Speed Selection Table
The following table shows the combinations of the digital input and the according speed.
If b1-02 is set to “1”, speed 1 is input as analog reference at terminal A1 or Channel CH1 of an analog input
option card AI-14B if it is installed.
If an AI-14B option card is used and the functions for channel CH2 and CH3 are set to “Auxiliary Frequency
2” (H3-05/09=2) and “Auxiliary Frequency 3” (H3-05/09=3).
Nominal / Leveling Speed Detection with Multi Speed Inputs
Using this function the inverter can distinguish between the nominal and leveling speed when the speed selec-
tion is done by multifunction inputs which is required by other functions like the ASR controller, short floor
operation and slip compensation for V/f control.
