Prescale Function (Counter)
Start Point Function (Counter)
In case of counter operation, set the start value for counting at Start point [
START
].

output mode, it counts up and PV starts from the start point value.
This function is to set and display calculated unit for actual length, liquid, position, etc. It is called “prescale value” for measured length, liquid,
or position, etc per 1 pulse. For example, when moving L, the desired length to be measured, and P, the number of pulses per 1 revolution of
a rotary encoder, occurs, prescale value is L/P.
