    4.1 Setting of controlling frequency and start/stop commands The Hitachi SJ300/L300P inverters can be configured to take reference set-points and commands from several different locations. Refer to the table below for information of how to configure the inverter so that the Lonworks controls frequency and the commands.

  • Page 12: Chapter5 Lonworks Communication Function

    CHAPTER 5 LONWORKS COMMUNICATION FUNCTION 5.1 Operating the drive via LonMark profile A LonMark profile defines a functional profile for a node communicating with others. A LonMark profile specifies which SNVT’s and SCPT’s to be used and also a semantic meaning about the information being communicated.
  • Page 13 Lon Network, not controled. No message containing a WRITE_DEMAND_CODE (0x02) in the FrameType field of the Hitachi high-speed serial protocol will be communicated to the inverter from the option card. All messages with other FrameType codes will be sent to the inverter.
