Data 1 ... data 4
A maximum of 4 bytes is available for parameter value entries. Depending on the data
format, these bytes are assigned as follows:
Example
The value "123.45" is to be transferred for a code with the scaling factor "100" and the data
format U32.
Calculation:
Value to be transferred = scaling factor x value
Data
(1 ... 4)
= 100 x 123.45 = 12345 (0x00 00 30 39)

Note!
For all Lenze parameters a scaling factor is specified in the "Factor" column of the
. The scaling factor is important for the transfer of parameter
values which are displayed with one or more decimal places in the parameter
list.
For a scaling factor > 1, the value must be multiplied by the specified scaling
factor before being transferred in order to transfer the value completely (as an
integer). On the SDO client side, the integer then must be divided by the scaling
factor to receive the original value with decimal places.
