SECTION 1
Introduction
The C500-NC222-E Position Control Unit (PCU) in NC221 mode is a Special I/O Unit that receives positioning commands
from the Programmable Controller (PC) and outputs control voltages to two servomotor drivers. Since it outputs control volt-
ages rather than pulses, it can be directly connected to any of a variety of servomotor drivers. You can use it with the C500,
C1000H, or C2000H PC.
Each of the two servomotor drivers controls a servomotor which rotates one of the two positioning axes. The Position Control
Unit can control the axes independently or simultaneously. Both straight-line and circular arc interpolation are also possible.
This section describes the basic features, components, and operation of the Position Control Unit in NC221 mode, as well as
the basic configuration and principles of positioning control systems. Reading this section first will give you a familiarity with
the essential terminology used in this manual and an understanding of the fundamentals necessary for successful operation.
