Set Value and Ramp Adjustment
Fig. 6.4.1
Diagram of setpoint and ramp adjustment
The setpoint values of the KEB COMBIVERT F4-F can be adjusted analog (REF1
(REF2) as well as digital. The AUX-function offers the possibility to add an analog
setpoint to other setpoint settings or to use it as amplification factor for speed controller
and torque limits.
The setpoint and rotation selection links the different setpoint sources with the possible
rotation sources. The signal which is received in this manner (except for setpoint
setting directly) is used for the further setpoint calculation.
Only after scanning for the absolute setpoint limits all data which is necessary for the
ramp calculation is available.
