This document is a quick guide for the VLT Micro FC 51 frequency converter. It provides information on the safety and safety precautions of the converter, as well as information related to voltage, leakage current, and motor thermal protection. It also provides basic information on the installation and operation of the frequency converter.
The guide begins with safety information, including high‑voltage warnings, required grounding, leak‑current limits and the mandatory waiting times before servicing. It then covers mechanical dimensions, mounting clearances, electrical installation, wiring of the main power and motor, and the layout of control terminals.
Subsequent sections describe basic LCP programming, menu navigation, parameter groups, and essential operating parameters such as input voltage ranges, output current limits, efficiency, and protection functions. The document also lists optional accessories and environmental limits for the VLT Micro FC 51 drive. This manual is written in Chinese.
| Input voltage (single) | 200‑240 V AC |
|---|---|
| Continuous output current (max) | 9.6 A |
| Efficiency (best case) | up to 95.6 % |
| Enclosure weight | 1.1 kg – 3.0 kg (depending on frame size) |
| Maximum cable size (power & motor) | 4 mm² / 10 AWG |
Wait 4 minutes for M1, M2 and M3 units, or 15 minutes for M4 and M5 units before touching any live parts.
Only a B‑type (time‑delayed) residual‑current device (RCD) may be used on the supply side of the drive.
The drive is rated for a maximum ambient temperature of 40 °C.
