Convo CVF-G3 is a general-purpose variable frequency drive (VFD) used to control the speed and torque of AC induction motors. It is commonly used in industrial applications such as pumps, fans, and conveyors. Key Specifications
Voltage Support: Available in 3-phase AC 380V and 1-phase AC 220V models.
Frequency Range: Standard control range is typically 0.0 to 999Hz, with some variants supporting up to 3000Hz. Overload Capacity: 150% rated current for 60 seconds.
Control Modes: Supports V/F control and sensorless vector control (SVC). Wiring & Terminals
Proper wiring is critical for safety. Ensure the input power is off before starting.
Input Terminals: Connect power supply to R/L1, S/L2, and T/L3.
Output Terminals: Connect motor wires to U/T1, V/T2, and W/T3.
Control Terminals: Terminals X1–X6 are used for external control signals like start/stop or multi-speed switching.
Grounding: The PE terminal must be securely connected to a reliable ground point to prevent electric shock. Common Parameters uses a "F" code system for settings:
F0.02: Running command source (0: Panel, 1: External Terminal). Convo Inverter Cvf G3 Manual
F0.03: Frequency setting source (0: Potentiometer, 3: 0–10V Analog, 5: 4–20mA Analog). F0.05: Upper limit frequency (standard default is 50.0Hz). F0.10: Acceleration time.
F0.16: Carrier frequency (2.0–8.0KHz); higher values reduce noise but increase heat. Troubleshooting If the unit trips, common error codes often include: UU: Under-voltage (mains voltage is too low). OV: Over-voltage (often occurs during rapid deceleration). OH: Over-heating (check cooling fans and ventilation).
OC: Over-current (may indicate motor overload or short circuit).

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?" The Convo CVF-G3 series is a well-known line
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.
Convo CVF-G3 is a variable frequency drive (VFD) used to control the speed and torque of AC motors in industrial applications like pumps, fans, and compressors. Since Convo was acquired by Bosch Rexroth
, the CVF-G3 and related series (G2, P2, S1) often share technical documentation under the Bosch brand. Core Specifications
The CVF-G3 series typically supports various power levels and voltage ratings: 220V Level: Ranging from 0.4kW to 3.0kW. 400V Level: Ranging from 0.4kW to 7.5kW. Control Modes:
Digital SVPWM space voltage vector control or standard V/F control. Frequency Range: Output frequency typically ranges from 0.10Hz to 650.00Hz. Key Parameters & Programming
To operate the unit, users must configure basic motor parameters using the keypad or an external device: P0.01 – P0.05: Motor rated voltage, current, frequency, speed, and power. Control mode selection (V/F or Vector).
Frequency source selection (Keypad, analog input, or communication). Running command source (0: Panel, 1: Terminal).
Frequency setting (Options include panel potentiometer, digital buttons, or analog input). Wiring & Terminals
The unit features several multi-function terminals for external control: offer-product.oss-cn-beijing.aliyuncs.com 0-10V analog input for speed setting. 4-20mA analog input. S1 – S5:
Multi-function digital inputs (factory defaults often set S1 for FWD and S2 for REV). Relay output for status monitoring (AC 250V/3A). Safety & Installation Environment:
Installation sites should be clean, dry, well-ventilated, and free from corrosive gases. Common battery charging voltages (examples)
Smaller units (≤7.5kW) are typically IP20 rated with forced air cooling.
Electrolytic capacitors in the inverter can explode if burned; allow at least 10 minutes after power-off before maintenance. sigi-elect.si
