When the CVF-S1 encounters an operational anomaly, it stops outputting voltage and displays a distinct fault code on the LED display. Fault Code Fault Description Likely Cause Overvoltage during deceleration Deceleration time is too short for the load inertia. Increase b-10 or install a braking resistor. E.OC Overcurrent during acceleration Acceleration time is too fast or motor is jammed. Increase b-09 and inspect the mechanical load. E.LU Undervoltage Low mains input voltage or faulty contactor. Check input power line stability and voltage levels. E.OH Inverter Overheating Cooling fan blocked or ambient temperature too high. Clean dust from the heatsink; replace the cooling fan. E.OL Motor Overload Drive or motor running beyond rated current limit. Reduce load mechanical resistance or upgrade VFD capacity. Maintenance and Care

The manual’s troubleshooting section maps codes (e.g., E01 — Overload, E03 — Battery Short) to likely causes and corrective steps, often with a decision tree.
This chapter explains how to use the CVF-S1's built-in keypad. You'll learn about each button, symbol, and how to navigate the menu system. Your specific (e
This technical guide serves as a comprehensive reference piece mapping out the exact operational parameters, safety wiring protocols, and programming steps typically detailed in the official PDF document. Key Technical Specifications
Before modifying any parameter, review factory defaults. To reset CVF-S1 parameters to factory defaults: Set l-52 = 1 and l-53 = 0 . Check input power line stability and voltage levels
For a complete list of all error codes and their detailed solutions, always refer to Chapter 9 of the official manual.
