13.5 Response Time of the Frequency Error Evaluation
Response time with a sudden frequency drop:
Time calculations in the subsequent tables assume the following settings:
Sampling Time = 10 ms, Wait Time = 100 ms
- Use Sampling Time for the calculation when f > 1/Sampling Time
- Use reciprocal frequency 1/f when f < 1/Sampling Time
In addition to the delay times shown in the tables below, please add also the
hardware delay time of the corresponding output
(relay = 25 ms, analog output = 1 ms, digital output = 1 ms). The parameter Filter
is excluded.
*) Calculated values for response times assume that “Sampling Time” would be
greater than the reciprocal frequency 1/f.
