Basic Operations
The C200HW-NC113 (one axis), C200HW-NC213 (two axes), and C200HW-
NC413 (four axes) Position Control Units are designed for use with C200HX/
HG/HE-series and C200H/C200HS-series systems.
1-3-1 Position Control
Positioning can be executed with either an absolute value (i.e., to an absolute
position from the origin) or with an incremental value (i.e., to a relative position
from the present position).
There are two methods for positioning: memory operation and direct operation.
Interrupt feeding, in which operation proceeds for the specified amount after an
interrupt input, is also possible.
With memory operation, positioning sequences (i.e., individual positioning
operations, which include data such as positions and speeds) are transferred to
the Position Control Unit in advance, and then positioning is executed from the
Programmable Controller by specifying those positioning sequences by num-
ber.

Depending on the completion code that is set, positioning sequences can be
executed using terminating positioning, automatic positioning, or continuous
positioning. In the following illustrations, “#0” and “#1” indicate positioning
sequence numbers.

With direct operation, positions and speeds are set in allocated areas in the Pro-
grammable Controller’s DM and EM areas, and positioning is executed using
that data.
