Mode 1 Procedure

1,2,3... 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).
