Lenze E82EV222K4C Frequency Inverter 2.2kW

E82EV222K4C | Lenze 8200 Vector Drive 2.2kW

Product Introduction

The Lenze E82EV222K4C belongs to the 8200 Series of frequency inverters. It functions as a base controller for three-phase motors. With a rated motor power of 2.2 kW, this drive suits many light to medium industrial applications.

This inverter supports vector control as a standard feature. Vector control gives you excellent torque regulation even at low speeds. Therefore, your machinery runs smoothly under varying loads.

Furthermore, the E82EV222K4C accepts a wide AC input range from 320V to 550V. The rated mains voltage is 400V AC. Alternatively, you can supply it with 450–775V DC, which adds flexibility for DC bus systems.

Its compact design saves panel space. The IP20 protection class means you should install it inside a clean control cabinet.

Built-in Brake Chopper Data

The E82EV222K4C includes an integrated brake chopper. This feature allows you to connect an external braking resistor. Regenerative energy from the motor gets dissipated as heat.

Minimum brake resistance: 230 Ω
Make sure your resistor meets or exceeds this value. A lower resistance could damage the chopper circuit.

Additionally, you can adjust the switching threshold of the chopper. Refer to the Lenze manual for parameter settings. Proper configuration prevents DC bus overvoltage faults.

Environmental and Derating Information

Ambient operating temperature: –10°C to +55°C
Ambient storage temperature: –25°C to +60°C

Current and power derating apply under extreme conditions. For every degree above 40°C, reduce the output current by 2.5%. For altitudes above 1000 meters, derate by 5% per additional 1000 meters.

Meanwhile, keep adequate spacing around the E82EV222K4C for airflow. Although it is efficient, the 100 W power loss still generates heat. A cooling fan inside the cabinet helps maintain reliability.

Installation Guidelines

First, disconnect all power before installing the E82EV222K4C. Check that your mains voltage falls inside the 320–550V AC range. For DC feeding, use 450–775V DC only.

Next, select proper fusing. A 10 A fuse or B10 A circuit breaker typically works for this drive. Use cable cross-sections suitable for 3.9 A continuous current.

Then, mount the inverter vertically on a flat metal plate. The IP20 enclosure does not protect against dust or moisture. Therefore, place it inside a control cabinet with adequate ventilation.

After wiring, configure the vector control parameters. Enter your motor nameplate data for optimal performance. Finally, run a low-speed test before putting the drive into full production.

Frequently Asked Questions (FAQ)

1. Can the E82EV222K4C run a 1.5 kW motor?
Yes, you can use it with smaller motors. However, the drive's rated power is 2.2 kW. Adjust the motor parameters accordingly to avoid overcurrent protection trips.

2. What is the difference between E82EV152K4C and E82EV222K4C?
The main difference is motor power. The E82EV152K4C is rated for 1.5 kW, while the E82EV222K4C handles 2.2 kW. Both share the same voltage range and vector control features.

3. Do I need a separate braking resistor for this inverter?
Only if your application requires frequent stopping or has high inertia loads. The built-in chopper supports an external resistor. For simple ramps, the internal DC bus capacitor may be sufficient.

4. How do I adjust the switching frequency on the Lenze 8200 drive?
You can change it via a software parameter. The rated output current of 3.9 A is specified at 8 kHz. Higher switching frequencies reduce audible noise but increase power loss.

5. What should I do if the drive trips on overvoltage?
First, check the mains voltage. It should not exceed 550V AC. Next, verify your braking resistor connection and resistance value. For DC supply, ensure voltage stays below 775V. Also lengthen the deceleration time if possible.
