2 Foreword Thank you for choosing the MV1 series compact vector control variable speed drive of Shenzhen Megmeet Drive Technology Co., Ltd. MV1 drive with a new hardware design platform that integrates V / F and no PG vector control mode, provide excellent motor driving performance, this series of drive with excellent performance, perfect functions, compact structure, convenient installation, simple debugging, easy maintenance, is the cost-effective products for drive generic and OEM markets. The relevant precautions during the installation, wiring, parameter setting and troubleshooting will be detailed in this manual. To ensure the correct installation and operation of the MV1 series drive as well as its high performance, please read carefully this user manual before installing the equipment. This manual shall be kept properly and delivered to the actual users of the drive. Safety Precautions Operation without following instructions can cause death or severe personal injury. Operation without following instructions can cause medium or slight personal injury or damage to the product and other equipment. Please install the product on the incombustible materials (e.g., metal), do not place any combustible material near the product, otherwise, fire may be caused. Do not install the product in the environment with explosive gas, otherwise, explosion may be caused. Only qualified personal can wire the drive, Never wire the drive unless the input AC supply is completely disconnected The grounding terminal of the drive must be reliably grounded, do not operate the drive with wet hands, maintaince operation can not be conducted until 1 minutes has passed after disconnecting the power supply, the bare parts of the terminal lugs in the main circuit must be wrapped with insulation tape, otherwise, electric shock may be caused. When powering up the drive that has been stored for over 2 years, the input voltage must be gradually increased with the voltage regulator, otherwise, electric shock and explosion may be caused. Only qualified personal can replace the components. Do not leave any wire or metal parts inside the drive, otherwise, fire may be caused. After changing the control board, the parameters must be properly set before operating the drive, otherwise, property damage may be caused. 2

3 Do not install the drive in the environment with water splash (e.g., near the water pipe), otherwise, you may suffer the property loss. Do not install and operate the drive if it is damaged or its components are not complete, otherwise, fire and human injury may be caused. Do not install the product in the place exposed to direct sunlight, otherwise, property damage may be caused. Do not short circuit terminal PB and terminal DC or +DC, otherwise, fire and property damage may be caused. Cable lugs must be firmly connected to the terminals of main circuit, otherwise, property damage may be caused. Do not connect AC 22V input to the control terminals other than terminal TA, TB, TC otherwise, property damage may be caused. 3
