Table 7: Inputs

•Default logic level is active high for all inputs.

[a]: UTh is the input switch threshold. To increase the value, a suitable external series resistor must be added. The value of the resistor can be calculated with the formula given in the corresponding subchapters of Board And Connectors. The input states are:

[c]: The cutoff frequency corresponds to a single encoder track.
