HVAC400X – APPLICATION MANUAL
For example, value 25.5 on the display equals 255.
P3.6.4 FB DATAOUT 4 SELECTION (ID 855)
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.
P3.6.5 FB DATAOUT 5 SELECTION (ID 856)
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.
P3.6.6 FB DATAOUT 6 SELECTION (ID 857)
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.
P3.6.7 FB DATAOUT 7 SELECTION (ID 858)
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.
P3.6.8 FB DATAOUT 8 SELECTION (ID 859)
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.

Prohibit Frequencies

In some processes, it may be necessary to avoid some frequencies because they make problems of mechanical
resonance. Using the Prohibit frequencies function, it is possible to prevent the usage of these frequencies. When
the input frequency reference increases, the internal frequency reference stays at the low limit, until the input
frequency reference is above the high limit.
P3.7.1 PROHIBIT FREQUENCY RANGE 1 LOW LIMIT (ID 509)
You can use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes, it may be necessary to avoid some frequencies because they cause mechanical resonance.
P3.7.2 PROHIBIT FREQUENCY RANGE 1 HIGH LIMIT (ID 510)
You can use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes, it may be necessary to avoid some frequencies because they cause mechanical resonance.
P3.7.3 PROHIBIT FREQUENCY RANGE 2 LOW LIMIT (ID 511)
You can use this parameter to prevent the drive operating on the prohibited frequencies.
