1.

Determine the Counting Speed, Input Mode, Reset Method, and Counter
Operation.

• 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.

• Counter Data Display: Counter movements (mode 1)

4.

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.

• Turn ON the Measurement Start Bit (A610.02 or A611.02).
