OMRON CJ1W-NCF71 Position Control Units

OMRON CJ1W-NCF71

Introducing a Position Control Unit that can control up to 16 axes across

a MECHATROLINK-II* high-speed field network. With it, every aspect of multi-axis

systems from machine design to future expansions can be changed quickly and simply

OMRON has developed a whole new environment that

seamlessly integrates different control devices and

networks over the entire life cycle of equipment and

machines, ranging from design and startup to operation

and maintenance. The system will still be viable as new

systems are developed and new control devices and

controllers become available. It all begins with OMRON

Standard Libraries.

OMRON Standard Libraries are software applications that customers can

load into their system and use without modification. The OMRON FB

Library and Smart Active Parts (SAPs) Library are available now. These

libraries simplify the software developed for interface components

between Programmable Controllers (PLCs) or Programmable Terminals

and various other control devices. They also improve the quality of the

software by using standardized software components.

The OMRON FB Library contains functional components for

Programmable Controllers (PLCs). These components can be used by

customers to produce finished programs that interface with various

control devices in much less time. Since the components are

standardized, they also improve the quality of the finished programs.

The Smart Active Parts (SAPs) Library, formerly known as the Device

Library, consists of screens with functions for Programmable Terminals.

SAPs can be used on screens developed by customers to produce

finished screens that interface with various control devices in much less

time. Since the components are standardized, they also improve screen

quality.

Origin search: Establishes the origin using the specified search method.

Present position preset: Changes the present position to a specified position to establish the origin.

Origin return: Returns the axis from any position to the established origin.

Absolute encoder origin: Establishes the origin using a Servomotor that has an absolute encoder, without having to use an origin search.

Outputs pulses at a fixed speed in the CW or CCW direction.

Performs positioning by moving the axis a fixed amount when an external interrupt input is received while the axis is moving.

Performs speed control by sending a command to the Servo Driver speed loop.

Performs torque control by sending a command to the Servo Driver current loop.

Any of the following can be set: a trapezoidal (linear) curve, an exponential curve, or an S-curve (moving average).

Restricts the output torque during axis operation.

Multiplies the axis command speed by a specified ratio. Override: 0.01% to 327.67%

Reads and writes the Servo Driver parameters from the ladder program in the CPU Unit.

Monitors the control status of the Servo Driver, such as the command coordinate positions, feedback position, current speed, and torque.

Sets limits on the software level applied to the positioning range of axis operations.

Compensates for the amount of play in the mechanical system according to a set value.
