Overview of the Lenze 9300 range

The 9300 series from Lenze groups servo-drives designed for axis drives in self-contained machine subassemblies. It covers a wide power range, approximately 0.37 to 75 kW, which simplifies standardization of a drive fleet on a single technology platform. The brushless controllers in this range favor a modular architecture, allowing adaptation of application functions and scalability of performance according to process requirements. The control strategy ensures precise speed and torque regulation, with the option to integrate position feedback if required by the application.

• Drive modularity : selection of power ratings and options to match desired loads and dynamics, from material handling to continuous processes.
• Dedicated servo control : control of synchronous or asynchronous motors with precise handling and stable regulation across the speed range.
• Machine integration : easy insertion into existing automation architectures via modules and I/O designed for PLC control.
• Facilitated maintenance : design focused on quick substitution and reproducible parameterization, useful for corrective and preventive maintenance.
• Operational continuity : range compatibility across many frames and versions to secure sourcing and replacements.

The EVS9330-ES fits this standardization approach, particularly suited to industrial environments where line availability and process stability are critical. Its 45 kW sizing is suitable for main drives or high-torque axes, while remaining compatible with standard electrical cabinet integration.

Industrial applications

This brushless controller integrates into a wide spectrum of applications where speed and torque regulation must remain stable despite load variations. Typical use cases include material handling and conveying, processing and packaging, as well as automated assembly systems. In continuous processes, it helps maintain quality through setpoint consistency. In modular machines, it enables reproducible commissioning, useful for identical replacements and retrofit operations.

• Conveying and intralogistics : control of translation axes and motorized rollers with controlled ramps.
• Packaging : axis synchronization, speed dosing, maintaining web tension according to machine architecture.
• Assembly and handling : axis servocontrol for pick-and-place, indexing, cadence modulation via the controller.
• Textile and paperboard : drive of rewinders and unwinders with stable torque setpoint.
• Peripheral robotics : control of auxiliary axes interacting with a motion control system.

Integration and communication

The EVS9330-ES is designed to integrate into automation architectures controlled by a programmable logic controller. Communication is handled via optional cards adapted to common industrial fieldbus systems. This modular approach allows connecting the inverter to the existing control network, exchanging statuses and setpoints, and centralizing diagnostics. Commissioning is carried out using a local control panel and the manufacturer's dedicated software tools, with structured parameters simplifying the reproduction of configurations during a standard exchange or repair. Power and control wiring follow common cabinet practices, with dedicated terminal blocks and adherence to EMC rules for signal reliability.

In operation, the servo vector control strategy ensures stable response to load variations. Safety, braking and controlled stop functions depend on options and the overall architecture. Positioning, when required, relies on compatible sensor feedback according to configuration. This flexibility allows aligning the inverter's functional level with process requirements without multiplying references.
