P3.6.8 FB DATAOUT 8 SELECTION (ID 859)
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 can be necessary to avoid some frequencies because they make
problems of mechanical resonance. With 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)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
P3.7.2 PROHIBIT FREQUENCY RANGE 1 HIGH LIMIT (ID 510)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
P3.7.3 PROHIBIT FREQUENCY RANGE 2 LOW LIMIT (ID 511)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
P3.7.4 PROHIBIT FREQUENCY RANGE 2 HIGH LIMIT (ID 512)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
P3.7.5 PROHIBIT FREQUENCY RANGE 3 LOW LIMIT (ID 513)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
P3.7.6 PROHIBIT FREQUENCY RANGE 3 HIGH LIMIT (ID 514)
Use this parameter to prevent the drive operating on the prohibited frequencies.
In some processes it can be necessary to avoid some frequencies because they cause
mechanical resonance.
