”TRUE” means that the parameter can be changed while
the frequency converter is in operation. “FALSE” means
that the frequency converter must be stopped before a
change can be made.

'All set-ups': the parameter can be set individually in each
of the four set-ups, i. e. one single parameter can have
four different data values.
’1 set-up’: data value will be the same in all set-ups.

Conversion
The various attributes of each parameter are displayed in
Factory Setting. Parameter values are transferred as whole
numbers only. Conversion factors are therefore used to
transfer decimals.
4-12 Motor Speed Low Limit [Hz] has a conversion factor of
0.1. To preset 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:
0s ⇒ conversion index 0
0.00s ⇒ conversion index -2
0ms ⇒ conversion index -3
0.00ms ⇒ conversion index -5
