Convo Inverter Cvf G3 Manual

Drive detected excessive output current during acceleration, deceleration, or constant speed operation. Remedies: Increase acceleration or deceleration time ( F0.10 / F0.11 ).

Hook up the physical AC motor leads exclusively to terminals U/T1, V/T2, and W/T3 .

Linear V/F, Multi-point V/F, and Sensorless Vector Control (SVC)

Installation Procedures Installation guidance is typically step-by-step: site selection, mounting, AC and DC wiring diagrams, grounding connections, and initial battery configuration. The manual provides torque specifications for terminal connections, cable sizing charts based on current and distance, and recommended fusing/breaker arrangements. It also explains communication setup—such as RS485 or CAN bus connections—for monitoring and integration with external systems. Proper installation ensures electrical safety, minimizes voltage drops, and enables accurate system monitoring.

Internal DC-bus capacitors retain dangerous electrical charges. Wait a minimum of 5 minutes after disconnecting the main power supply before touching any terminal connections. Terminal Layout and Power Wiring Convo Inverter Cvf G3 Manual

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.

Tighten all main circuit power terminals and control strip screws to prevent high-resistance thermal failures.

The CVF-G3 is part of a broader family of products, including the CVF-P3 series for fan and pump applications, and the CVF-G5, which succeeded the G3 series.

: Securely connect the ground terminal to prevent electrical interference and ensure safety. Linear V/F, Multi-point V/F, and Sensorless Vector Control

: Install indoors, free from direct sunlight, corrosive gases, flammable dust, and severe vibration. Installation and Wiring Diagram

: Available in 220V single-phase, 220V three-phase, and 380V–460V three-phase configurations.

Indicators for frequency, current, or voltage display modes. PRG/ESC: Used to enter or exit programming mode. DATA/ENT: Confirms data changes. 3.2 Basic Parameter Setup To start the inverter, standard parameters must be set:

: Running command source (0: Panel, 1: External Terminal). For a safe setup

: Frequency setting method (e.g., panel potentiometer or analog input). F0.04 & F0.05

150% of rated current for 1 minute (General Purpose setting).

Enhances system efficiency while lowering noise levels.

For a safe setup, ensure the following connections are secure and insulated: Power Input : Connect power supply wires to terminals R/L1, S/L2, and T/L3 Motor Output : Connect motor wires to terminals U/T1, V/T2, and W/T3 Control Terminals

Before mounting or powering the drive, verify the physical environment meets the minimum standards defined in the Convo Frequency Converter Instruction Manual :
