Method to Verify Suitability of Lenze E82EV751K4C for Your Application

Основная предпосылка: This obsolete 8200 Vector 0.75kW sensorless vector inverter is only suitable for spare part replacement on legacy machines; not recommended for new project procurement.

Verification covers four aspects: load power & крутящий момент, process control requirements, относящийся к окружающей среде & installation conditions, project type (new retrofit / maintenance spare).

1. Власть & Согласование нагрузки (Primary Check)

✅ Acceptable Conditions

1. Rated power of driven motor: 3-phase 0.75kW, 380V asynchronous motor; motor rated current ≤1.9A (inverter rated output current)
2. Short-time overload requirement: Макс. 180% overload for up to 60 секунды. Suitable for applications with mild start-stop shock and short peak load.
3. Compatible load types:

✅ Рекомендуется: Light constant-torque loads (conveyor rollers, traction rollers, small mixers), переменные крутящие нагрузки (маленькие фанаты, маленькие насосы)

✅ Inertial loads: Paper rolls, конвейерные ленты, fast stop with external brake resistor (onboard brake transistor)

❌ Не подходит

Мощность двигателя >0.75кВт; continuous heavy load, frequent heavy impact loads (дробилки, stamping mechanisms)

3. Коммуникация: Expandable PROFIBUS / CAN bus modules for PLC connection; basic DI/DO analog terminal control
4. Старт-стоп: S-curve acceleration/deceleration to reduce mechanical shock, ideal for conveying and packaging auxiliary equipment

❌ Unsuitable Applications

1. Applications requiring encoder closed loop, high precision positioning, multi-axis electronic cam, синхронное управление (functions of servo or high-end vector drives, 8200 Vector does not support encoder interface)
2. High-precision tension unwinding/rewinding, main drive of high-speed precision printing machines
3. Operating conditions requiring fast dynamic response and frequent acceleration/deceleration under heavy load
