EVS9328-EP - Position controller - LENZE

Lenze EVS9328-EP Brushless Controller, 9300 Series Servo Position Controller

The reference brushless controller EVS9328-EP belongs to the Lenze 9300 Servo Position Controller series. Designed for precise control of synchronous servomotors, it meets the positioning and motion requirements in industrial automation architectures. Powered by three-phase 400/480 V AC, 50/60 Hz, it delivers a rated power of approximately 22 kW (≈30 HP) and an output current of approximately 44 A, making it a suitable solution for high-inertia axes and dynamic applications. Its integrated application logic allows execution of advanced motion functions without relying exclusively on the PLC, while remaining easily integrable into CNC systems or PLC-driven lines. For maintenance and methods teams, the EVS9328-EP stands out for its control stability, trajectory repeatability and compatibility with encoder feedback—key criteria to ensure process quality on conveyors, packaging machines and handling systems.

Overview of the Lenze 9300 range

The Lenze 9300 series groups servo controllers intended for positioning and motion applications requiring controlled dynamics, trajectory accuracy and robust synchronization. Deployed across many industrial sectors, this range enables control of single or coordinated axes with parameterized motion profiles, while keeping a clear interface with the line PLC. The embedded application logic simplifies implementation of positioning functions, indexed speeds and recurring motion scenarios. I/O options, integrated safety functions in the range and optional communication modules ensure adaptation to the machine’s real needs without unnecessary complexity.

• Contrôleurs de position 9300 : focused on precise positioning, motion profile management and encoder feedback control on synchronous axes.
• Servo-contrôleurs 9300 pour axes dynamiques : dedicated to speed and torque applications with axis synchronization and controlled profile transitions.

The EVS9328-EP model belongs to the Servo Position Controller category, making it suited to stations where position accuracy, speed holding and repeatability determine production performance and final quality.

Industrial applications

The Lenze EVS9328-EP brushless controller integrates into varied environments where motion control is key to productivity and quality:

• Conveying and intralogistics : stop positioning, indexing and multi-conveyor synchronization.
• Packaging and processing : repetitive motion profiles, sustained throughputs, axis synchronization.
• Handling and Cartesian robots : translation, lifting and pick-and-place with encoder feedback for repeatability.
• Winding and unwinding : web tension management via torque and speed-controlled regulation.
• Assembly machines and auxiliary machining : auxiliary axes requiring controlled dynamics.

Integration and communication

The EVS9328-EP connects to the automation architecture via optional fieldbus modules, simplifying its integration into heterogeneous networks. Command and diagnostic communication with the PLC is carried out via process frames, while the internal application logic handles local motion sequences. This approach reduces the load on the central PLC and improves responsiveness for positioning tasks. Encoder feedback, supported by the 9300 series, ensures a robust closed loop for speed, torque and position control, essential for high throughputs and tight tolerances.

Commissioning relies on the operator panel and Lenze engineering software, with a readable parameter structure and functions dedicated to loop optimization. Maintenance teams benefit from clear diagnostics and quick access to operating states. In installations controlled by numerical control or by an upstream variable frequency drive, the 9300 brushless controller acts as a servo drive dedicated to synchronous axes, and interfaces cleanly with cell logic, machine safety and supervisory HMIs.
