Configuration of the Main Type in Modulo-loop Mode

Configuration Procedure

Step	Action
1	Double-click Embedded Functions > HSC.
2	Select the HSC• tab.
3	Set the value of the HSC > HSC0• > Type parameter to Main.
4	Set the value of the HSC > HSC0• > Parameter > Mode parameter to Modulo-loop.
5	Enter the value of the HSC > HSC0• > Parameter > Preset/Modulo parameter.
6	Select the value of the HSC > HSC0• > Clock Inputs > Input mode parameter.
7	Select the value of the HSC > HSC0• > Clock Inputs > A Filter parameter. If necessary, select the value of the HSC > HSC0• > Clock Inputs > B Filter parameter.
8	Optionnally, you can enable these functions: ocapture function ocomparison function oenable function opreset function

NOTE: The IO Summary window displays the DM72F• I/O mapping. You can see the I/O used by expert function.

Programmable Filter

The filtering value on the Main type input determines the counter maximum frequency as shown in this table:

Input Parameter

The value of the Input mode parameter determines the counting behavior:

Parameter Value	Description
A Single Phase	The counter increments on A.
A=UP, B=DOWN	The counter increments on A and decrements on B.
A=Pulse, B=Direction	oIf there is a rising edge on A and B = True, the counter decrements. oIf there is a rising edge on A and B = False, the counter increments.
Normal Quadrature X1	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o1 count by encoder cycle
Normal Quadrature X2	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o2 counts by encoder cycle
Normal Quadrature X4	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o4 counts by encoder cycle
Reverse Quadrature X1	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o1 count by encoder cycle
Reverse Quadrature X2	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o2 counts by encoder cycle
Reverse Quadrature X4	oA physical encoder always provides 2 signals 90° shift that first allows the counter to count pulses and detect direction o4 counts by encoder cycle
