<1> If connector input p2654 is assigned a connector input <> 0, the control signals "select positioning type", "direction selection positive" and "direction input
negative" are internally supplied with values from this output. Based on the value of the connector input, the following Ids are evaluated xxXx:
xx0x = absolute => p2648; xx1x = relative => p2648; xx2x = ABS_POS => p2648, p2651; xx3x = ABS_NEG => p2648, p2652.
<2> Only evaluated with transfer type "edge evaluation" (BI: p2649 = 0 signal).
<3> The connector outputs are only supplied with values from here if the "direct setpoint input MDI" mode is active.
<4> For the transfer type "continuous transfer" (BI: p2649 = 1 signal), relative positioning is not permissible.
