Conventional Formats
The 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 Data
■
High-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-DP
communications, the drive Run/Stop and Frequency Reference commands are typically transferred to the drive within 2 ms after being received by
the option.
MEMOBUS/Modbus Message
■
MEMOBUS/Modbus message data is transferred to the drive using MEMOBUS/Modbus messages. All drive parameters and data can be accessed
through MEMOBUS/Modbus. Because the data in this message type is transferred to the drive after the SI-P3 receives and edits it, more time is
required to return the data to the master. The master must synchronize the timing of sending and receiving the data by handshaking.
Memory Maps
■
The following memory maps show the I/O data bytes.

<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 torque
limit 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 output
frequency 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 Normal
Duty or Heavy Duty operation.
