Product Description:

The Danfoss 131L9870 is a strong and efficient variable frequency drive from the VLT FC 101 HVAC Basic Drives line. It is designed to work well in industrial and commercial HVAC systems. It works with a three-phase input voltage of 380–480 V ±10% and gives out 15 kW of power. This makes it good for running big fans, pumps, or compressors under tough conditions. The drive is encased in an IP20-rated container, which protects it from solid objects to some extent. It is meant to be installed within electrical panels.

This model has four programmable digital inputs and two scaled analogue inputs. This makes it easy to connect to building management systems and supports a wide range of control and automation options. Users may easily change how the drive responds to external signals like start/stop orders, speed references, or fault resets using these inputs. To make sure that the data is correct, communication with the 131L9870 is done using established industrial protocols and rigorous framing and error-checking of messages. To start a message, there is a quiet time of at least 3.5 character intervals, which are based on the network's baud rate. The address of the device is sent first, and then the data fields, which are made up of hexadecimal numbers that make up RTU characters.

|After the final character of the message, there should be at least 3.5 character intervals of silence to signify the conclusion of the message. This makes sure that frames are appropriately spaced. If there is a quiet period longer than 1.5 character intervals before the frame is finished, the receiving device throws away the unfinished message and uses the following byte as a new address field.
