Actual length (Fb-06) = Number of pulses sampled by DI is divided by Fb-07 (Number of pulses
each meter).
When actual length reaches the value set in Fb-05, digital output terminal set for function 10
“Length reached” becomes on. Length reset can be implemented via DI terminal set for function
28 "Length reset".
