EVS9324-ES | Lenze 3kW Compact Servo Inverter for Flexible Automation
Product Introduction
The Lenze EVS9324-ES servo inverter provides reliable speed and torque control for three-phase motors. This unit operates from a wide AC mains range of 320V to 528V at 45-65 Hz. Alternatively, you can power it from a DC supply between 460V and 740V. The drive delivers 7A output current at 8 kHz switching frequency. Furthermore, it achieves 4.8 kVA output power for U, V, W terminals. The EVS9324-ES also offers a separate 0.75 kW output for +UDC and -UDC applications. Therefore, this inverter handles a variety of industrial motion tasks including conveyors, feeders, and indexing tables.
Key Technical Specifications
These specifications show the inverter's balanced performance. For instance, the 10.5A peak current supports short-term overloads. Meanwhile, the DC output option adds flexibility for auxiliary circuits.
Mechanical Dimensions & Environmental Ratings
The Lenze EVS9324-ES features a narrow 97mm width. This slim design saves valuable cabinet space. Additionally, its 5kg weight allows easy handling during installation. However, you must apply derating in high-temperature or high-altitude environments. For example, at 50°C, reduce the output current by 20%. At 3000m altitude, reduce it by another 10%.
Installation Guidelines
First, mount the EVS9324-ES vertically on a metallic backplane. Leave at least 100mm clearance above and below for proper airflow. Next, use shielded motor cables to minimize electromagnetic interference. Keep shielded cable runs under 25 meters for best results. Additionally, connect an external mains filter if your application requires EMC compliance. Without a filter, the drive meets basic emission limits only.
For DC supply connections, observe correct polarity strictly. Exceeding 740V DC causes permanent damage. Furthermore, use a 10A fast-acting semiconductor fuse on the input line. Finally, separate control wiring from power cables by at least 200mm to avoid noise coupling.
Why Choose This Servo Inverter?
The Lenze EVS9324-ES belongs to the proven 9300 series, known for robust algorithms and field reliability. Many machine builders prefer it for retrofitting older drives. Specifically, this model works well in label applicators, small presses, and rotary tables. Besides, the wide input voltage range makes it suitable for global installations. You can also reuse existing DC bus systems from other Lenze drives. Therefore, you reduce spare parts inventory and simplify maintenance.

Frequently Asked Questions (FAQ)
1. Can the Lenze EVS9324-ES drive a synchronous servo motor?
Yes, it supports both asynchronous (ASM) and synchronous (SM) motors. Change parameter C0087 to match your motor type.
2. What is the +UDC, -UDC output used for?
This 0.75kW output supplies a DC bus voltage to another inverter. It helps create a common DC bus system for multiple drives.
3. How do I switch between 8 kHz and 16 kHz operation?
Navigate to parameter C0862 on the keypad. Higher frequency reduces audible motor noise but lowers output current to 5.2A.
4. Does the EVS9324-ES include a braking chopper?
Yes, it has an internal braking chopper. However, you must purchase an external braking resistor separately for regenerative loads.
5. Is the 2%/K derating above 40°C UL-approved?
No. For UL compliance, limit the ambient temperature to 40°C maximum without any derating. Above 40°C, the UL certification does not apply.
