Pulse Inputs Section 7-5
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).
