Operation Mode
Operation mode filling level 2, parameter 440 = 3
This operation mode can be used, for example, for contents level control.
The minimum value monitoring prevents an acceleration of the drive if the actual
value is missing.
Fixed
If the actual value is missing (< 0.5%) the output frequency is guided to the
frequency Deceleration (clockwise)
441. This is done using the set
421.
If there is no control deviation (actual value =reference value) or if the control devia-
tion is negative (actual value>reference value), the output frequency is guided to
Minimum frequency Deceleration (clockwise)
418. This is done using the set
421.
The drive accelerates as soon as an actual value is present again or the control devia-
Hysteresis
tion exceeds the positive 443. The drive stops as soon as the the control
Hysteresis
deviation falls below the negative
443.
