7 Conventional FormatsYASKAWA ELECTRIC SIEP C730600 42A YASKAWA AC Drive-Option Card PROFIBUS-DP Technical Manual 157 Conventional Formats◆ 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 parameter F6-32 to “1” to use conventional formats.■ High-Speed I/O DataHigh-speed I/O data is directly transferred to or from the drive and can control the drive. For example, when the drive is set for PROFIBUS-DPcommunications, the drive Run/Stop and Frequency Reference commands are typically transferred to the drive within 2 ms after being received bythe option.■ MEMOBUS/Modbus MessageMEMOBUS/Modbus message data is transferred to the drive using MEMOBUS/Modbus messages. All drive parameters and data can be accessedthrough MEMOBUS/Modbus. Because the data in this message type is transferred to the drive after the SI-P3 receives and edits it, more time isrequired to return the data to the master. The master must synchronize the timing of sending and receiving the data by handshaking.■ Memory MapsThe following memory maps show the I/O data bytes.■ Basic and Extended Register MapsTable 8 Basic Data Register Map DetailTable 9 Extended Data 1 Register MapBasic Data(6 bytes)Extended Data 1(32 bytes)Extended Data 2(12 bytes)High-speed I/O Data Bytes 0 to 5 Bytes 0 to 15 Bytes 0 to 3MEMOBUS/Modbus Data – Bytes 16 to 31 Bytes 4 to 11Output (Master Device → Drive) Input (Drive → Master Device)Byte<1> Enabled in CLV, AOLV/PM, and CLV/PM control modes (A1-02 = 3, 6, or 7).<2> Set when network communication is designated as the source of the torque limit and torque reference (F6-06 = 1).When enabled, d5-01 determines whether the value is read as the torquelimit value (d5-01 = 0) or read as the torque reference value (d5-01 = 1). In Closed Loop Vector for PM motors, this value is read as the torque limit.<3> Unit depends on the setting of o1-03 (Digital Operator Display Scaling). When the drive is operating in the V/f Control mode or Open loop vector for PM mode, the drive's outputfrequency becomes the input data.<4> Data is displayed in units of either 0.01 A for drives 7.5 kW and smaller, or in units of 0.1 A for drives 11 kW and larger. This is the same regardless of whether the drive is set for NormalDuty or Heavy Duty operation.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 → Drive) Input (Drive → 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>5 Torque Reference Low Byte <1> <2> 5 Torque Reference Monitor Low Byte <6>6 Torque Compensation High Byte <1> 6 Speed Detection PG Pulse Count 1 High Byte7 Torque Compensation Low Byte <1> 7 Speed Detection PG Pulse Count 1 Low Byte8 Reserved 8 Frequency Reference High Byte9 9 Frequency Reference Low Byte10 Analog Output Channel 1 High Byte <3> 10 Output Frequency High Byte11 Analog Output Channel 1 Low Byte <3> 11 Output Frequency Low Byte12 Analog Output Channel 2 High Byte <3> 12 Output Current High Byte <7>13 Analog Output Channel 2 Low Byte <3> 13 Output Current Low Byte <7>14 Digital Output High Byte <4> 14 Analog Input Channel 1 High Byte15 Digital Output Low Byte <4> 15 Analog Input Channel 1 Low Byte16 MEMOBUS/Modbus Function Code 16 MEMOBUS/Modbus Function Code17 MEMOBUS/Modbus Starting Register Address High Byte 17 MEMOBUS/Modbus Starting Register Address High Byte18 MEMOBUS/Modbus Starting Register Address Low Byte 18 MEMOBUS/Modbus Starting Register Address Low Byte19 MEMOBUS/Modbus Number of Data 19 MEMOBUS/Modbus Number of Data20 MEMOBUS/Modbus Data 1 High Byte 20 MEMOBUS/Modbus Data 1 High Byte
