6-2 Motion Control Instructions
Motion control instructions are used in the user program to execute motion controls for an NJ-series
Controller. These instructions are defined as function blocks (FBs). The motion control instructions of
the MC Function Module are based on the technical specifications of function blocks for PLCopen
motion control. There are two types of motion control instructions: PLCopen-defined instructions and
instructions that are unique to the MC Function Module. This section provides an overview of the
PLCopen motion control function blocks and gives the specifications of the MC Function Module.
Refer to the NJ-series CPU Unit Software User’s Manual (Cat. No. W501) for basic information on the
NJ-series function blocks (FBs).
PLCopen standardizes motion control function blocks to define a program interface for the languages
specified in IEC 61131-3 (JIS B 3503). Single-axis positioning, electronic cams, and multi-axis coordi-
nated control are defined along with basic procedures for executing instructions.
By using PLCopen motion control function blocks, the user program can be more easily reused without
hardware dependence. Costs for training and support are also reduced.
Additional Information
PLCopen
PLCopen is an association that promotes IEC 61131-3. It has its headquarters in Europe and a
world-wide membership. IEC 61131-3 is an international standard for PLC programming.
• The website of headquarters of PLCopen in Europe is http://www.plcopen.org/.
There are three types of motion control instructions. They are given in the following table.
For a list of the instructions that you can use with the MC Function Module, refer to the NJ-series Motion
Control Instructions Reference Manual (Cat. No. W508).
