5.5 Setting Example

How to calculate the input pulse frequency division ratio
Use the following formula to calculate the input pulse frequency division ratio in Pr. 384:
Maximum number of input pulses (pps) = Pr. 384 × 400
Detectable frequency
The detectable frequency changes with the maximum number of input pulses.
