Product Overview: Nidec Control Techniques SM-CANOPEN Module
The SM-CANOPEN is a high-performance fieldbus option module designed for the Unidrive SP, Commander SK, and Digitax ST drive families by Nidec Control Techniques. This module allows for seamless integration of industrial drives into CANopen networks, facilitating high-speed communication and decentralized control. It is an essential component for machine builders who require standardized interoperability between drives, PLCs, and other automation peripherals in complex motion control environments.
High-Speed Communication and DS301 Profile
The SM-CANOPEN module supports the DS301 profile, ensuring full compatibility with a wide range of master controllers. It allows for flexible data rates up to 1 Mbps, making it suitable for applications that demand rapid feedback and precise synchronization. The module fits into any of the drive’s available Solutions Module (SM) slots, and it is automatically recognized by the drive’s internal firmware. With support for both PDO (Process Data Objects) and SDO (Service Data Objects), the SM-CANOPEN provides comprehensive access to drive parameters and real-time control registers.
