Manual: Convo Inverter Cvf G3

Connect the 3-phase power supply to L1, L2, L3 . Motor Terminals: Connect the motor leads to U, V, W .

Causes: Input voltage is below minimum operational specifications or main contactor failed.

Connect incoming AC power lines to terminals (for 3-phase units) or R and T (for single-phase units). Convo Inverter Cvf G3 Manual

: After turning off the power, wait at least 10 minutes before touching the radiator or internal components to prevent burns or electric shock from residual charges.

Are you controlling it via the ? I can provide the exact parameter sequence for your setup. Connect the 3-phase power supply to L1, L2, L3

For industrial liquid-pumping systems or constant-pressure ventilation networks, the CVF-G3 features an internal proportional-integral-derivative (PID) tracking system.

Check motor insulation, wiring leads, and output phases for short circuits. Reduce mechanical load torque or check for a locked rotor.

Includes Sensorless Vector Control (SVC) and SVPWM for high speed and torque accuracy. Protection:
