Scaling factor
The "scaling factor" is important for parameter access via a bus system.
Example 1: The value "654" of the parameter
(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
(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".
[17-2] Conversion formula for write access via bus system
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.
