Upgrade expands functional safety support for linear motors and linear axes

Kollmorgen Corporation releases the next update for the SafeMotion Monitor (SMM) firmware: SMM 3.0. This upgrade expands functional safety support for linear motors and linear axes, helping machine builders implement functional safety in applications ranging from semiconductor manufacturing to battery production and industrial automation that require safety.

Integrated into AKD2G servo drives and the Kollmorgen 2G Motion System, SMM 3.0 continues to work with all motors that feature any HIPERFACE DSL® rotary-safe feedback system. It also allows the AKD2G drive to now support EnDat 2.2 safe feedback systems to better serve the growing demand for high-performance safety solutions in precision motion control.

The EnDat 2.2 safe protocol, now supported by ADK2G drives and 2G Motion System, delivers dual independent positioning for robust error detection, high-speed serial data transmission for fast cycle times, integrated diagnostics with comprehensive monitoring, and flexible encoder support for incremental and absolute feedback drives.

Kollmorgen’s AKM2G and AKMA servo motors also include an EnDat 2.2 safe feedback option, offering even higher performance and accuracy than HIPERFACE DSL for axes where functional safety is required. When combined, machine builders get a complete, integrated motion solution for safety-related applications.

SIL 3 Capability

SMM 3.0 enables complete motion systems to achieve Safety Integrity Level 3 (SIL 3) certification. While the AKD2G drive has maintained SIL 3 certification since launch, the addition of EnDat 2.2 safe feedback support now provides a complete, matched solution capable of meeting this rigorous standard. This is especially important where operators face frequent high-risk scenarios, such as stage lifting systems and heavy material handling equipment. Furthermore, the SIL 3 capability helps future-proof systems so they can scale as safety requirements evolve.
