The Convo CVF-G3 manual serves as a critical technical guide for the operation and maintenance of the CVF-G3 series variable frequency drives (VFD). These inverters, now part of the Bosch Rexroth Electronics & Control portfolio, are designed for high-performance industrial motor control, particularly in energy-intensive sectors like water pumps and fans. Core Functionality and Control
The CVF-G3 inverter operates primarily to control the speed and torque of three-phase AC induction motors. The manual details two main operational modes:
Panel Control: Start and stop commands are executed directly via the green and red buttons on the unit's keypad.
Terminal Control: Operation is governed by external wiring to input terminals (S1-S5), allowing for remote automation. Key Programming Parameters
Efficient use of the inverter requires precise parameter settings:
F0.02 (Operation Command): Determines whether control is manual (panel) or automated (terminal).
F0.03 (Frequency Setting): Configures the frequency source, which can be adjusted via a panel potentiometer, high-speed pulse inputs (1–100 kHz), or analog signals (0–10V or 4–20mA).
Frequency Limits: Parameters F0.04 and F0.05 establish the maximum output frequency, essential for protecting motor integrity. Installation and Safety
The manual emphasizes a well-ventilated, indoor installation environment, free from direct sunlight and corrosive gases. Safety protocols are paramount:
Wiring Safety: Power must be disconnected before wiring, and grounding terminals must be properly connected to prevent electrical hazards.
Terminal Constraints: Power should never be connected to the U, V, and W output terminals, as this will result in immediate damage to the inverter.
Environmental Derating: For installations above an altitude of 1,000 meters, the inverter must be derated by 10% for every additional 1,500 meters.
By following the Convo CVF-G3 manual, operators can achieve energy savings of up to 60% in specific applications like air compressors and injection molding machines. CElectrical Kangwo

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?"
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 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).
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).
