Parameter E2.01, E2.15, H8.20, H8.21, H8.22, H9.00, H9.01, H9.02, H9.03 can
be set to '4: Speed arrival' to configure the digital outputs to show this func-
tion.
The 'Speed arrival' signal is active on the selected output terminal when the
difference between the 'Output frequency' and the 'Setting frequency' is with-
in the range set by parameter E2.70 'Frequency detection width':
