ME320L(N) is a new generation of elevator specialized vector control inverter, suitable for driving control of permanent-magnet synchronous motor and asynchronous motor, with various rotary encoder interfaces. Its main features include self-tuning function of motor parameters, quick startup of curve processing, multi-stage S curve settings, and 4-stage acceleration and deceleration time settings to ensure comfort during elevator operation. It also has a simple and practical battery running function, as well as elevator special functions such as inspection, brake contactor control, output contactor control, forced deceleration judgment, over speed testing, speed deviation testing, advanced door open, contact conglutination testing, motor overheat testing, startup pre-torque compensation, making elevator control easier.
The ME320L(N) is a specialized inverter designed for elevator applications, capable of controlling permanent‑magnet synchronous and asynchronous motors. It offers features such as self‑tuning, multi‑stage S‑curve acceleration, battery‑run mode with a 48 V input, and built‑in DC reactor and braking unit for improved power factor.
The manual covers safety information, mechanical and electrical installation, wiring procedures, operation and test‑run steps, detailed function parameter tables, application adjustments, and fault diagnosis with remedies. It also includes guidance on parameter copying for batch adjustments and RJ45‑based panel placement.
| Supported motor types | Permanent‑magnet synchronous motor and asynchronous motor |
|---|---|
| Battery input voltage | 48 V |
| Built‑in components | DC reactor and braking unit |
| Communication interface | RJ45 terminal |
| Parameter copy feature | Parameter copy unit for batch adjustment |
It can control both permanent‑magnet synchronous motors and asynchronous motors.
The inverter requires a 48 V power supply for its battery‑run mode.
Confirm that the mains voltage matches the inverter, verify correct wiring of input and output terminals, and ensure no short circuits before power‑on.
