True means that the parameter can be changed while the
frequency converter is in operation, and false means that
the frequency converter must be stopped before a change
5 5
can be made.
4-set-up
All set-ups: The parameter can be set individually in each
of the 4 set-ups, that is 1 single parameter can have 4
different data values.
1 set-up: Data value is the same in all set-ups.

5.1.2 Conversion

The various attributes of each parameter are shown in
Factory Setting. Parameter values are transferred as whole
numbers only. Conversion factors are therefore used to
transfer decimals.
Parameter 4-12 Motor Speed Low Limit [Hz] has a conversion
factor of 0.1. To set the minimum frequency to 10 Hz,
transfer the value 100. A conversion factor of 0.1 means
that the value transferred is multiplied by 0.1. The value
100 is therefore read as 10.0.
Examples:
0 s⇒conversion index 0

0.00 s⇒conversion index -2
