Convo Inverter Cvf G3 Manual May 2026
For industrial automation, the CVF G3 supports Modbus RTU via the RJ45 port (or terminal block, depending on revision). The manual provides a complete register map.
Basic Communication Setup (Per Manual):
| Parameter | Setting | Meaning | | :--- | :--- | :--- | | FA.00 | 1 to 247 | Slave address (unique for each inverter on network) | | FA.01 | 3 | Baud rate: 9600 bps (most common) | | FA.02 | 1 | 8-N-1 data format (8 data, no parity, 1 stop) |
Common Holding Registers (Addresses):
If your PC or PLC cannot communicate, the manual advises checking FA.03 (response delay) and ensuring termination resistors (120 ohms) are installed on long networks.
Main Circuit Terminals:
Control Terminals (Low voltage): | Terminal | Function | Description | |----------|----------|-------------| | +10V | 10V reference | Max 20mA | | AI1 | Analog input 1 | 0-10V or 0-20mA (via jumper) | | AI2 | Analog input 2 | 0-10V only | | GND | Analog common | | | D1-D4 | Digital inputs | Dry contact, active low | | COM | Digital common | | | DO1 | Open collector output | Max 50mA/30V | | RA-RB-RC | Relay output | 250VAC/2A (NO/NC) | | RS485 A/B | Modbus RTU | |

The Convo CVF-G3 is a high-performance variable frequency drive (VFD) designed for general industrial applications, offering precise control over motor speed and torque. This guide synthesizes critical technical details from official CONVO Inverter Manuals and expert sources to help you install, program, and maintain your unit. Core Specifications and Series Models
The CVF-G3 series covers a broad power range, typically ranging from small 0.4kW units to larger industrial models. Input Voltage Options: Convo Inverter Cvf G3 Manual
Single Phase: 220V-240V (Models like 0.4G1-220V to 3.0G1-220V).
Three Phase: 370V-440V (Models like 0.4G3-380V up to 7.5G3-380V and higher).
Applications: Ideal for fans, pumps, conveyors, compressors, and injection molding machinery. Installation and Wiring Guide
Proper installation is vital for safety and equipment longevity. Ensure the installation site is clean, well-ventilated, and free from corrosive gases. Main Power Wiring: Connect the AC power supply to terminals R, S, and T.
Connect the motor to output terminals U, V, and W. Ensure the wire length does not exceed 50 meters to minimize current leakage. Control Terminals:
S1 - S5: Multi-function digital inputs (factory default for Forward/Reverse and multistage speed).
AVI (0-10V) & ACI (4-20mA): Analog inputs for external frequency setting. RA, RB, RC: Relay output terminals for status signaling.
Braking: If your application requires rapid stopping, connect a braking resistor to terminals P and B. Programming and Key Parameters
The CVF-G3 uses a parameter-based configuration system. Access these through the digital operator panel.

Convo Inverter Cvf G3 Manual For industrial automation, the CVF G3 supports Modbus
It was a typical Monday morning for John, a maintenance technician at a large industrial plant. He had just received a call from his supervisor, Mike, to investigate an issue with one of the plant's critical systems - the Convo Inverter Cvf G3.
As John arrived at the site, he noticed that the system's display screen was flashing error codes and the machine was making a strange humming noise. He quickly grabbed his trusty multimeter and began to scan the system's electrical connections.
After a few minutes of testing, John realized that the problem lay with a faulty capacitor in the inverter's control circuitry. He made a note of the part number and headed to the storage room to retrieve a replacement.
As he was searching for the part, John stumbled upon an old manual for the Convo Inverter Cvf G3. He hadn't seen one in years, and his curiosity got the better of him. He sat down on a nearby crate and began to flip through the pages.
The manual was a thick binder filled with detailed diagrams, technical specifications, and troubleshooting guides. John was impressed by the level of detail and the clear instructions provided.
As he read through the manual, John discovered that the capacitor he needed was listed under the "replaceable parts" section. He quickly found the correct part and headed back to the site.
With the new capacitor in hand, John was able to repair the Convo Inverter Cvf G3 in no time. He tested the system, and to his relief, it was functioning normally.
Mike, his supervisor, arrived just as John was finishing up. "How's it going?" Mike asked. John replied, "All fixed! I found the problem and replaced the faulty capacitor."
Mike nodded in approval. "Great job, John. I knew I could count on you. By the way, where did you find the manual?" If your PC or PLC cannot communicate, the
John held up the binder. "I found it in the storage room. It's a great resource. I think we should make sure to keep it in a easily accessible place, in case we need it again."
Mike smiled. "Agreed. Let's make sure to add it to our maintenance library. Well done, John!"
From that day on, John made sure to keep the Convo Inverter Cvf G3 manual in a prominent place, and he became known as the go-to technician for all things related to the plant's inverters.
The manual is typically divided into clear sections:
Based on common support forum queries about the Convo Inverter Cvf G3 Manual:
Q1: Why does my motor run in the wrong direction even after swapping U and V?
Q2: Can the CVF G3 run a single-phase motor?
Q3: How do I reset to factory settings?
Q4: I lost the manual. Can I use the manual for a CVF G2 or G4?
Thank you for choosing the Convo CVF-G3 Series Inverter. This manual provides comprehensive information on installation, parameter setting, operation, and troubleshooting for the CVF-G3 series. To ensure safe and correct operation, please read this manual carefully before installation and keep it accessible for future reference.
