9.7.2.3 Data 1 ... data 4
Maximally 4 bytes are available for parameter value entries. Depending on the data format, they are
assigned as follows:
Example
For a code with the scaling factor "100" and the data format U32 the value "123.45" is to be
transmitted.
Calculation:
• Value to be transmitted = scaling factor x value
• Data
(1 ... 4)
= 100 x 123.45 = 12345 (0x00 00 30 39)

Note!
The "Factor" column of the Table of attributes contains a so-called scaling factor for all
Lenze parameters. The scaling factor is relevant to the transfer of parameter values
which have one or more decimal positions in the parameter list.
If the scaling factor is > 1, the value must be multiplied by the indicated scaling factor
prior to transmission to be able to transfer the value as an integer. At the SDO client end,
the integer must be divided by the scaling factor to obtain the original value including
decimal positions again.
