4.1.1 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.
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
