FAQ

What would you control with a 37kW frequency inverter?

With a 37kW variable frequency drive, you can achieve precise control of a wide range of industrial equipment and motor systems. Specifically, 37kW frequency inverters can regulate motor speed, torque output, and start-stop processes to meet the control needs of a wide range of complex operating conditions. Here are some of the key areas you can control with a 37kW inverter:

Motor speed adjustment: The frequency converter can smoothly adjust the motor speed, whether it requires high-speed operation or low-speed fine adjustment, it can be easily achieved. This is particularly important for application scenarios that require precise speed control, such as textile machinery, CNC machine tools, etc.
Energy saving and consumption reduction: By adjusting the motor speed according to actual needs, the frequency converter can effectively reduce the waste of electrical energy and improve energy utilization efficiency. The energy-saving effect is particularly significant when used in equipment with large load changes such as fans and water pumps.
Soft start and soft stop: The frequency converter can realize the soft start and soft stop of the motor, reduce mechanical impact and wear, and extend the service life of the equipment. This is especially important for large or heavy equipment such as cranes, compressors, etc.
Overload protection: When the motor load exceeds the set value, the inverter can automatically adjust the output or stop to protect the motor and mechanical parts from damage. This protection feature improves the security and reliability of the system.
Remote control and monitoring: Modern inverters are usually equipped with communication interfaces and remote monitoring functions, allowing users to remotely monitor and control the operating status of the inverter through the host computer or network to achieve automation and intelligent management.

Please provide the nameplate of your press brake machine. Is it a motor?

Will the parameters be saved when the 37kW inverter performs parameter setting?

For your 37kW frequency inverter, are the parameters saved when set, or is there a process to save them.
