The module occupies 20 words in the CJ Series Special I/O area and communicates with the PLC CPU through the CJ system bus.

Working Principle of OMRON CJ1W-NC413

The OMRON CJ1W-NC413 operates by receiving motion commands from the PLC CPU and generating pulse signals for connected motion devices.

When a positioning command is issued from the PLC program, the CJ1W-NC413 calculates the required movement parameters, including target position, movement speed, and acceleration or deceleration settings.

The unit then outputs pulse signals to servo drives or stepping motor drivers. The connected motor system converts these pulse signals into mechanical movement.

The number of pulses determines the movement distance, while pulse frequency determines the motor speed. Through accurate pulse generation, the module enables precise positioning control for industrial machinery.

This architecture allows PLC systems to manage complex mechanical movements while maintaining centralized control through ladder programming.
