◆This control cabinet can only start the medium frequency power supply function when the voltage regulator is at zero position, ensuring that the medium frequency power supply outputs from a low potential.
◆After the motor is started by Y-△, the medium frequency indicator light turns on before starting the medium frequency power supply, ensuring full voltage starting of the motor.
◆The motor has thermal relay protection. When the motor overheats, the main circuit is cut off, and the voltage regulator automatically returns to zero position.
◆When the excitation power supply current and the medium frequency output power supply are overloaded, the overcurrent relay operates, cutting off the main circuit, and the voltage regulator automatically returns to zero position.
