The setpoint and actual values are transferred as standards. The standardization and reference values are stored in parameters P2000 to P2004 of the MM440.
16384dez = 4000hex = 100% applies here, with 100% referring to the reference value for the transferred variable.

Example:

If P2000 (reference frequency) is 50 Hz and if a speed of16,67 Hz shall be run, then 33% or 5461dec must be transferred

Operating Instructions: MICROMASTER PROFIBUS Optional Board

"Frequency target value and actual value are normalised so that 4000hex corresponds with 50Hz."
