Conversion:
Under the section entitled Factory Settings the vari-
ous attributes of each parameter are displayed. As a
parameter value can only be transferred as a whole
number, a conversion factor must be used to transfer
decimals.
E
xample:
Parameter 201 Output frequency, low limit f
MIN
has a
conversion factor of 0.1. If you wish to preset the
minimum frequency to 10 Hz, the value 100 must be
transferred, as a conversion factor of 0.1 means that
the value transferred is multiplied by 0.1. The value
100 will thus be perceived as 10.0.
