Overview
In this example, the resolution of encoder is 1000 pulses/rotation.
Formula for calculation of rotation per minute
Enter phase signal from encoder in R0.0 and R0.1, and measure count
numbers per second. Calculate rotation per minute.
In this example, the resolution of encoder is 1000 pulses/rotation.
Rotation per minute is stored in DT6 and DT7 for later checking with
monitor functions of programming tools such as WinGPC S/W.
Enter phase signal in R0.0 and R0.1, and measure every second.
In this example, the resolution of encoder is 1000 pulses/rotation.
Rotation per minute is stored in DT 6 and DT7 for later checking with
monitor functions of programming tools such as WinGPC S/W.
