Lenze EVS9325-ES Servo Controller 13A 400V

EVS9325-ES | Lenze 5.5kW Servo Drive for Precision Motion

Product Introduction

The Lenze EVS9325-ES servo controller provides exceptional speed and torque regulation. This unit operates from a 3 AC 400V or 480V mains supply at 50/60 Hz. Furthermore, it accepts an alternative DC supply from 460V to 740V DC. You get 13A output current at 8 kHz switching frequency, or 9.7A at 16 kHz. The maximum output current reaches 19.5A at 8 kHz, handling peak loads easily. Additionally, this servo controller drives a 5.5 kW four-pole asynchronous motor. Therefore, it suits robotics, packaging machines, and positioning systems.

Key Technical Specifications

These figures demonstrate the drive’s flexibility. For instance, the wide DC input range allows battery or common DC bus operation. Meanwhile, the 19.5A peak current helps accelerate high-inertia loads.

Mechanical Dimensions & Environmental Ratings

The Lenze EVS9325-ES has a slim 135mm width, saving cabinet space. Its 7.5kg weight allows single-person mounting. However, you must derate the output when operating above 40°C or 1000 meters altitude. For example, at 50°C ambient, reduce the current by 20%. Similarly, at 3000m altitude, reduce by another 10%.

Installation Guidelines

First, mount the EVS9325-ES vertically on a flat, conductive backplate. Ensure 100mm free space above and below for cooling airflow. Next, use shielded motor cables to reduce EMI. Keep cable lengths under 25 meters for optimal EMC performance. Additionally, connect the mains filter exactly as shown in the manual. Without a filter, mains current rises to 16.8A, so size your protection accordingly.

For the DC supply option, observe correct polarity. Overvoltage beyond 740V DC damages the unit. Furthermore, use a fast-acting semiconductor fuse rated for 20A. Finally, connect all control wires with twisted pairs and separate them from power cables by at least 200mm.

Why Choose This Servo Controller?

This drive belongs to Lenze’s 9300 servo series, known for high dynamic response. Many system integrators prefer it for cam profiling and electronic gearing. Specifically, the EVS9325-ES excels in labelers, cut-to-length lines, and winding machines. Besides, its dual AC/DC input capability simplifies retrofit projects. You can reuse existing DC bus systems from other machines. Therefore, you save both cost and engineering time.

Frequently Asked Questions (FAQ)

1. Can the Lenze EVS9325-ES run a synchronous servo motor?
Yes, it supports both asynchronous (ASM) and synchronous (SM) motors. You must set the correct motor parameter in the software.

2. What happens if I supply 800V DC to the alternative DC input?
The unit will fail immediately. The maximum allowed is 740V DC +0% with no tolerance. Use a proper DC power supply.

3. Do I need an external braking resistor?
No, the EVS9325-ES has an internal braking chopper. However, for high-inertia or frequent stops, add an external resistor to absorb regenerative energy.

4. How do I change the switching frequency from 8 kHz to 16 kHz?
Navigate to parameter C0862 in the keypad. Higher frequency reduces motor noise but lowers output current to 9.7A.

5. Is this drive UL approved for 55°C operation?
No. The 2%/K derating above 40°C is not UL-approved. For UL compliance, limit ambient to 40°C without derating.
