20 YASKAWA ELECTRIC SIEP C730600 42B 1000-Series Option SI-P3 Technical Manual7 Option Data and I/O Maps7 Option Data and I/O Maps Conventional FormatsThe configuration tool of PROFIBUS-DP master sets the input and output data length of SI-P3 from Extended Data 1(32 bytes), Extended Data 2 (12 bytes), and Basic Data (6 bytes).Conventional formats have two message types: High-speed I/O Data and MEMOBUS/Modbus message. Set parameterF6-32 to 1 to use conventional formats. High-Speed I/O DataHigh-speed I/O data is directly transferred between the drive and controller or PLC. When the drive is set forPROFIBUS-DP communications, the drive Run/Stop and Frequency Reference commands are transferred within 2 msafter being received by the option. MEMOBUS/Modbus MessageMEMOBUS/Modbus message data is transferred between the drive and controller or PLC using MEMOBUS/Modbusmessages. All drive parameters and data can be accessed through MEMOBUS/Modbus. The data in this message type istransferred to the drive after being received and edited by the option and more time is required to return the data to themaster. The master must synchronize the timing of sending and receiving the data by a process called handshaking.Refer to Handshaking Register on page 25 for more information. Memory MapsThe following memory maps show the I/O data bytes.

When enabled, d5-01determines whether the value is read as the torque limit value (d5-01 = 0) or as the torque reference value (d5-01 = 1). In CLV/PM, this value isread as the torque limit.<3> Unit depends on the setting of o1-03 (Digital Operator Display Scaling). When the drive is operating in V/f Control or OLV/PM, the driveoutput frequency becomes the input data.<4> Data is displayed in units of 0.01 A for drives 7.5 kW and smaller, and in units of 0.1 A for drives 11 kW and larger. This convention is the sameregardless of drive duty mode selection.Description Byte Description0 Operation Command High Byte 0 Drive Status High Byte1 Operation Command Low Byte 1 Drive Status Low Byte2 Frequency Reference High Byte 2 Motor Speed High Byte <3>3 Frequency Reference Low Byte 3 Motor Speed Low Byte <3>4 Torque Reference/Torque Limit High Byte <1> <2> 4 Output Current High Byte <4>5 Torque Reference/Torque Limit Low Byte <1> <2> 5 Output Current High Byte <4>Output (Master Device to Drive) Input (Drive to Master Device)Byte Description Byte Description0 Operation Command High Byte 0 Drive Status High Byte1 Operation Command Low Byte 1 Drive Status Low Byte2 Frequency Reference High Byte 2 Motor Speed High Byte <5>3 Frequency Reference Low Byte 3 Motor Speed Low Byte <5>4 Torque Reference High Byte <1> <2> 4 Torque Reference Monitor High Byte <6>
