selector for Preset speeds (0–7). See parameters P3.3.3.1 to P3.3.3.8.
You can use the Preset frequencies function in processes where more than 1 fixed frequency reference is necessary. There are 8
preset frequency references available.
To apply Preset frequencies 1 to 7, connect a digital input to these functions with the instructions in
Inputs.

The ProcessDataIn signals use 2 decimals.
If temperature inputs are selected, the values of parameters P3.12.1.5 Process Unit Minimum and P3.12.1.6 Process Unit Maximum
must be set to correspond to the scale of the temperature measurement board: Process Unit Minimum = -50 °C and Process Unit
Maximum = 200 °C.
