This drive is equipped with safety features such as Safe Torque Off (STO), meeting the SIL3/PL e safety level requirements. It supports Sercos III and EtherCAT real-time industrial Ethernet communication, enabling multi-axis synchronous motion control.

Core function
Three-loop closed-loop control
Supports three-loop control of position, speed, and torque, achieving high-precision transmission positioning, suitable for applications with extremely high requirements for dynamic response and positioning accuracy.
Hiperface multi-loop absolute encoder interface
HS45 feedback code corresponds to multi-loop absolute encoders, with high resolution. After power loss, it does not need to return to the origin, and can be directly operated upon startup, significantly improving equipment efficiency.
Safe Torque Off (STO) safety function
Built-in SIL3-level safety torque shutdown function, compliant with IEC 61508/ISO 13849 functional safety standards, meeting the requirements of high safety levels.
Real-time industrial Ethernet communication
Supports Sercos III and EtherCAT communication protocols, achieving multi-axis high-speed synchronous control, with cycle times reaching sub-millisecond level.
Flexible start-up and stop
Unique soft start and soft stop functions, reducing mechanical shock and prolonging the lifespan of transmission components, particularly suitable for precision machinery and vulnerable load scenarios.
Auto-Tuning automatic tuning
Supports automatic identification of motor parameters, simplifying the debugging process and shortening the project delivery cycle.
Strong overload capacity
Short-term 300% overload capacity, capable of handling impact loads and sudden working conditions.
Online diagnosis and maintenance
Built-in microprocessor, with self-testing, link status monitoring, and fault diagnosis functions, supporting online module replacement during operation.
