CHAPTER 1 OVERVIEW
1.1 Overview
This User's Manual describes the specifications, handling, wiring and programming
methods of the Channel Isolated Pulse Input Module (QD60P8-G) used with the
MELSEC-Q series programmable controller CPU.
The QD60P8-G counts the input pulse number (speed, rotation speed, instant flux or
similar) and measures the quantity the length, accumulating flux and so forth. The input
pulse value is updated every 10ms. The QD60P8-G updates the accumulating count
value and the pulse number after movement averaging processing or similar (sampling
pulse number) at intervals of the count cycle setting value.

1) Pulse input voltage
A single module accepts the pulse inputs of 5VDC/12 to 24VDC.
2) Pulse edge selection
It is allowed to select the rise or fall of the input pulses to be counted.
3) Pre-scale function
The input pulse number is multiplied by any value to convert the pulse
number.
4) Movement averaging function
The values of the sampling pulse number are averaged by the specified
number of times to calculate the average value.
