Operation mode filling level 1, parameter
Operation mode
440 = 2
This operation mode can be used, for example, for contents level control.
If the actual value is missing, the function brings the output frequency to an adjusta-
ble value.
The minimum value monitoring prevents an acceleration of the drive if the actual
value is missing.
If the actual value is missing (< 0.5%) the output frequency is guided to the
Fixed
frequency
441. This is done using the set
Deceleration (clockwise)
421.
The
Fixed frequency
441 must be in the range between
Minimum frequency
418
and
Maximum frequency
419 . If the
Fixed frequency
441 is set to a value smaller
than the
Minimum frequency
418 , the output frequency is guided to
Minimum fre-
quency
418 . The frequency will not drop below
Minimum frequency
418 .
If the actual value is available again, the controller continues operation automatically.
