Technical Overview

The Omron CK3W-AX1515N is an advanced 4-Axis Interface Unit designed for the modular CK3M/CK5M Programmable Multi-Axis Controller series. It provides precise high-speed multi-axis control via analog commands, supporting a True DAC (Digital-to-Analog Converter) output for highly smooth motion profiles. This unit seamlessly integrates up to four axes per module and can connect directly to analog input servo drives. Engineered with robust compatibility, it supports digital quadrature, pulse, and serial encoders. To augment machine control synchronization, the CK3W-AX1515N features an NPN output configuration and includes 16 built-in general-purpose digital inputs and 16 digital outputs.

Industrial Applications

1. Precision CNC Machining & Milling Contouring

Utilizing the CK3W-AX1515N's True DAC analog output, the Omron CK3M controller provides exceptionally smooth, high-resolution velocity and torque commands directly to analog servo drives. This configuration is critical for mitigating machining surface imperfections and reducing quantization noise typically seen with standard pulse-train outputs on multi-axis setups.

Problem Solved

Achieving nanometer-level precision and ultra-smooth complex contouring on multi-axis CNC machines where discrete digital lag or jitter can compromise surface finish quality.

2. High-Speed Web Processing and Packaging Synchronization

The unit integrates its multi-axis analog control with digital quadrature or serial encoders to easily capture a master-axis position with virtually zero latency. It processes these inputs alongside its 16 built-in general-purpose NPN digital I/Os, allowing for immediate high-speed triggering of cutting or sealing mechanisms across up to 4 slave axes.

Problem Solved

Perfectly synchronizing multiple continuous moving axes with a master encoder signal while simultaneously managing local high-speed sensor triggering during rapid web manufacturing.

3. Semiconductor Wafer Handling Robotics

In delicate pick-and-place systems inside clean rooms, erratic step-changes in motor voltage can cause mechanical resonance or wafer damage. The True DAC analog interface operates seamlessly with accurate serial absolute encoders to command precise movements, ensuring vibration-free, ultra-smooth acceleration profiles in a compact IP20 DIN-rail form factor.

Problem Solved

Preventing mechanical resonance, vibration, and resulting breakage of delicate materials by demanding highly smooth and continuous servo commands instead of jagged pulse adjustments.
