Convo Inverter Cvfs1 Manual Link [better] -

Here’s a good, detailed article that discusses the Convo CVFS1 drive and includes references to the manual, along with a direct link to the manual itself.

Article / Resource: "Understanding the Convo CVFS1 Series: A Practical Guide" Source: Practical Machinist / Electrician's Forum (compiled from user manuals and application notes) The Convo CVFS1 is a popular, budget-friendly Voltage/Frequency (V/F) control AC drive (inverter) commonly used for controlling 3-phase motors from single-phase input (up to certain HP ratings). While the interface is straightforward, first-time users often struggle with the parameter mapping and terminal wiring . Key points from the CVFS1 manual:

Model Number Breakdown (e.g., CVFS1-2S-0015G):

2S = 220V Single/Three-phase input 0015G = 1.5 kW (2 HP) convo inverter cvfs1 manual link

Default Parameter Access :

The drive defaults to a simple user mode (showing only F0.xx parameters). To access all parameters (including advanced motor tuning), you must set F0.00 = 0 (or 1 for all parameters, depending on revision).

Common Wiring Mistake :

For run/stop using external switch: Terminals FOR (forward run) and DCM (digital common) need a dry contact. Do NOT apply voltage to these terminals.

Analog Speed Control :

Use terminal VRF (0–10V input) and ACM (analog common). Set F0.03 = 0 (external analog) and F0.04 = 1 (terminal control mode). Here’s a good, detailed article that discusses the

Fault Codes :

E.OC1 (Overcurrent during acceleration) – increase acceleration time F0.15. E.LU (Low voltage) – check AC supply or DC bus capacitor aging.
