Description
6.4 Setpoint-, Rotation- and Ramp Adjustment
Fig. 6.4.1 Principle of set value and ramp adjustment
The setpoint values of the KEB COMBIVERT F5 can be preadjusted analog as well
as digital. The AUX-function adds or multiplies an analog setpoint to/with other setpoint
settings.
The setpoint and rotation selection links the different setpoint sources with the possible
sources of rotation direction. The signal thus obtained is used for further setpoint
calculation.
Only after interrogation of the absolute setpoint limits, all the data that is required for
the ramp calculation is available.
