5.1.1 Conversion Index

The various attributes of each parameter are displayed in
the section Factory Settings. Parameter values are
5 5
transferred as whole numbers only. Conversion factors are
therefore used to transfer decimals according to Table 5.6.
Example:

5.1.2 Change during operation

"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 can be made.

1-24 Motor Current has a conversion index of -2 (i.e.
conversion factor of 0.01 according to Table 5.6). To set the
parameter to 2.25 A, transfer the value 225 via Modbus.
The Conversion Factor of 0.01 means that the value
transferred is multiplied by 0.01 in the frequency converter.
The vale 225 transferred on the bus is thus perceived as
2.25 A in the frequency converter.

5.1.3 2-Set-up

"All set-up": The parameter can be set individually in each
of the two set-ups, i.e. one single parameter can have two
different data values.
"1 set-up": Data value will be the same in both set-ups.
