Note:
The parameterization of the technology controller in the individual data
sets enables an adaptation to various operating points of the application
with the data set change-over via control contacts.
Note:
The technology controller operates in motor clockwise operation. The di-
rection of rotation can be changed via parameter
Change Sense of Rota-
tion
1199. Refer to chapter 9.2.8 „Change sense of rotation“.
Operation mode standard, parameter
Operation mode
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.
