Scaling factor
The "scaling factor" is important for parameter access via a bus system.
Example 1: The value "654" of the parameter C00028/1 (AIN1: input voltage) read via a bus system
must be divided by the corresponding scaling factor "100" to obtain the actual display value
"6.54 V".

Example 2: In order to set the parameter C00012 (acceleration time main setpoint) to the value
"123.45 %" via a bus system, the integer value "12345" must be transferred, i.e. the value to be set
must be multiplied by the corresponding scaling factor "100".

Character length
In case of parameters of "VISIBLE_STRING" data type, the character length is given in addition. This
is also important for the parameter access via a bus system.
