 Application Scope  

Suitable for general-purpose applications, it can drive devices such as water pumps, and is also used in numerous general applications such as conveyor belts, mixers, extruders, fans, compressors, and basic material handling machinery.  

The Siemens 6SL3210-1KE18-8UF1 supports the following communication protocols:  

 PROFINET  Siemens 6ES7231-5QA30-0XB0 module* 

This frequency converter integrates the PROFINET-PN bus, enabling high-speed, real-time communication with other PROFINET-compatible devices. It is commonly used in industrial automation systems to achieve fast data exchange and control between devices, such as connecting with Siemens PLCs and other equipment.  

 USS  6ES7142-5AF00-0BA0 Siemens* 

It supports the USS (Universal Serial Communication Interface) protocol for data exchange via an RS485 interface. The USS protocol is a communication protocol developed by Siemens specifically for drive devices, using a single-master "master-slave" access mechanism where the master continuously polls each slave, and slaves respond to received commands. It can be used to connect frequency converters with higher-level automation systems, but typically requires corresponding hardware interface support (such as the relevant serial port on the frequency converter) to implement protocol communication.  Siemens 1FL6034-2AF21-1LH1 Servo Motor*

Under normal circumstances, this frequency converter has the PROFINET protocol integrated by default, and the USS protocol is also commonly supported for communication with other devices via serial ports. For special requirements, other communication protocols such as PROFIBUS-DP can be supported through optional communication boards (Note: The 6SL3210-1KE18-8UF1 itself integrates PROFINET, and PROFIBUS-DP requires additional options; descriptions in different materials may vary slightly due to configuration differences, generally giving priority to integrated PROFINET and natively supported USS as common protocols).
