The EM730 series inverter is a high-reliability, small-sized general-purpose inverter launched by Sine Electric: EM730 supports three-phase AC asynchronous machines, and EM730 permanent magnet non-standard supports permanent magnet synchronous motors. Supports a variety of drive control technologies: vector VF control technology (VVF) and speed sensorless vector control technology (SVC); supports two output forms of speed and torque, and supports Wi-Fi access function and background software debugging function.
01 External potentiometer speed adjustment
The external potentiometer of the frequency converter can be used as a way to adjust the frequency. By adjusting the resistance of the potentiometer by rotating and sliding, the magnitude of the voltage or current signal input to the inverter can be changed, thereby controlling the output frequency of the inverter and achieving the effect of adjusting the speed of the motor.

02 Three-wire control start and stop
Frequency converter three-wire control start and stop is a commonly used motor control method. The starting, direction switching and stopping of the motor are realized through three points. The three-wire control start-stop circuit of the frequency converter has a simple structure and is easy to operate, providing more flexibility for controlling the motor and is suitable for more industrial applications.

Precautions
>In practical applications, the appropriate inverter model and parameters need to be selected according to specific equipment and working conditions.
>When wiring, you need to follow the instructions of the frequency converter to ensure the correctness and reliability of the wiring.
>During use, attention should be paid to safe operation to avoid accidents such as electric shock and short circuit.
