Fast I/O Input Data
The fast I/O input data area is used to transfer parameter data directly from the drive via a dual port RAM interface. The following table
details the functions of the fast I/O input data (Bytes 0 to 15). For detailed explanation of the terminal and multi-function inputs and
outputs, refer to the appropriate drive technical manual.

# Parameter Access Area
This area is used to read and write parameter data from and to the drive. The PROFIBUS-DP Master completes the Parameter Access
command (output) message and waits for and then processes the data returned in the Parameter Access response (input) message. These
messages may contain 1 - 4 words of data. The handshaking byte is used to synchronize the communications between the PROFIBUS-DP
Master and the drive. This is necessary due to the additional time required for the drive to process the message. Refer to the Handshaking
section of this chapter for more information on handshaking. Note: Care must be taken when writing certain parameters to the drive as
other parameters may be dependant on them. Control method, A1-02, maximum Frequency, E1-04, and Acc/Dec Scale Time, C1-10, are
just a few. Refer to the appropriate drive MODBUS
