CJ1M Programmable Controller

Small yet Powerful, and Now in More Cost-efficient Models

Lineup of Low-end CPU Units with Basic Functions Plus High Added Value

• Program capacity of 5 Ksteps and up to 160 I/O points: For small-scale machine control yet including all the basic functions of the CJ Series.

• Standard features include a Memory Card interface and RS-232C port for serial communications.

• CPU Units with Pulse I/O have built-in high-speed counter inputs and pulse outputs for greater added value for machines.

Encoder Inputs for Two Axes

Measure Rotation Data  

Four Interrupt of Quick-response Inputs

High-precision Pulse with Variable Duty Factor (PWM) Output  

High-speed Pulse Outputs for Two Axes

Wide variety of pulse output functions, such as 100-kHz isokinetic or trapezoidal acceleration/deceleration for speed control, origin searches, trapezoidal positioning with acceleration/deceleration, interrupt feeding, and changing the target position during positioning.

Acceleration/Deceleration with Shock Suppression 

Functions indicated as new are supported by CX-Programmer version 4.0 or later.

Fast, Small and Seamless!

The CJ1 Series has expanded to meet the requirements of compact and general-purpose devices and to support the downsizing of machinery with greater added value.

Contributing to Machine Downsizing

The CPU Unit is half the size of the CJ1G/CJ1H CPU Unit.

Built-in Positioning Functions

Lineup includes CPU Unit with built-in pulse input/output functions.  This CPU Unit can be used for simple positioning, allowing further downsizing.

Combining Units with Greater Efficiency

The CJ1M does not require a backplane allowing Units to be combined flexibly.  Despite not having a backplane, it is still possible to leave words empty for future expansion.  Systems can be expanded to include more I/O without making any changes to existing I/O word allocations.

More freedom and higher precision pulse I/O control provides greater added value to machines.
