7-5-9 Pulse Input Function Procedures

High-speed Counter Procedure

1,2,3... 1. Determine the Input Mode, reset method, and Numeric Range.

•Counting Speed: 50 kHz or 500 kHz

•Input Mode: Phase Differential, Increment/Decrement, or Pulse + Direc- tion

•Reset method: Phase Z and software reset, or Software reset

•Counter Operation: Circular Counter or Linear Counter

2.Wire the input.

3.Make the necessary System Setup settings.

•Counting Speed: 50 kHz or 500 kHz

•Input Mode: Phase Differential, Increment/Decrement, or Pulse + Direc- tion

•Reset: Phase Z and software reset, or Software reset

•Counter Operation: Circular Counter or Linear Counter

•Count Check Method: Target-value Comparison or Range Comparison

4.If the count check is being used, determine the count check (comparison) method.

5.Create the necessary ladder programming.

•Turn ON the High-speed Counter 1 or 2 Start Bit (A610.00 or A611.00) and start the high-speed counter.

•CTBL(882) instruction: Specifies the port, registers the comparison table, and starts comparison.

•INI(880) instruction: Specifies the port, changes the PV, and starts com- parison.

•PRV(881) instruction: Specifies the port and reads the high-speed counter PV.
