MotionSuite™ Series Machine Controller Programming Manual Chapter 5: Variables (Registers)

5.1 Outline
In this section, an outline of the variables is described.
5.1.1 Variable Overview
In motion programs the variables can be used to describe values instead of directly
giving the values. When using variables, the motion program uses the values stored
in an area reserved for variables.
! ! ! ! Variable (Register) Type
Motion programs can use the following 7 types of registers (described in the following
table) as variables. The S, M, I, O, and C registers are called global variables which can be
used in both motion programs and ladder programs. The # and D registers are called local
variables which are only capable of referencing within an individual program. However,
the local variables are secured in program memories; they take space from the programs.

S System Register
SB, SW, SL,
SFnnnnn SW00000
~SW01023
Registers prepared in the system. The register
number nnnnn is displayed with a decimal.
When the system starts, the
SW00000~SW00049 is cleared to 0.

Registers used for the I/F between each DWG.
The register number nnnnn is displayed with a
decimal.
I Input Register
IB, IW,
IL, IFhhhh IW0000
~IW07FF
Registers used for I/O module input data. The
register number hhhh is displayed with a
hexadecimal. If a register number is after C000,
it is used for interface with the servo
monitoring parameters.
O Output Register
OB, OW,
OL,
OFhhhh
OW0000
~OW07FF
Registers used for I/O module output data. The
register number hhhh is displayed with a
hexadecimal. If a register number is after C000,
it is used for interface with the servo setting
parameters.
C Constant Register
CB, CW,

CW00000
~CW4095
Registers that can be referenced only by a
program. The register number nnnnn is
displayed with a decimal.
