E82EV222_4B Lenze 8200-Series 2.2 kW Vector Frequency Inverter

Product Overview

The E82EV222_4B (E82EV222K4B) is a versatile Vector Frequency Inverter within the proven Lenze 8200-Series, engineered for high-precision motor control in industrial environments. Delivering a rated power of 2.2 kW, this drive is optimized for 3 x 230 V mains connections, making it a specialized solution for regions or facilities utilizing lower voltage three-phase grids. Unlike basic models, the E82EV222_4B features integrated interference suppression, ensuring electromagnetic compatibility (EMC) and protecting sensitive peripheral sensors and control logic from harmonic distortion. Its advanced vector control capabilities provide superior torque at low speeds, which is essential for applications like material winding, specialized pumping, and high-torque mixers. As a phase-out model, it serves as a critical drop-in replacement for maintaining the operational life of existing 8200-Series installations without requiring costly cabinet or wiring modifications.

Technical Configuration

The E82EV222_4B architecture is defined by its modularity and high power density. The "Vector" control logic allows the drive to calculate and adjust the motor current’s magnitude and phase in real-time, providing near-servo performance from standard asynchronous motors. The integrated EMC filter (interference suppression) simplifies installation by eliminating the need for external footprint filters in most industrial environments. The unit includes a standard plug-in slot for communication modules (such as LECOM or CANopen) and a local keypad interface for rapid parameter cloning and diagnostics. Its "bookcase" design allows for space-efficient mounting, while the internal protection suite guards against overvoltage, output short-circuits, and motor thermal overload.

Technical Specifications

Technical FAQs

How does the 3 x 230 V rating affect installation compared to the standard 400 V models?

The E82EV222_4B is specifically wound for 230 V three-phase input. Ensure your motor is strapped in a "Delta" configuration (if it is a 230/400V motor) to match the drive's output voltage. Using this drive on a 400 V grid will cause immediate hardware failure.

Does this drive require an external braking resistor for high-inertia loads?

For applications involving rapid deceleration or vertical loads, an external braking resistor is highly recommended. The 8200-Series manages regenerative energy through its DC bus, and a resistor prevents "Overvoltage" trips by dissipating excess energy as heat.

What is the benefit of the "Vector" designation in this series?

"Vector" control provides much higher dynamic performance than standard V/f drives. It allows the E82EV222_4B to maintain 100% torque even at zero speed (when used with feedback) and offers better speed stability under varying load conditions.

Engineering & Installation Guide

• Cooling and Clearance: Despite its compact 14.00 cm width, the 2.2 kW power stage generates significant heat. Mount the unit vertically with at least 100 mm of free space above and below the drive. For side-by-side mounting, ensure the enclosure has active ventilation to prevent the internal heatsink from exceeding 45 Celsius.

• EMC and Grounding: While this unit includes internal suppression, high-frequency leakage currents are still present. Use a low-impedance ground strap to connect the drive's chassis to the mounting plate. All motor cables must be shielded, with the shield connected at both ends to a 360-degree EMC clamp.

• Voltage Verification: Before commissioning, verify the mains voltage. This "4B" variant is specifically for 230 V mains. Connecting this unit to a 480 V North American or 400 V European grid will result in catastrophic failure of the input bridge and DC-bus capacitors.
