The EM730 series frequency converter is a high-reliability, small-size general-purpose frequency converter launched by ZhengXin Electric: the EM730 supports three-phase AC asynchronous motors, and the EM730 permanent magnet non-standard version supports permanent magnet synchronous motors; it supports multiple drive control technologies: vector VF control technology (VVF) and sensorless vector control technology (SVC); it supports both speed and torque output forms, and supports Wi-Fi access and background software debugging functions.
01. Terminal UP/DOWN function
The UP/DOWN speed control function allows users to control the increase or decrease of the inverter's output frequency via external signals (such as buttons, switches, or PLCs), thereby regulating the motor speed. This method has advantages such as ease of operation, rapid response, and high precision, and is widely used in applications requiring frequent motor speed adjustments.
02. Frequency source switching function
Frequency source switching is a very practical function of frequency converters, with a wide range of applications. For example, local and remote switching switches on control cabinets enable local and remote frequency regulation; manual and automatic switching switches enable two control modes for the equipment.
