of the four set-ups, i. e. one single parameter can have four
dierent data values.

6.16.1 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.
Parameter 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
