When we select the right inverter brand, we need to recognize whether it can help enterprises better manage the risks and costs caused by potential safety, security and downtime accidents.
Safety: Reverse arc drives assist users in meeting stringent reverse arc specifications. These Variable-Frequency Drives (VFDs) divert harmful energy and gases from the arc away from plant personnel again. This reduces safety hazards and maintains the equipment. The VFD is also capable of using Safe Torque Shutdown (STO) technology to block the power supply to the motor without blocking the VFD power supply. This is critical to reduce cycle time for batch use and helps to restart systems faster once a security posture is reached. Safe torque shut-off is planned for inverter control and does not require rated electromechanical components, helping to reduce hardware, inventory, and installation costs.
Security: As with every aspect of industrial operations, VFDs are becoming more and more connected. The greater the connectivity, the greater the security risk. If the VFD provides long-distance monitoring and data collection functions, ensure that it is regulated to provide secure connection functions such as Secure Sockets Layer over the Internet connection.
Downtime: In addition to specifying or purchasing a robust VFD to prevent downtime, different levels of support can also assist in monitoring and maintaining the VFD.
For example, VFD, which supports long-distance monitoring, allows suppliers to monitor their own performance. If there is any malfunction, warning or function that is out of order, the supplier will immediately inform the user. In terms of speculative analysis and planning, proactive maintenance can help users identify and respond to any problems that can be completely reduced or prevented by providing predictive equipment health and proactive maintenance. It also eliminates the challenges of skills shortages by assigning VFD monitoring to trusted suppliers.
Medium and low voltage VFDs should help to facilitate the company's business and business approach. When specifying a VFD, look beyond the tag price to understand the lifecycle cost in key areas such as downtime, power usage, system integration, and hazard management.
