3.11.3 Bus Speed Reference Value
Speed reference value is transmitted to the frequency
converter in a relative value in %. The value is transmitted
in the form of a 16-bit word; in integers (0–32767) the
value 16384 (4000 hex) corresponds to 100%. Negative
figures are formatted by 2's complement. The actual
output frequency (MAV) is scaled in the same way as the
bus reference.
