To exercise motion control and external I/O equipment control, the motion system
consists of the CPU module, main base unit and various modules such as the
power supply module, pulse generator/synchronous encoder modules and I/O
modules. Each module must be selected, set, and connected according to the
system specifications. Further, the motion system can connect to the graphic
operation system (GOT), exercise information control using a personal computer,
and connect to a control network which uses the MELSECNET so that the system
may be configured up to meet various applications.
Based on the following system configuration, this section explains the ways to
select the modules needed in designing the motion system and to set and connect
the modules, and the designing precautions.
