Lenze EVS9322-ES Servo Inverter | Series 9300

Technical Specifications Breakdown

Key parameters for the EVS9322-ES are listed below for quick reference:

DC Supply Option for Backup or Special Applications

Some facilities run critical processes on DC bus systems. The EVS9322-ES supports an alternative DC supply of 460 to 740 VDC. This feature allows the drive to operate from a common DC bus or a battery-backed supply, providing continuity during AC interruptions. Engineers can design systems that switch between AC and DC sources, improving overall uptime.

Installation and Setup Guidance

Proper installation is key to reliable operation. Mount the EVS9322-ES on a flat, vertical surface to allow natural convection cooling. Ensure adequate clearance around the unit for airflow. Verify that the mains voltage and frequency match the nameplate data (320 to 528 VAC, 45 to 65 Hz). Use appropriate fusing and disconnects per local codes. For DC supply operation, confirm the DC voltage stays within 460 to 740 VDC. Follow the manufacturer's wiring diagrams for control and power terminals.

Maintenance and Reliability

Regular inspection is recommended to ensure long service life. Periodically check for dust accumulation on heatsinks and fans, as blocked airflow can cause overheating. Verify that all power connections remain tight. Monitor input voltage and current to detect anomalies early. The drive's robust design minimizes maintenance needs, but periodic checks are still essential.

Performance That Matches the Task

Motor power reaches 0.75 kW for a 4-pole asynchronous motor at both 400V and 480V. Output current is rated at 2.5 A (8 kHz) and 1.8 A (16 kHz) for both voltages, while maximum output current reaches 3.8 A (8 kHz) and 2.7 A (16 kHz) at 480V. These figures indicate the drive can handle dynamic loads without derating. The output power of 1.7 kVA (400V) and 2.1 kVA (480V) provides ample headroom for typical servo applications.

Servo Inverter Built for Precision and Flexibility

Industrial motion control demands drives that respond instantly, hold torque accurately, and survive harsh electrical environments. The Lenze EVS9322-ES from the Series 9300 delivers exactly that. This servo inverter is engineered for applications where precise speed and position control are non-negotiable. With a wide input voltage range and flexible supply options, it simplifies machine design across multiple regions and power architectures.

Why the Wide Input Range Matters

The EVS9322-ES accepts a mains voltage from 320 to 528 VAC, covering both 400V and 480V nominal systems. This flexibility means one drive model can be stocked for multiple regions, reducing inventory complexity. The 3-phase input, combined with a frequency range of 45 to 65 Hz, makes it adaptable to regional power standards. The 45 to 65 Hz range ensures stable operation even where grid frequency fluctuates.

Compact and Lightweight Design

The inverter weighs only 3.5 kg, making it easy to mount in control cabinets or on machinery. Its compact footprint saves valuable panel space. The lightweight construction does not compromise robustness, as the unit is built for industrial environments.

Compatibility and Integration

The Series 9300 platform is designed for seamless integration into existing automation systems. The EVS9322-ES works with standard 3-phase mains supplies and can be integrated into DC bus systems. Its flexible I/O and communication options (if available) should be configured per the user manual. Always consult the official documentation for specific wiring and parameter settings.
