Lenze E82EV751_2B 8200 Series Variable Frequency Drive

Providing precise speed and torque regulation for industrial three-phase AC induction motors, the Lenze E82EV751_2B serves as a reliable vector-controlled variable frequency drive within the legacy 8200 Vector series. This compact drive module is engineered for space-saving control cabinet installation, delivering robust performance in demanding automation architectures. It supports both single-phase and three-phase mains connections, making it highly adaptable to various field power configurations.

Key Features

• Flexible Input Configuration: Supports 1-phase or 3-phase AC 230/240 V input voltages.
• High-Frequency Output: Delivers an adjustable output frequency from 0 to 650 Hz, ideal for high-speed spindle operations.
• Modular Communication: Equipped with an integrated slot for pluggable fieldbus modules (CAN, PROFIBUS, or LECOM).
• Robust Protection: Built-in motor overload, short-circuit, earth-fault, and overvoltage monitoring circuits.
• Compact Form Factor: Optimized footprint designed for space-restricted control panels.

Applications

• Conveyor and material handling systems requiring controlled acceleration and deceleration.
• Industrial pumps, fans, and ventilation systems.
• Packaging machinery and automated assembly lines.
• Machine tool auxiliary drives and high-speed spindle applications.

Alternative Models & Compatibility

The E82EV751_2B is often designated in PLM systems under the code E82EV751K2B. It is fully compatible with the Lenze EMZ8201BB parameterization keypad and the EMF2102IB LECOM-A (RS232/RS485) communication module. When replacing an older 8200 Standard series drive, note that the 8200 Vector series uses a different parameter structure, requiring a manual transfer of settings rather than a direct copy-paste via older software versions.

Application Pitfalls & Engineering Notes

As a legacy phase-out model, thermal management is critical to preserving the unit's internal DC-bus capacitors. Ensure a minimum vertical mounting clearance of 100 mm above and below the drive. Continuous operation at the maximum 4.0 A output current in ambient temperatures exceeding 40 degC will accelerate capacitor degradation; external cabinet cooling or derating is highly recommended in these environments.

Commissioning & Wiring Tips

Always use low-capacitance, shielded motor cables to minimize high-frequency leakage currents. The cable shield must be grounded over a large surface area directly to the conductive mounting plate using grounding clamps. To prevent electromagnetic interference, never route control cables parallel to motor power cables; maintain a minimum physical separation of 10 cm.
