Convo Inverter Cvf-s1 Manual -

The standard CVF-S1 keypad is the primary interface for programming. It generally consists of:

: Never touch inverter terminals while power is on; high voltage persists even after power-off until the internal capacitors discharge. Power Disconnection

: Designed for single-phase 220V input, providing a three-phase output for standard induction motors.

The Convo CVF-S1 is a reliable, compact variable frequency drive (VFD) used to control the speed and torque of AC induction motors. Whether you are setting up a new unit, troubleshooting an error, or optimizing performance, having a clear understanding of the manual is essential.

The digital operator panel allows you to modify parameters, monitor runtime statistics, and control the motor locally. Keypad Buttons Enter or exit the programming menu. Convo Inverter Cvf-s1 Manual

The manual contains hundreds of parameters, but you only need a few core groups to get the motor running.

Modbus RTU communication via RS485 protocol. Installation and Wiring Guidelines

Maintain a minimum 100mm vertical clearance at both the top and bottom of the unit to support built-in fan exhausting.

The Convo Inverter CVF-S1 consists of several key components, including: The standard CVF-S1 keypad is the primary interface

When a fault occurs, the CVF-S1 stops the motor and displays an error code on the LED screen. Refer to this quick-reference matrix to diagnose the issue: Fault Code Fault Description Potential Causes Overcurrent during acceleration/deceleration Acceleration time too short; Motor load is too heavy. Increase b-07 / b-08 values; Check motor size. E.OU1 / E.OU2 Overvoltage during deceleration/steady run Deceleration time too short; Surge in input voltage. Increase deceleration time; Install a braking resistor. E.LU Undervoltage

The CVF-S1 drive targets low-power environments where compact physical footprints and single-phase incoming power are standard. Single-phase AC 200V–240V, 50Hz / 60Hz. Output Power Range: Typically spans from 0.4 kW to 2.2 kW .

Periodically check terminals for tightness.

| Error Code | Error Type | Probable Cause | Recommended Action(s) | | :--- | :--- | :--- | :--- | | | Over-current during Acceleration | Acceleration time too short; Torque boost too high. | 1. Extend L-1 (Accel Time). 2. Lower torque boost voltage. | | Er.02 | Over-current during Deceleration | Deceleration time too short. | Increase the deceleration time parameter ( L-2 ). | | Er.05 | Over-voltage during Deceleration | Deceleration time too short; Power supply anomaly. | 1. Extend L-2 (Decel Time). 2. Check incoming power. 3. Install brake resistor. | | Er.09 | Inverter Overload | Load on motor is too heavy; Acceleration time too short. | 1. Reduce the mechanical load. 2. Increase L-1 (Accel Time). | | Er.11 | Inverter Over-temperature | Airflow blocked; Ambient temperature too high; Fan broken. | 1. Clean cooling fan and vents. 2. Lower carrier frequency. 3. Replace fan. | | Er.14 | Output Phase Loss | Loose or broken connection between inverter and motor. | Disconnect power and check the integrity of all motor wiring connections. | | Er.15 | IPM Fault | Output short circuit or ground fault; Power module damaged. | 1. Check all output wiring. 2. If no external problem exists, contact manufacturer. | The Convo CVF-S1 is a reliable, compact variable

. Inside lay the sleek inverter, its green and red buttons waiting like a silent promise. Arthur carefully wired the device, following a guide similar to the Delta VFD-S User Manual he had once used for a different project. He set the parameter , opting for panel control so he could command the machine with a single touch.

Disclaimer: This guide is a summary. Always consult the official Convo Inverter CVF-S1 Instruction Manual for precise technical specifications and safety instructions.

The CVF-S1 offers three levels of parameters: Basic (b-), Intermediate (L-), and Advanced (H-). Basic parameters are for simple setup, while advanced parameters unlock complex features. To access all three levels, you must enable "Advanced Parameter Mode" ( b-0 = 2 ).
