The motor driver controls either a stepping motor or a servomotor, depending
on whether an open-loop or semiclosed-loop system is employed. (See 1–4
Control System Principles). The stepping motor (or servomotor) controls
some type of positioning device (such as a feed screw, for example). An in-
dependent power supply must be used. Some configurations also require an
Input Unit on the C200H PC to control the motor driver.
Maximum Number of
Special I/O Units per PC
A maximum of 10 Special I/O Units, including Position Control Units,
High-Speed Counters, etc., can be mounted under the same PC, regardless
of whether they are on the CPU Rack, an Expansion I/O Rack, or a rack con-
taining a Remote I/O Slave Unit controlled by the PC. No more than four of
these can be mounted onto any one rack containing a Remote I/O Slave
Unit.
Mounting Location
The Position Control Unit can be mounted to any but the 2 rightmost CPU
Rack slots. Mounting the Unit to either of these slots will prevent you from
mounting devices directly to the PC’s CPU. The back-panel DIP switch must
be set before the Unit is mounted. This switch is inaccessible on a mounted
Unit. (See 2–1 Switch Settings.)
Basic Configuration
Although Unit operation can be indirectly controlled from a host computer,
Remote I/O Master Unit, or other control system or peripheral device, direct
control comes from the program of the PC or from connections to external
inputs (e.g., control panel switches). (A list of Position Control Unit inputs and
outputs can be found under I/O Circuits in 2–2 Wiring.) The following configu-
ration diagrams show only the positioning system itself. Refer to the operat-
ing manuals for other Omron control devices for details on extended control
system operation.
