HVAC400X – APPLICATION MANUAL
P3.5.4.1.5 AO1 MAXIMUM SCALE (ID 10054)
You can use this parameter to scale the analog output signal.
The scaling values (min and max) are given in the process unit that is specified by the selection of the AO function.
For example, you can make a selection of the output frequency of the drive for the contents of the analog output
signal, and set parameters P3.5.4.1.4 and P3.5.4.1.5 between 10 and 40 Hz. Then the output frequency of the
drive changes between 10 and 40 Hz, and the analog output signal changes between 0 and 20 mA.

Fieldbus Data

P3.6.1 FB DATAOUT 1 SELECTION (ID 852)
You can use this parameter to select the data that is sent to the fieldbus with the ID number of the parameter or
monitor value.
The data is scaled to an unsigned 16-bit format according to the format on the control panel.
For example, value 25.5 on the display equals 255.
P3.6.2 FB DATAOUT 2 SELECTION (ID 853)
You can use this parameter to select the data that is sent to the fieldbus with the ID number of the parameter or
monitor value.
The data is scaled to an unsigned 16-bit format according to the format on the control panel.
For example, value 25.5 on the display equals 255.
P3.6.3 FB DATAOUT 3 SELECTION (ID 854)
You can use this parameter to select the data that is sent to the fieldbus with the ID number of the parameter or
monitor value.
The data is scaled to an unsigned 16-bit format according to the format on the control panel.
