Maximally 4 bytes are available for parameter value entries. Depending on the data
format, they are assigned as follows:
Example
A value of "123.45" is to be transmitted for a code, unit: "%" (e.g. C00039/1: "Fixed setpoint-
JOG1").
In controllers of the 8400 series, parameters with the "%" unit have two decimal positions
and hence a scaling factor of "100".
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.
