The setpoint is transferred as a whole number with a value range of -32768 to 32767 (8000 hex to 7FFF hex).
The value 16384 (4000 hex) is equal to 100%. The value C000 HEX corresponds to -100%. A setpoint of
100% corresponds to the parameter maximum frequency (parameter P105) set in the same parameter set.
