3.2.89.1 Switching points
l Switching points can be set in two ways:
– Mode 1: Start and end position
– Mode 2: Centre with switching range
l The switching points are selected by means of the variable table VTPOSC.
– Direct input of switch−on and switch−off positions, centre and switching range in VTPOSC.
l If the value at SPCx−L−IN is within the range of the switching points sets, SPCx−STATx = HIGH
