The VLT 7000 Booster is a variable frequency drive, and this manual provides a detailed introduction and use of the product.
This manual covers the complete lifecycle of the VLT 7000 Booster, a frequency converter for pump and motor applications. It begins with an introduction to the product’s features such as Automatic Energy Optimization (AEO) and built‑in RF‑filter, followed by detailed safety regulations and installation guidelines.
Subsequent sections describe the electrical installation, control principle, RS‑485 communication, parameter programming, menu configuration, PID control, and service functions. The document also includes wiring diagrams, dimension data, and troubleshooting information to help users set up and maintain the device safely and efficiently. This manual is written in Chinese.
| Power grid voltage | 3 x 380‑460 V AC |
|---|---|
| Input voltage | 3 x 380‑460 V AC, 50/60 Hz |
| DC link voltage | 1.35 × grid voltage |
| Maximum motor power | up to 7.5 kW |
Before repairing, disconnect the power grid, verify it is off, wait a short time, then disconnect the motor and power plugs, and ensure proper grounding as required by regulations.
The converter first rectifies the AC grid voltage to DC, then inverts the DC to a variable‑frequency AC output for the motor.
All VLT 7000 Booster units are equipped with an RS‑485 port that uses the FC protocol for serial communication.
