Operation mode standard, parameter
440 = 1
This operation mode can be used, for example, for pressure or volumetric flow con-
trol with linear operation behavior.
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 Mini-
mum frequency
418. This is done using the set Deceleration (clockwise) 421.
If the actual value is available again, the controller continues operation automatically.
