On this circuit board there are components that are sensitive to electrostatic discharges. For further information, refer to Appendix B, “Icons”.5-110PCD2.H100Count modesSC (Single Count):AANDCounting signals at input A. Up and down counting selectable by user program.BFilterTo enable signals at input A to be counted, input B must be connected to 24 V (AND gate).Input AInput BClockCounterModes x1, x2: Up/down counting mode for 2-phase incremental shaft encoderat inputs A and B.x1Input AInput BClockCounterx2Input AInput BClockCounter5-111PCD2.H100Block diagramCounter FlagInput InterfaceCounter enableSetU+S U BCounterD C POutput InterfaceSet CCO Set CCOCounter Status FlagCCOClockup/downCounter ModeInput filtersSC x1 x2ModeInputsABOperating principleThis can be largely derived from the block diagram. It is only necessary to add some explanation about the counter output circuit:
