: Indicates that the incoming main AC voltage drops below the functional threshold. Verify the stability of your incoming main power supply line.
The is a reliable micro variable frequency drive (VFD) widely used in industrial automation to control the speed and torque of three-phase AC induction motors . If you are dealing with a "repack" unit—either a refurbished, surplus, or repackaged drive—having a clear understanding of its operation manual is essential to ensure a safe installation and avoid costly mechanical damage.
Includes terminals for analog input, digital input ( ), and relay outputs. 2. Operation Command Modes (Parameter F0.02)
The manual mandates that only trained personnel should install the drive. Key considerations include: convo inverter cvfs1 manual repack
The series (often branded under SHENZHEN CONVO or KANGWO ) is a compact, high-performance mini frequency inverter designed for simple industrial automation. Because these units are often used in demanding environments, "repacking"—a term typically referring to a complete teardown, cleaning, and thermal refresh—is essential for extending the life of the internal DC bus capacitors and power modules.

The CVFS1 is operated via the integrated keypad. The "repack" manual will highlight the following parameters for quick setup: Description Control Mode 0: SVC, 1: V/f Control F0.02 Command Source 0: Keypad, 1: Terminals, 2: Comm F0.03 Speed Reference 0: Keypad, 1: AI1 (0-10V), 2: AI2 (4-20mA) F0.11 Acceleration Time Set time to reach max frequency F0.12 Deceleration Time Set time to stop from max frequency F0.15 Maximum Frequency Default is usually 50.00Hz or 60.00Hz F3.00 Motor Rated Power Set according to motor nameplate F3.01 Motor Rated Voltage Set according to motor nameplate F3.02 Motor Rated Current Set according to motor nameplate : Indicates that the incoming main AC voltage
