Set Value and Ramp Adjustment
Picture 6.4.1 Principle of set value and ramp adjustment
The set values of the KEB COMBIVERT F4-C can be adjusted analog (±REF / REF)
as well as digital. The AUX-function offers the possibility to combine an analog set
value with other set value adjustments.
The selection of set value and rotation direction links the different set value sources
with the possible sources for direction of rotation. The signal, received in this way, is
used for the further set value calculation.
Not until the absolute set value limits are queried, all data required for the ramp
calculation are given.
