10.8 Ratio Conversion
10.8 Ratio Conversion
An input signal multiplied with the set ratio (x/y) is output from the multi function counter block.
Ratio conversion enables the following controls.
• An encoder output of the motor at the unwinding part is input to the programmable controller to control the motor speed of
lines with distribution output.
• The motor speed of multiple lines, for example, a printer, can be controlled.
The ratio (x/y) used in ratio conversion must be "y ≥ x" when a signal multiplied by x/y is output to an input signal. Conversions
with the ratio exceeding one time cannot be performed.
The following describes a link and parameter example of a ratio conversion. With the example setting, when a 1ms input
signal is output for 1ms after multiplied with 3/10. Note that this link example is for when a 32-bit unsigned multi function
counter block is used.
