Convo Inverter Cvf G3 Manual
: The input voltage is too high, or the motor is decelerating too fast. Increase the deceleration time.
Sensorless Vector Control (SVC), V/F Control, and Torque Control. Starting Torque: 150% at 0.5Hz (SVC mode). Speed Regulation Ratio: 1:100 (SVC). 2. Mechanical Installation Guidelines
: Defines the maximum and upper limit output frequency (default is often 50Hz). Maintenance & Safety
Electrolytic capacitors in the inverter can explode if burned; allow at least 10 minutes after power-off before maintenance. sigi-elect.si Convo Inverter Cvf G3 Manual
Analog input terminal for external potentiometer speed control. AO1: Analog output for frequency or current monitoring.
Digital inputs (e.g., S1 defaults to FWD, S2 to REV). AVI/ACI: Analog inputs for 0-10V or 4-20mA speed signals. RA/RB/RC: Relay output for fault or status signaling.
The manual provides detailed instructions on the physical placement and electrical connections for the CVF-G3/P3 series. : The input voltage is too high, or
: Check technical specs for specific models (like the 3.7KW or 15KW versions) on eBay or SPW Industrial .
: If the operating altitude exceeds 1,000 meters , the unit must be derated by approximately for every 1,500 meters of additional height. Basic Operation & Parameter Setting
When a protective circuit trips, the CVF-G3 displays an alphanumeric code on the LED display. Identify the code below to resolve the underlying issue. Starting Torque: 150% at 0
-10°C to 40°C. Derating is required above 40°C. Humidity: Below 95% RH, non-condensing.
: External switches or PLCs can be wired to terminals for remote operation.
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:
| Terminal | Function | Description | | :--- | :--- | :--- | | L1, L2 (or R, S, T) | AC Input | Connect to commercial power supply (Single phase or 3-phase). | | U, V, W | AC Output | Connect to the 3-phase induction motor. Do NOT connect to power supply! | | P+, PB | Brake Resistor | Terminals for connecting an external brake resistor (if applicable). | | P+, P- | DC Bus | DC link terminals. | | PE | Ground | Earth ground terminal. Must be grounded according to local regulations. |
