. Refer to manual number W145 for data entry
and operations.
Section 1 contains information on the features of the Position Control Unit, system configuration, and
an overview of control system principles.
Section 2 contains wiring diagrams and other information necessary for installation and connection of
the Position Control Unit.
Section 3 provides the minimum information necessary to assemble and test a servomotor driver
system using both axes.
Sections 4, 5, and 6 provide information essential for operation, including data configuration, the set-
ting of parameters and positioning actions, communication between the Position Control Unit and the
PC, and the use of status flags.
Section 7 provides a description of command format. It also contains tables of system, servo control,
and data processing commands, including the functions and usage examples for each.
Section 8 shows how to establish the origin, which must be done to establish a reference point be-
fore executing positioning actions.
Section 9 provides a variety of programming examples to illustrate the principles covered in this man-
ual.
Sections 10 and 11 cover external displays and error processing.
The appendices contain specifications, an error code list, and data coding sheets.

WARNING It is extreme important that a PC and all PC Units be used for the specified
purpose and under the specified conditions, especially in applications that can
directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PC System to the abovementioned
applications.
3 Safety Precautions
WARNING Never attempt to disassemble any Units while power is being supplied. Doing so
may result in serious electrical shock or electrocution.
WARNING Never touch any of the terminals while power is being supplied. Doing so may
result in serious electrical shock or electrocution.
4 Operating Environment Precautions
Do not operate the control system in the following places.
•Where the PC is exposed to direct sunlight.
•Where the ambient temperature is below 0°C or over 55°C.
•Where the PC may be affected by condensation due to radical temperature
changes.
•Where the ambient humidity is below 10% or over 90%.
•Where there is any corrosive or inflammable gas.
•Where there is excessive dust, saline air, or metal powder.
•Where the PC is affected by vibration or shock.
•Where any water, oil, or chemical may splash on the PC.
