Precautions for Correct Use
The Encoder Counter Operation Command parameter is normally used by assigning it as I/O
data. However, do not assign this parameter as I/O data when you assign it to an MC Function
Module axis.
When you assign the parameter to an MC Function Module axis, manipulate the parameter
through the MC Function Module axis and not in the parameter itself.
The bit configuration of the Pulse Period Measurement Function parameter is given in the following
table.
n: Channel number
