Product Overview

The Omron CJ1W-SRM21 is a specialized servo relay module designed for CJ1 series programmable logic controllers, enabling sophisticated position control and motion coordination capabilities. This module serves as an interface between the CJ1 PLC CPU and Omron SmartStep and other servo drive systems, providing high-speed pulse output for precise positioning applications. The CJ1W-SRM21 supports multiple positioning modes including point-to-point positioning, speed control, and torque control, making it suitable for a wide range of motion control applications in packaging, assembly, and material handling equipment. The module can control up to four axes of motion with independent positioning parameters, allowing complex multi-axis coordination and synchronization. With built-in high-speed counter inputs, the module can interface with encoders for position feedback and closed-loop positioning control. The CJ1W-SRM21 integrates seamlessly with CX-Programmer and CX-Positioner software tools, enabling intuitive configuration of motion profiles, positioning parameters, and sequence programming. The module supports both linear and S-curve acceleration/deceleration profiles, ensuring smooth motion and reduced mechanical stress on driven equipment. Applications include pick-and-place systems, indexing tables, cutting machines, and any application requiring precise positioning control with PLC-based sequencing and logic. The module ability to execute positioning sequences independently of the PLC scan time ensures high-speed, deterministic motion control performance.
