Lenze E84AVSCE7524VX0 VFD Drive

E84AVSCE7524VX0 Lenze 8400 Series Drive

Product Introduction

The E84AVSCE7524VX0 from Lenze belongs to the Series 8400 product line. This variable frequency drive delivers stable performance even under tough conditions. It accepts input voltages from 400V to 500V AC. As a result, it works with many industrial power systems.

This drive controls AC motors with high efficiency. For example, its power loss reaches only 320 W at rated output current. Therefore, it saves energy during long operations. The E84AVSCE7524VX0 also includes forced air cooling with active temperature monitoring. This feature prevents overheating and extends the drive’s lifespan.

Key Technical Specifications

The input current changes with the operating temperature. Up to +45 °C, the drive draws 20.0 A at 400V and 16.0 A at 500V. Meanwhile, up to +55 °C, it draws 15.0 A at 400V and 12.0 A at 500V.

Output current also follows a similar pattern. At +45 °C, it provides 16.5 A at 400V and 13.2 A at 500V. At +55 °C, the output adjusts to 12.4 A at 400V and 9.9 A at 500V. Both values are key for thermal planning.

The switching frequency is fully adjustable. Users can choose 2, 4, 8, or 16 kHz. This flexibility helps balance motor noise and efficiency.

Supported control modes include V/f control, SLVC (Sensorless Vector Control), SLPSM, and servo control.

Additionally, the E84AVSCE7524VX0 meets EMC standard EN 61800-3. It can achieve C2 or C1 compliance with proper filtering. The maximum shielded motor cable length is 50 meters.

Mechanical and Environmental Data

This drive carries an IP20 protection rating. Consequently, it suits indoor installations where dust and debris are minimal. The maximum operating temperature reaches 55 °C.

Cooling relies on forced air with built-in temperature monitoring. Therefore, the drive automatically reduces output current if internal temperatures rise too high. This thermal management ensures reliable operation without sudden shutdowns.

Installation Guidelines

First, mount the E84AVSCE7524VX0 vertically inside a control cabinet. Ensure enough free space around the unit for airflow. Specifically, maintain at least 100 mm clearance above and below the drive.

Next, use shielded motor cables up to 50 meters long. Shorter cables improve EMC performance. For input power, match the voltage between 400V and 500V AC. Check local wiring regulations before installation.

Furthermore, install an external circuit breaker for overcurrent protection. Do not connect power factor correction capacitors to the output side. This action may damage the drive.

Finally, set the switching frequency based on your application. Use 2 or 4 kHz for high torque at low speeds. Use 8 or 16 kHz for quieter motor operation but higher EMI.

Frequently Asked Questions

1. Can the E84AVSCE7524VX0 run a permanent magnet motor?
Yes. The SLPSM control mode directly supports permanent magnet synchronous motors.

2. Do I need an external EMC filter for CE compliance?
For C2 or C1 environment compliance, add an external EMC filter. The drive alone meets C3 default levels.

3. What happens if the drive runs above 55 °C?
It will reduce output current automatically. If temperature continues rising, the drive shuts down to prevent damage.

4. How do I change the switching frequency on this model?
Use parameter C00012. Options are 2, 4, 8, or 16 kHz. Save the setting and reset the drive.

5. Is the E84AVSCE7524VX0 compatible with Lenze’s software tools?
Absolutely. Use Lenze Engineer or Global Drive Control for parameter setup and diagnostics.
