Parameter Lists

4 Parameter Lists
FC Series
All = valid for FC 301 and FC 302 series
01 = valid for FC 301 only
02 = valid for FC 302 only
Changes during operation
"TRUE" means that the parameter can be changed while
the adjustable frequency drive is in operation, and "FALSE"
means that the adjustable frequency drive must be
stopped before a change can be made.
4-Set-up
'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': the data value will be the same in all set-ups.

4.1.1 Conversion

The various attributes of each parameter are displayed in
the section Factory Settings. 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 thus
perceived as 10.0.
Examples:
0s --> conversion index 0
0.00s --> conversion index -2
0ms --> conversion index -3
0.00ms --> conversion index -5
