Lenze EVS9327‑ETV004 – High-Performance Servo Controller with Safe Torque Off Functionality
The Lenze EVS9327‑ETV004 is a robust and intelligent servo controller designed as part of the 9300-Series, optimized for high-performance motion control applications in industrial environments. Delivering a nominal power of 15 kW and a peak power of 18.5 kW, this drive supports 3-phase 400–480 VAC input voltage and is engineered to ensure precision, reliability, and safety in servo motion systems.
What sets this model apart is the inclusion of the “V004” variant, which confirms the presence of Safe Torque Off (STO) functionality. This safety feature is crucial in modern industrial automation, as it ensures that the drive can safely and effectively disable torque output to the motor in emergency or protective shutdown scenarios. STO eliminates the need for contactors in the power supply line, simplifying design and increasing system integrity while adhering to international safety standards.
The EVS9327‑ETV004 features vector-controlled servo operation, enabling precise closed-loop control of speed, position, and torque. This advanced control is facilitated by compatibility with a range of motor feedback devices, including resolvers, TTL encoders, and sin/cos encoders, supporting both single-turn and multi-turn configurations. These feedback options enable excellent synchronization and accurate motion profiles in demanding applications such as robotics, printing, packaging, and material handling.
Built-in PTC motor monitoring provides an additional layer of protection by monitoring motor temperature through thermistors. This safeguards against overheating and supports longer motor life and consistent performance under high loads or extended operation periods.
The controller is designed for panel-mount installation and is suitable for integration into electrical control cabinets. With an IP20 protection rating, it is intended for environments that are clean, dry, and temperature-regulated. The supported operational temperature range ensures dependable performance in a variety of industrial conditions.
The Lenze 9300 Series is known for its modularity and advanced software capabilities, and the EVS9327‑ETV004 upholds this legacy by offering flexible programming and motion control customization. It is fully compatible with engineering tools for commissioning, parameter setting, diagnostics, and firmware updates, allowing for reduced setup time and easier maintenance.
In compliance with EC Low Voltage and EMC directives, this servo drive is designed for global use in industrial settings. Comprehensive manuals, wiring diagrams, and commissioning documentation further support smooth integration into automated systems.
Overall, the Lenze EVS9327‑ETV004 is a feature-rich, reliable, and safety-enhanced servo drive ideal for mid- to high-power applications requiring precision control, built-in safety mechanisms, and seamless integration into complex motion architectures.
